9ca95730e3 Add the SQLITE_ENABLE_API_ARMOR compile-time option. This is a work in 
progress and is not yet completely functional.

6cf4a7dfa6 Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the 
P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose
record header cache is to be cleared.  This gives a small size reduction
and performance increase.

75b170b164 Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes 
the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine
has a chance to run.  Since the aiRowEst now might be deleted from freeIndex()
which does not always have a db pointer, make sure the aiRowEst memory is
not held in lookaside.

7ea31ccb01 Since numeric affinity is the most common case, check it first. Interchange

b2445d5ee8 Move user authentication blocking from sqlite3_prepare() over to the 
table lock generator, thus allowing SQL statements (like 
"PRAGMA locking_mode") that do not touch database content to run
prior to authentication.

using bad credentials.  The extension is now feature complete, but much
testing and bug-fixing remains.
