Allow mdb_env_set_mapsize() on an open environment

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)

Very large single transactions will fail. It's not just a problem when
