this involves some changes to the workflow defaults:
* workflow.start_default() takes no arguments
* workflow.set_default() (originally replace_default) configures the
default that will be started by next call to start_default().
The intended usecase is to set_default() first and then start it
separately.
* apps.base.set_homescreen() factors out the logic originally in
main.py, that decides which homescreen should be launched. This uses
set_default() call. start_default() is then used explicitly in main.py
also refactor show_pin_invalid and its usages so that it raises directly
note that we are now using PinCancelled instead of ActionCancelled where
appropriate
- core/bitcoin: move common files to the app's root
- core/bitcoin: use require_confirm instead of confirm
- core: move bitcoin unrelated functions from 'bitcoin' to a new 'misc' app
- core/bitcoin: use relative imports inside the app
- core: rename wallet app to bitcoin
- core/wallet: replace SigningErrors and the other exception classes with wire.Errors
- CLSAG signature scheme added
- type hints added
xmr: optimize protocol, send only required data
- real_out_additional_tx_keys contains only one element as nothing more is needed during signature
- only src_entr.outputs[index] is HMACed and always present. Other outputs are present only if needed which reduces comm and CPU overhead.
- getting rid of subaddresses dictionary (memory requirements), now subaddr indices are present per source entry so keys are computed when needed
xmr: prepare for permutation sending removal, specify index
- specify source entry ordering index prior sorting by key images as original HMAC keys are generated based on these.
- permutation checked just by valid HMACs, size of the set, key image sort order
- sending permutation is now deprecated, will be removed in the following protocol versions
- more strict state transition checks, guard strict check with respect to steps ordering
