48dc782ea6 ITS#7515 fix mdb_dbi_open/close
If a DBI handle is opened by a txn that aborts, the DBI handle
should no longer be valid.

53cf2eed90 ITS#7491 check for filled dirty page list
Very large single transactions will fail. It's not just a problem when
nested transactions are used. We could make this dynamically sized,
but I'm not sure what the point is.

If we're operating on the freelist, see if our current pghead

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.

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.

Wasn't pushing the optimal half of the array onto the stack,
thus used more stack than expected -> overrun.
