afdc9e23fc In FTS3, avoid calling memcpy() with a NULL source pointer, even if the 
transfer amount is zero bytes.

eab0e10304 In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound 
to persistent SQL statements using SQLITE_STATIC, the binding is replaced with
an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer
to the persistent statement using sqlite3_next_stmt() and attempt to access
the freed buffer using sqlite3_expanded_sql() or similar.

57ebc84a6e Fix a problem in fts3/4 that was causing it to discard data cached in-memory if an 'optimize' command is run when there is no data on disk. The usual way this would happen is if the very first transaction that writes to the fts3/4 table also includes an 'optimize' command.

b46ee91729 Allow the "order=DESC" and "order=ASC" parameters in FTS4 "CREATE VIRTUAL TABLE" statements. Tables created with "order=DESC" store all doclists in descending order, which allows optimizations normally applied to "ORDER BY docid ASC" queries to be used with "ORDER BY docid DESC" queries instead.
