Move session timeout from wallet to config
Prevent timeouts whenever a device operation is in progress
Move timeout job from each plugin to device manager
Break out the workflow logic of the install wizard
into a base class. This means reimplementing with
full support in a new GUI is now easy; you just provide
ways to request passwords, show messages etc. The API
is fully documented in the base class.
There are a couple of minor outstanding issues, including that
the old messages shown when recovering a wallet are missing.
I will come back to that. Ledger wallet might be broken.
Other improvements:
The install wizard code is now easy to follow and understand.
Hardware wallets can now be restored without any need for their
accompanying libraries.
Various bits of trustedcoin were broken and have been fixed.
Many plugin hooks can be removed. I have only started on this.
SimpleConfig claims to handle configuration options in priority
command line, user config, system config, which makes sense.
In fact it appears it used priority command line, system config,
user config.
Also, from the priority ordering, it would seem correct that a
value should be unmodifiable if and only if it's set on the command
line. Previously anything in the system config would be unmodifiable.
This patch fixes these and cleans the code up a bit. I noticed this
whilst attempting to unify the 'auto_cycle' setting.
Fixup tests accordingly.
We store it in the config object instead of in the blockchain object.
The blockchain object now refers to its config, and calls refresh_height() to update it.
The network objects also refer to the config rather than the blockchain.
This is the first of many small steps to untangle the verifier from stored state and so
permit the history tab to work in offline mode. The refactoring will simultaneously clean
up a lot of accumulated cruft.
