188d488409 Disable the use of memory-mapped I/O if the SQLITE_DISABLE_MMAP macro is 
defined.  Automatically define this macro for OpenBSD and QNX.  Other
systems are likely to be added to the disabled list over time.

34f7490311 Change the mmap_limit pragma to report the new limit, or to report the 
existing limit if called with no arguments.  Report the default mmap_limit
as part of PRAGMA compile_options.  Set the default mmmap_limit to 0 for
all systems other than linux, mac, windows, and solaris.

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.

0d0614bdc6 Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be 
used to issue a hint to the VFS to limit mmap space to N bytes.  The VFS
is free to ignore that hint if desired.  However, if "PRAGMA mmap_limit(0)"
is used, xFetch is never called.

e096205a7f New debugging pragmas: PRAGMA vdbe_debug=ON is short-hand for the sql_trace, 
vdbe_listing, and vdbe_trace pragmas.  PRAGMA vdbe_debug enables tracing of
sqlite3VdbeAddOp() calls.  None of this is active unless compiled with
SQLITE_DEBUG.

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.
