648e264342 Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS 
value for sqlite3_db_status().  This is a cherry-pick of a sequence of five
checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70].

9b4c59fa1b Refactoring the mmap interface. The controlling pragma is now "mmap_size" 
instead of "mmap_limit".  Also change SQLITE_CONFIG_MMAP_LIMIT and
SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and
SQLITE_FCNTL_MMAP_SIZE, respecctively.  
The default mmap_size is now always 0, meaning that
memory mapped I/O is off by default.  There is a new compile-time option
SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size.
Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic
and causes it to be omitted from the build.  An extra argument is added
to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE
at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we 
know that it does not work, meaning that it cannot be turned on by mistake
on those platforms.

files and changes the default for any future databases that might be added
using ATTACH.

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

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.
