** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
** layer a hint of how large the database file will grow to be during the
** current transaction.  This hint is not guaranteed to be accurate but it
** is often close.  The underlying VFS might choose to preallocate database
** file space based on this hint in order to help writes to the database
** file run faster.
**
** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
** implements [sqlite3_deserialize()] to set an upper bound on the size
** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
** If the integer pointed to is negative, then it is filled in with the
** current limit.  Otherwise the limit is set to the larger of the value
** of the integer pointed to and the current database size.  The integer
** pointed to is set to the new limit.
**
** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
** extends and truncates the database file in chunks of a size specified
** by the user. The fourth argument to [sqlite3_file_control()] should 
** point to an integer (type int) containing the new chunk-size to use
** for the nominated database. Allocating database file space in large
** chunks (say 1MB at a time), may reduce file-system fragmentation and

**            same token for inputs "first" and "1st". Say that token is in
**            fact "first", so that when the user inserts the document "I won
**            1st place" entries are added to the index for tokens "i", "won",
**            "first" and "place". If the user then queries for '1st + place',
**            the tokenizer substitutes "first" for "1st" and the query works
**            as expected.
**
**       <li> By adding multiple synonyms for a single term to the FTS index.
**            In this case, when tokenizing query text, the tokenizer may 
**            provide multiple synonyms for a single term within the document.
**            FTS5 then queries the index for each synonym individually. For
**            example, faced with the query:
**       <li> By querying the index for all synonyms of each query term
**            separately. In this case, when tokenizing query text, the
**            tokenizer may provide multiple synonyms for a single term 
**            within the document. FTS5 then queries the index for each 
**            synonym individually. For example, faced with the query:
**
**   <codeblock>
**     ... MATCH 'first place'</codeblock>
**
**            the tokenizer offers both "1st" and "first" as synonyms for the
**            first token in the MATCH query and FTS5 effectively runs a query

**            Using this method, when tokenizing document text, the tokenizer
**            provides multiple synonyms for each token. So that when a 
**            document such as "I won first place" is tokenized, entries are
**            added to the FTS index for "i", "won", "first", "1st" and
**            "place".
**
**            This way, even if the tokenizer does not provide synonyms
**            when tokenizing query text (it should not - to do would be
**            when tokenizing query text (it should not - to do so would be
**            inefficient), it doesn't matter if the user queries for 
**            'first + place' or '1st + place', as there are entries in the
**            FTS index corresponding to both forms of the first token.
**   </ol>
**
**   Whether it is parsing document or query text, any call to xToken that
**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit

** A CellArray object contains a cache of pointers and sizes for a
** consecutive sequence of cells that might be held on multiple pages.
**
** The cells in this array are the divider cell or cells from the pParent
** page plus up to three child pages.  There are a total of nCell cells.
**
** pRef is a pointer to one of the pages that contributes cells.  This is
** used to access information such as MemPage.intKey and MemPage.pBt->pageSize
** which should be common to all pages that contribute cells to this array.
**
** apCell[] and szCell[] hold, respectively, pointers to the start of each
** cell and the size of each cell.  Some of the apCell[] pointers might refer
** to overflow cells.  In other words, some apCel[] pointers might not point
** to content area of the pages.
**
** A szCell[] of zero means the size of that cell has not yet been computed.
**
** The cells come from as many as four different pages:
**
**             -----------
**             | Parent  |
**             -----------
**            /     |     \
**           /      |      \
**  ---------   ---------   ---------
**  |Child-1|   |Child-2|   |Child-3|
**  ---------   ---------   ---------
**
** The order of cells is in the array is for an index btree is:
**
**       1.  All cells from Child-1 in order
**       2.  The first divider cell from Parent
**       3.  All cells from Child-2 in order
**       4.  The second divider cell from Parent
**       5.  All cells from Child-3 in order
**
** For a table-btree (with rowids) the items 2 and 4 are empty because
** content exists only in leaves and there are no divider cells.
**
** For an index btree, the apEnd[] array holds pointer to the end of page
** for Child-1, the Parent, Child-2, the Parent (again), and Child-3,
** respectively. The ixNx[] array holds the number of cells contained in
** each of these 5 stages, and all stages to the left.  Hence:
**
**    ixNx[0] = Number of cells in Child-1.
**    ixNx[1] = Number of cells in Child-1 plus 1 for first divider.
**    ixNx[2] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
**    ixNx[3] = Number of cells in Child-1 and Child-2 + both divider cells
**    ixNx[4] = Total number of cells.
**
** For a table-btree, the concept is similar, except only apEnd[0]..apEnd[2]
** are used and they point to the leaf pages only, and the ixNx value are:
**
**    ixNx[0] = Number of cells in Child-1.
**    ixNx[1] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
**    ixNx[2] = Number of cells in Child-1 and Child-2 + both divider cells

** the label is resolved to a specific address, the VDBE will scan
** through its operation list and change all values of P2 which match
** the label into the resolved address.
**
** The VDBE knows that a P2 value is a label because labels are
** always negative and P2 values are suppose to be non-negative.
** Hence, a negative P2 value is a label that has yet to be resolved.
** (Later:) This is only true for opcodes that have the OPFLG_JUMP
** property.
**
** Variable usage notes:
** Zero is returned if a malloc() fails.
**
**     Parse.aLabel[x]     Stores the address that the x-th label resolves
**                         into.  For testing (SQLITE_DEBUG), unresolved
**                         labels stores -1, but that is not required.
**     Parse.nLabelAlloc   Number of slots allocated to Parse.aLabel[]
**     Parse.nLabel        The *negative* of the number of labels that have
**                         been issued.  The negative is stored because
**                         that gives a performance improvement over storing
**                         the equivalent positive value.

