** FTS3 used to optionally store character offsets using a compile-time
** option.  But that functionality is no longer supported.
**
** A doclist is stored like this:
**
** array {
**   varint docid;
**   array {                (position list for column 0)
**     varint position;     (2 more than the delta from previous position)
**   }
**   array {
**     varint POS_COLUMN;   (marks start of position list for new column)
**     varint column;       (index of new column)
**     array {
................................................................................
**   value:     123 5 9 1 1 14 35 0 234 72 0
**
** The 123 value is the first docid.  For column zero in this document
** there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
** at D signals the start of a new column; the 1 at E indicates that the
** new column is column number 1.  There are two positions at 12 and 45
** (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
** 234 at I is the next docid.  It has one position 72 (72-2) and then
** terminates with the 0 at K.
**
** A "position-list" is the list of positions for multiple columns for
** a single docid.  A "column-list" is the set of positions for a single
** column.  Hence, a position-list consists of one or more column-lists,
** a document record consists of a docid followed by a position-list and
** a doclist consists of one or more document records.

** FTS3 used to optionally store character offsets using a compile-time
** option.  But that functionality is no longer supported.
**
** A doclist is stored like this:
**
** array {
**   varint docid;          (delta from previous doclist)
**   array {                (position list for column 0)
**     varint position;     (2 more than the delta from previous position)
**   }
**   array {
**     varint POS_COLUMN;   (marks start of position list for new column)
**     varint column;       (index of new column)
**     array {
................................................................................
**   value:     123 5 9 1 1 14 35 0 234 72 0
**
** The 123 value is the first docid.  For column zero in this document
** there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
** at D signals the start of a new column; the 1 at E indicates that the
** new column is column number 1.  There are two positions at 12 and 45
** (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
** 234 at I is the delta to next docid (357).  It has one position 70
** (72-2) and then terminates with the 0 at K.
**
** A "position-list" is the list of positions for multiple columns for
** a single docid.  A "column-list" is the set of positions for a single
** column.  Hence, a position-list consists of one or more column-lists,
** a document record consists of a docid followed by a position-list and
** a doclist consists of one or more document records.

**
** The integrity-check works as follows. For each token and indexed token

** in fts3ChecksumEntry()) based on the following:
**
**     + The index number (0 for the main index, 1 for the first prefix

**     + The docid of the row it appears in,
**     + The column it appears in, and
**     + The tokens position within that column.
**
** The checksums for all entries in the index are XORed together to create
** a single checksum for the entire index.
**
** The integrity-check code calculates the same checksum in two ways:
**
**     1. By scanning the contents of the FTS index, and 
**     2. By scanning and tokenizing the content table.
**
** If the two checksums are identical, the integrity-check is deemed to have
