7c6433cfff When inserting a 3-byte cell into a btree, ensure that the extra padding byte 
is 0x00.  This is not necessary for security, as far as I can tell, but it
seems like a reasonable precaution.

68d92c4ad3 Enhancements to PRAGMA optimize and ANALYZE. Add the 0x10000 flag to 
PRAGMA optimize.  ANALYZE now records zero-size partial indexes in the
sqlite_stat1 table.  PRAGMA optimize looks for both growth and shrinkage
in table sizes, and uses tighter bounds (10x rather than 25x) to trigger
a re-analyze.  PRAGMA optimize automatically uses are reasonable
analysis_limit to prevent excessive runtimes.
