Fix checking change address
...
There was a signed/unsigned problem: size_t is unsigned, but we use
-1 to indicate mismatch. The problem was that when checking the input
address path, it still did this unintentionally when a mismatch was
detected, forbidding to sign with mismatched inputs, even when there
is no change address.
We now use 1 for mismatch. Also we don't allow change address anymore
if the inputs have a path of length 1. This simplifies the code a bit.

No quadratic hashing for hardfork
...
Don't hash the whole transaction if forkid is set. Instead use the
same codepath as for segwit.
Rename segwit_to_spend to authorized_amount and use it for forkid
amount and segwit amount validity checks.
Removed some duplicated code.

Faster signing, smoother progressbar.
...
Most time in signing transaction on the Trezor side is spent
in layoutProgress. This patch reduces the calls to this functions.
We also compute the progress differently, reserving 50 % for downloading
input transactions and 50 % for the signing process. This gives a
smoother experience if the input transactions are large.
