The lengths in the witness structure are `var_int` not pushes.
From BIP-141:
The `witness` is a serialization of all witness data of the transaction.
Each txin is associated with a witness field. A witness field starts
with a `var_int` to indicate the number of stack items for the txin. It is
followed by stack items, with each item starts with a `var_int` to
indicate the length. Witness data is NOT script.

Following changes were necessary outside the TREZOR plugin.
- transaction.py: update_transaction handles segwit transactions.
- keystore.py: added a segwit parameter to bip44_derivation,
use m/49' instead of m/44' for segwit.
