41aab89b31 Faster keywordCode() implementation by taking advantage of the fact that 
the input is always pure ASCII alphabetic and underscore and that the keyword
table is always upper-case.

8974331fc3 Demonstrate a much faster sqlite3GetToken() routine by using a lookup table 
to map initial token characters into a character class.  This check-in does
not work for EBCDIC.  More optimization needed.

found.  Also fix a bug that this utility detected as it was being tested.

6d258995e6 Refinements to synchronous logic:

(4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal
unlink are off by default.
