On a cleanly wiped device, storage must be unlocked in order to create
and retrieve the serial number. However, storage unlocking happens in
boot.py, which is imported _after_ usb.py
We must therefore sidestep asking for the serial number.

The goal is to allow Trezor 1 to create TPoS contracts for Stakenet.
Last year, Stakenet introduced a hard-fork [1] to change the way TPoS contracts
are created, instead of a custom signature method, now it works with the
output from the signMessage method, while this works for Trezor T, it doesn't
work for Trezor 1 due to the 80 bytes limit on the OP_RETURN output while
Stakenet allows up to 150 bytes [2], in a gitter discussion [3] we concluded that
the change should be fine.
The hard-fork was introduced because we couldn't got our TPoS contracts PR accepted [4],
the OP_RETURN still contains the same data, its just stored in a different way:
- The TPoS address, where the coins to stake are stored, and where rewards are received.
- The merchant address, where the merchant receives its commission.
- The contract commission.
- The TPoS collateral signature (this is what uses the signMessage now).
At last, there is an example transaction creating a TPoS contract [5].
