Allow mdb_env_set_mapsize() on an open environment

The caller is responsible for making sure no transactions are
active in this process before resizing. This is slightly lighter
weight than doing a full env_close/env_open cycle.

Clarify doc: mdb_copy, nested txns, mdb_drop().
...
mdb_copy: Does not copy lockfile. Can trigger file growth.
mdb_txn_begin(): Clarify usage restrictions.
mdb_drop(): State what to do rather than what will be done, since
closing the handle could otherwise be read as happening even at failure.

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.

This makes aborting nested and non-nested txns more
similar: The new DBI is available to the surrounding

Very large single transactions will fail. It's not just a problem when
nested transactions are used. We could make this dynamically sized,

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.
