a1f42c7c32 Add the SQLITE_CONFIG_MMAP_LIMIT configuration option for overriding the 
SQLITE_DEFAULT_MMAP_LIMIT compile-time setting.  Enhance "PRAGMA mmap_limit"
so that without a specific database name, it sets the limit on all database
files and changes the default for any future databases that might be added
using ATTACH.

disabled-optimization bit vector, in order to make the code clearer.

167cd6ab78 Revert sqlite3_close() to legacy behavior. Create a new sqlite3_close_v2() 
interface that exhibits the deferred-close behavior.  This minimizes the
chance of breakage in legacy apps.

4245c405ea The sqlite3_close() interface returns SQLITE_OK even if there are outstanding 
sqlite3_stmt and sqlite3_backup objects.  The connection becomes a zombie.
Resource deallocation is deferred until the last sqlite3_stmt or 
sqlite3_backup object closes.  This is intended to help SQLite play nicer
with garbage collectors.

81028a455d The former sqlite3ResetInternalSchema() routine was really two different 
routines, selected by parameter, each with a confused mission.  So split
this routine up into three separate smaller routines, calling each
separately as needed.  Hopefully this will make further refactoring and
schema reset collateral damage containment easier.
