XMR compat: basic transaction support

- This functionality is work-in-progress: sweep transactions, spending to
  MMGen IDs and certain options are not supported yet.

- The `--autosign` option is required.  It may be set in the config file.

- On the offline signing machine, `--xmrwallet-compat` is required, or it
  may be set in the config file.  On the online machine, the option is
  required to permit interoperability with `mmgen-xmrwallet`.

- Note that transactions created with `mmgen-txcreate` must be sent with
  `mmgen-txsend`, not `mmgen-xmrwallet submit`, which looks for signed
  transactions in a different directory on the removable device.

- Signed or unsigned transactions may be aborted with `mmgen-txsend --abort`.

- Compat mode uses `mmgen-xmrwallet` as its backend, and that command is still
  required for all operations beyond simple create-sign-send to address.  For
  details, invoke `mmgen-xmrwallet --help`.

Sample workflow:

    $ mmgen-txcreate --coin=xmr XMR_ADDRESS,AMOUNT

    (remove - insert - wait for signing - remove - insert)

    $ mmgen-txsend

Testing/demo:

    $ test/cmdtest.py --coin=xmr -e xmr_compat
