2d6e34c8c2 ecc: make ECPubkey.__lt__ relation strongly-connected/total 
Previously we had:
```
>>> import electrum
>>> from electrum.ecc import POINT_AT_INFINITY
>>> G = electrum.ecc.GENERATOR
>>> G <= (-1 * G)
False
>>> (-1 * G) <= G
False
```

376fc01b27 keystore.sign_message: add optional script_type argument 
this is used by trezor
(and also by bitbox02, which was using a workaround previously)

5cdb4471ec signmessage: also accept Trezor-type sigs for p2wpkh and p2wpkh-p2sh addrs 
The signatures we create are unchanged but we now also accept signatures created by Trezor and others.

instead of raising Exceptions on bad signatures.

b14747ecfe ecc.ECPubkey: add custom __deepcopy__ implementation 
With python-ecdsa 0.15, copy.deepcopy(ecdsa.ecdsa.Public_key) started to raise.
This fixes the Travis test failures.

Also rm unused ECPrivkey._privkey attribute.

5b88b8667e also grind ecdsa low R when using libsecp256k1, and fix tests 
note: low R grinding would not have to be duplicated if we trusted the caller
to have done it already (as is the case with the classes in ecc.py), and if
we propagated the choice of "random_k" as part of the nonce_function passed
to libsecp256k1 (which is not currently done)
