Allow mdb_env_set_mapsize() on an open environment

active in this process before resizing. This is slightly lighter
weight than doing a full env_close/env_open cycle.

mdb_txn_begin(): Clarify usage restrictions.

closing the handle could otherwise be read as happening even at failure.

There was little point in returning EINVAL when not: Comparing (A,B)
