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.

ends. Cursors in parent transactions are updated when their child
transaction commits.
