Upfront shutdown script is a script provided on channel opening,
which will be used by the peer to enforce us closing to this script
on collaborative channel close.
before:
node_id -> set of (host, port, ts)
after:
node_id -> NetAddress -> timestamp
Look at e.g. add_recent_peer; we only want to store
the last connection time, not all of them.
Re total runtime of WalletDB.write() and file size on disk,
for a large encrypted wallet, compare:
before (zlib level=6):
file size 16_670 KB
JsonDB.dump 0.5099 sec
zlib.compress 1.3280 sec
ECPubkey.encrypt_message 0.1720 sec
after change (zlib level=1):
file size 17_527 KB
JsonDB.dump 0.5344 sec
zlib.compress 0.5320 sec
ECPubkey.encrypt_message 0.1837 sec
The standard json module has an optimized C encoder, but that doesn't
currently support indentation. So if you request indentation, it falls
back on the slower Python encoder.
Readability doesn't matter for encrypted wallets, so this disables
indentation when the wallet is encrypted.

dnspython changed the overall timeout for a request from 30 sec to 5 sec in version 2.0
(see 7ed1648b84 )
5 seconds is not enough in some network conditions...
We manually set the timeout back to 30 sec.
Note that in case these dns hacks are applied, and the timeout is reached,
we fallback to the system dns resolver, which hopefully can get a response.

Sometimes we want its "remember path" behaviour but it does not make sense to
parent the dialog from main window. When so, caller code no longer needs to
get a reference to a main window.
Also rm last usages of get_parent_main_window().
this fixes running with --offline:
