7efa426ee9 Make sure the sqlite3BtreeCount() routine does not leave index cursors in an 
inconsistent state, as doing so might result in an assertion fault inside
of sqlite3BtreeKey() called from saveAllCursors() if content is deleted out
from under the statement that issued the sqlite3BtreeCount() call.

18b67f3f0d Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides 
minimal performance improvements, and then only at SQL preparation time, not
at runtime, and it has problems with data races in shared-cache mode.  We might
later add the keyinfo cache back but only enable it when shared-cache mode
is off.

answer for the "rowid" column in a WITHOUT ROWID table.  Enhance it so that
it can be used to check for the existence of a table by setting the column
name parameter to NULL.  The routine is now included in the build by
default, even without the SQLITE_ENABLE_COLUMN_METADATA compile-time option.
