cdc1f049bf Modify the interface to the blocking wal-checkpoint functionality.

a58f26f93f Add experimental command "PRAGMA wal_blocking_checkpoint", which uses the busy-handler to block until all readers have finished in order to ensure the next writer will be able to wrap around to the start of the log file.

9339da1f22 Rework the text to numeric conversion routines so that they work with either 
UTF8 or UTF16 and do not require a NULL terminator.  This allowed text to
numeric conversion without reallocating the string.

c6b2a0ff99 Change the journal_mode pragma to remove the "default journal mode" concept. 
The journal_mode pragma only effects currently attached databases and does 
not change the behavior of future attachments.

f6c614715c Make sure the schema is loaded before preparing a "PRAGMA journal_mode" command. This helps it return meaningful results when it is the first command executed by a new database connection.

3ebaee9633 The PRAGMA journal_mode=WAL; command now makes WAL the default journal mode 
for new databases added with ATTACH, so the behavior is consistent with the
other journal modes.
