* Timelock Recovery Extension
* Timelock Recovery Extension tests
* Use fee_policy instead of fee_est
Following 3f327eea07
* making tx with base_tx
Following ab14c3e138
* move plugin metadata from __init__.py to manifest.json
* removing json large indentation
* timelock recovery icon
* timelock recovery plugin: fix typos
* timelock recovery plugin: use menu instead of status bar.
The status bar should be used for displaying status. For example,
hardware wallet plugins use it because their connection status is
changing and needs to be displayed.
* timelock recovery plugin: ask for password only once
* timelock recovery plugin: ask whether to create cancellation tx in the initial window
* remove unnecessary code.
(calling run_hook from a plugin does not make sense)
* show alert and cancellation address at the end.
skip unnecessary dialog
* timelock recovery plugin: do not show transactions one by one.
Set the fee policy in the first dialog, and use the same fee
policy for all tx. We could add 3 sliders to this dialog, if
different fees are needed, but I think this really isn't
really necessary.
* simplify default_wallet for tests
All the lightning-related stuff is irrelevant for
this plugin.
Also use a different destination address
for the test recovery-plan (an address
that does not belong to the same wallet).
* Fee selection should be above fee calculation
also show fee calculation result with "fee: " label.
* hide Sign and Broadcast buttons during view
* recalculate cancellation transaction
The checkbox could be clicked after the fee rate
has been set. Calling update_transactions() may seem
inefficient, but it's the simplest way to avoid such edge-cases.
Also set the context's cancellation transaction to None when the
checkbox is unset.
* use context.cancellation_tx instead of checkbox value
context.cancellation_tx will be None iff the checkbox was unset
* hide cancellation address if not used
* init monospace font correctly
* timelock recovery plugin: add input info at signing time.
Fixes trezor exception: 'Missing previous tx'
* timelock recovery: remove unused parameters
* avoid saving the tx in a separate var
fixing the assertions
* avoid caching recovery & cancellation inputs
* timelock recovery: separate help window from agreement.
move agreement at the end of the flow, rephrase it
* do not cache alert_tx_outputs
* do not crash when not enough funds
not enough funds can happen
when multiple addresses are specified
in payto_e, with an amount larger
than the wallet has - so we set
the payto_e color to red.
It can also happen when the user
selects a really high fee, but this
is not common in a "recovery"
wallet with significant funds.
* If files not saved - ask before closing
* move the checkbox above the save buttons
people read the text from top to
bottom and may not understand
why the buttons are disabled

This module tries to restrict the ability of other processes to access the memory of our process.
Traditionally, on Linux, one process can access the memory of another arbitrary process
if both are running as the same user (uid). (Root can ofc access the memory of ~any process)
Programs can opt-out from this by setting `prctl(PR_SET_DUMPABLE, 0);`
also see https://man.archlinux.org/man/PR_SET_DUMPABLE.2const.en

Also, from https://unix.stackexchange.com/a/518452 :
In a terminal window:
```
% echo $$ # show our pid
6744
% read -sp 'secret password: '; echo
secret password:
%
```
Then in another terminal window:
```
% grep heap /proc/6744/maps
01bb7000-01c3e000 rw-p 00000000 00:00 0 [heap]
% dd if=/proc/6744/mem bs=1 skip=$((0x01bb7000)) count=$((0x01c3e000-0x01bb7000)) status=none |
strings | less
...
% dd if=/proc/6744/mem bs=1 skip=$((0x01bb7000)) count=$((0x01c3e000-0x01bb7000)) status=none |
strings | grep obiwan
obiwan_kenobi # "secret password"
```
The password should not be an empty string.

Accepting a PSBT opens the Tx dialog and pauses receiving additional PSBTs until the Tx dialog is closed.
Rejecting a PSBT will start a cooldown and accept all pending PSBTs into the history for later inspection.
