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.

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.

clauses that span multiple tables in a join.

index in general and for joins. Use macros to test for bits in the
disabled-optimization bit vector, in order to make the code clearer.

sqlite3_busy_timeout() interfaces for programmers that are working from

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.

that have shared-cache enabled but also use :memory: databases which they
expect to keep separate.

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.

causes separate shared-cache connections in read_uncommitted mode to abort as
well.
