of the internal query planner data structures.

This check-in compiles but does not work. The test suite gets incorrect
answers and crashes.

there is always at least one compilation option.

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.

ORDER BY clause, AS names take priority over any column names.
Candidate fix for ticket [2500cdb9be].

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.

is free to ignore that hint if desired. However, if "PRAGMA mmap_limit(0)"
is used, xFetch is never called.

exist, rather than the old behavior of manifesting the parenthesized table
into a transient table. Also, tag every FROM-clause SELECT subquery that is
generated by a parenthesized FROM-clause expression using the SF_NestedFrom
flag. The new SF_NestedFrom flag is not yet used for anything.

This fixes the test script "shared9.test", though there is still a memory leak.
And there are other problems. Consider this a work-in-progress.
