unportable and highly deprecated <malloc.h> header on all platforms
except Apple Mac OS X. The <malloc.h> actually is never required on
any OS with an at least partly POSIX-conforming API as the malloc(3) &
friends functions officially live in <stdlib.h> since over 10 years.
Under some platform like FreeBSD the inclusion of <malloc.h> since a few
years even causes an "#error" and this way a build failure. So, just get
rid of the bad <malloc.h> usage in FTS1 and FTS2 extensions at all and
stick with <stdlib.h> there only. (CVS 4191)

modified fts2:
Modify handling of SQLITE_SCHEMA in fts2 code. An SQLITE_SCHEMA error
may cause SQLite to reload the internal schema, deleting and
recreating v-table objects. So the sqlite3_vtab structure can be
deleted out from under a v-table implementation. (CVS 4183)

them as the code rots. (CVS 3693)

When creating fts tables in an attached database, the backing tables
are created in database 'main'. This change propagates the
appropriate database name to the routines which build sql statements.
Note that I propagate the database name and table name separately. I
briefly considered just making the table name be "db.table", but it
didn't fit so well in the model used to store the table name and other
information, and having the db name passed separately seemed a bit
more transparent. (CVS 3631)

Calling UPDATE against an fts table in a UTF-16 database inserts
corrupted data into the database. The UTF-8 data is being inserted
directly. This appears to happen because sqlite3_ value_text()
destructively coerces a value to UTF-8, and it's never converted back
when updating the table. This works around the problem by rearranging
things so that the update happens before the coercion. (CVS 3596)

The virtual table interface allows for a cursor to field multiple
xFilter() calls. For instance, if a join is done with a virtual
table, there could be a call for each row which potentially matches.
Unfortunately, fulltextFilter() assumes that it has a fresh cursor,
and overwrites a prepared statement and a malloc'ed pointer, resulting
in unfinalized statements and a memory leak.
This change hacks the code to manually clean up offending items in
fulltextFilter(), emphasis on "hacks", since it's a fragile fix
insofar as future additions to fulltext_cursor could continue to have
the problem. (CVS 3521)

docListRestrictColumn() generates a DL_POSITIONS doclist, which means
that after the first doclist is processed, the second doclist is
initialized as DL_POSITIONS, but with DL_POSITIONS_OFFSETS data.
(Note that DL_DEFAULT is now DL_POSITIONS, which masks this bug.) (CVS 3467)

We handle an UPDATE to a row by performing an UPDATE on the content table and by building new position lists for each term which appears in either the old or new versions of the row. We write these position lists all at once; this is presumably more efficient than a delete followed by an insert (which would first write empty position lists, then new position lists). (CVS 3434)
