dan 2e6ca188c4 Fix a buffer overwrite in fts5 that could occur when processing a prefix 
query.

FossilOrigin-Name: 92fc146bc2b781e7e2d7138b00e5ea649c6fee1c2b8449420460a1b3e5c9661b

drh 2c2f392dca Add interfaces sqlite3_prepare_v3() and sqlite3_prepare16_v3() with the 
extra prepFlags argument.  Add the SQLITE_PREPARE_PERSISTENT option as one
bit in that argument.

dan 6b4fbabd6a Do not save the state of an fts5 merge operation mid-way through an input 
term, even if no previous entry for that term has caused any output. Doing so
may corrupt the FTS index.

dan be0bc8bb4d Have fts5 close any open blob-handle when a new savepoint is opened. This 
ensures that fts5 does not prevent DROP TABLE statements (which always open a
savepoint) from succeeding.
