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.

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.
