A small fixed list of modules is kept pre-loaded in the GC arena.
These must not keep references to anything else, as all other modules
are unloaded and the memory is cleared.
apps.webauthn.boot() does not need an if-condition because it's only
called from session.py when the usb interface is enabled
This means that they do not need to be stored in RAM at all. The obvious
drawback is that we need to hand-edit the if/elif sequence, but we don't
register new handlers all that often so 🤷
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].
