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.

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.

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.

ITS#7364 Always sem_unlink() in mdb_env_open().

Drop the sem_unlink() error checks, which could prevent the 2nd
unlink. Instead use O_EXCL in sem_open().
This makes "open+close the database" the API for trying to clean
away the old semaphores, if they were left behind by a previous run.
