I'm writing from scratch a wrapper of LMDB for the Perl language, the project is
progressing fast and looks very promising. Thank you for a wonderful library!

I want to avoid as much as possible the need to duplicate LMDB's state in perl,
in particular dbi's flags, so I need a method to obtain the MDB_env from a
MDB_txn, but the required API is missing.

In the same spirit of mdb_cursor_txn or mdb_cursor_dbi I propose adding
mdb_txn_env.

Provided a patch against gitorious mdb.master.

Any comments or questions more than welcome.

Regards.

Salvador
