Allow both increasing and decreasing the environment size.
But don't allow decreasing below the currently occupied space.

aff2693fc0 ITS#7455 simplify
Don't try to reclaim overflow pages while operating on
the freelist (for now). The circular dependencies are much like
the single-page case, but worse. Maybe look into this in the
future, but it's not absolutely necessary now.

Keep list sorted if it grows during a write. Don't free pghead until
we're sure our writes are all finished.

97ed96206d mdb_env_sync(,force=1): Override MDB_MAPASYNC.
With MDB_MAPASYNC, the API provided no way to ensure full sync.

b9275c9991 mdb_cursor_dbi(): Assume valid args.
It returned 0, which is the freelist DBI and is valid for a few uses.

7e620a34a2 API change: mdb_drop() only accepts del=0 or 1.

d903bed218 API change: mdb_env_set_maxdbs(, *named* DBs).
Let the user specify the number of databases he will actually
use. Adding 2 for FREE_DBI and MAIN_DBI is an internal matter.

6b56e0fab1 ITS#7453 Fix reset of MDB_NOSYNC/MDB_NOMETASYNC.
mdb_env_open() with these flags did not open a synchronizing
file descriptor.  Thus disabling them later did not work.

0201b9002c Tweak MDB_FIXEDMAP handling.
Drop mmap()'s MAP_FIXED flag, so it returns another address instead
of unmapping existing overlapping pages. Verify the returned address.

52e3adbdec Renumber MDB_NOSUBDIR. Check mdb_env_open() flags.
MDB_NOSUBDIR was == MDB_REVERSEKEY. That affected the freelist:
Env flags are stored in mm_flags alias mm_dbs[FREE_DBI].md_flags.

It stays a persistent flag, in case mdb_env_open someday wants
to pick/verify which lockfile to use with the datafile.

Catch bad flags so they will no longer make it into the data file.

bb36bdcd1c ITS#7432 fix typo in mdb_midl_sort
Wasn't pushing the optimal half of the array onto the stack,
thus used more stack than expected -> overrun.