#ifndef SQLITE_OMIT_SUBQUERY
/*
** Generate code for scalar subqueries used as a subquery expression, EXISTS,
** or IN operators.  Examples:
** Generate code that will construct an ephemeral table containing all terms
** in the RHS of an IN operator.  The IN operator can be in either of two
** forms:
**
**     (SELECT a FROM b)          -- subquery
**     EXISTS (SELECT a FROM b)   -- EXISTS subquery
**     x IN (4,5,11)              -- IN operator with list on right-hand side
**     x IN (SELECT a FROM b)     -- IN operator with subquery on the right
**
** The pExpr parameter describes the expression that contains the IN
** operator or subquery.
** The pExpr parameter is the IN operator.  The cursor number for the
** constructed ephermeral table is returned.  The first time the ephemeral
** table is computed, the cursor number is also stored in pExpr->iTable,
** however the cursor number returned might not be the same, as it might
** have been duplicated using OP_OpenDup.
**
** If parameter isRowid is non-zero, then expression pExpr is guaranteed
** to be of the form "<rowid> IN (?, ?, ?)", where <rowid> is a reference
** to some integer key column of a table B-Tree. In this case, use an
** intkey B-Tree to store the set of IN(...) values instead of the usual
** (slower) variable length keys B-Tree.
**
** If rMayHaveNull is non-zero, that means that the operation is an IN
** (not a SELECT or EXISTS) and that the RHS might contains NULLs.
** All this routine does is initialize the register given by rMayHaveNull
** to NULL.  Calling routines will take care of changing this register
** value to non-NULL if the RHS is NULL-free.
** If parameter isRowid is non-zero, then LHS of the IN operator is guaranteed
** to be a non-null integer. In this case, the ephemeral table can be an
** table B-Tree that keyed by only integers.  The more general cases uses
** an index B-Tree which can have arbitrary keys, but is slower to both
** read and write.
**
** If the LHS expression ("x" in the examples) is a column value, or
** the SELECT statement returns a column value, then the affinity of that
** column is used to build the index keys. If both 'x' and the
** SELECT... statement are columns, then numeric affinity is used
** if either column has NUMERIC or INTEGER affinity. If neither
** 'x' nor the SELECT... statement are columns, then numeric affinity
** is used.

** is the name of the target database file. In this case, on UNIX, if the
** state database is not already present in the file-system, it is created

** with the same permissions as the target db is made. 
**
** With an RBU vacuum, it is an SQLITE_MISUSE error if the name of the

** use.
**
** This function does not delete the state database after an RBU vacuum
** is completed, even if it created it. However, if the call to
** sqlite3rbu_close() returns any value other than SQLITE_OK, the contents
** of the state tables within the state database are zeroed. This way,
** the next call to sqlite3rbu_vacuum() opens a handle that starts a

**            same token for inputs "first" and "1st". Say that token is in
**            fact "first", so that when the user inserts the document "I won
**            1st place" entries are added to the index for tokens "i", "won",
**            "first" and "place". If the user then queries for '1st + place',
**            the tokenizer substitutes "first" for "1st" and the query works
**            as expected.
**
**       <li> By adding multiple synonyms for a single term to the FTS index.
**            In this case, when tokenizing query text, the tokenizer may 
**            provide multiple synonyms for a single term within the document.
**            FTS5 then queries the index for each synonym individually. For
**            example, faced with the query:
**       <li> By querying the index for all synonyms of each query term
**            separately. In this case, when tokenizing query text, the
**            tokenizer may provide multiple synonyms for a single term 
**            within the document. FTS5 then queries the index for each 
**            synonym individually. For example, faced with the query:
**
**   <codeblock>
**     ... MATCH 'first place'</codeblock>
**
**            the tokenizer offers both "1st" and "first" as synonyms for the
**            first token in the MATCH query and FTS5 effectively runs a query 
**            similar to:

**            Using this method, when tokenizing document text, the tokenizer
**            provides multiple synonyms for each token. So that when a 
**            document such as "I won first place" is tokenized, entries are
**            added to the FTS index for "i", "won", "first", "1st" and
**            "place".
**
**            This way, even if the tokenizer does not provide synonyms
**            when tokenizing query text (it should not - to do would be
**            when tokenizing query text (it should not - to do so would be
**            inefficient), it doesn't matter if the user queries for 
**            'first + place' or '1st + place', as there are entries in the
**            FTS index corresponding to both forms of the first token.
**   </ol>
**
**   Whether it is parsing document or query text, any call to xToken that
**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit

** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
** layer a hint of how large the database file will grow to be during the
** current transaction.  This hint is not guaranteed to be accurate but it
** is often close.  The underlying VFS might choose to preallocate database
** file space based on this hint in order to help writes to the database
** file run faster.
**
** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
** implements [sqlite3_deserialize()] to set an upper bound on the size
** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
** If the integer pointed to is negative, then it is filled in with the
** current limit.  Otherwise the limit is set to the larger of the value
** of the integer pointed to and the current database size.  The integer
** pointed to is set to the new limit.
**
** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
** extends and truncates the database file in chunks of a size specified
** by the user. The fourth argument to [sqlite3_file_control()] should 
** point to an integer (type int) containing the new chunk-size to use
** for the nominated database. Allocating database file space in large
** chunks (say 1MB at a time), may reduce file-system fragmentation and
