ITS#7598 Tweak MDB_<NEXT/PREV>_NODUP,fix mdb_stat.
...
MDB_NEXT_NODUP, MDB_PREV_NODUP: Allow for non-MDB_DUPSORT databases.
No mdb.c code changes needed.
mdb_stat.c: Use MDB_NEXT_NODUP, to avoid a crash with a DUPSORT mainDB.

mdb_dcmp(): Assume the database has MDB_DUPSORT.
...
There was little point in returning EINVAL when not: Comparing (A,B)
and (B,A) would claim (A > B && B > A), which could confuse callers.

Check DB flags when refreshing a stale MDB DBI.
...
It's hairy to figure out when a DBI is valid. Catch destructive
user errors, and flags which another process changed under us.

ITS#7515 mdb_dbi_open(): Also open in parent txns.
...
This makes aborting nested and non-nested txns more
similar: The new DBI is available to the surrounding
context (parent txn and MDB_env respectively).

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.

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.

reside on a separate spindle.
