locale - let it check interactive-sections again (#937)
* locale - let it check interactive-sections again

* Turn Serial into a whole new screen

When in serial, first offer the rich/basic choice (or SSH button),
and only show the current welcome screen if we choose rich mode.
Add a back button on Welcome if we are on serial.

Michael Hudson-Doyle b0af11ad02 kill any foreground subprocess before restarting
This fixes a problem where you drop to a shell and refresh subiquity
from that shell -- the client tries to restart but it is running in the
background and so crashes trying to modify the terminal settings. So
this kills the subprocess before restarting. This required the extremely
angry PR I sent before: forcefully killing the subprocess also crashes
the client before restart in a similar way.

Michael Hudson-Doyle 939c81920c do not crash when subshell exits via signal
Here is something you can try with a live server installer today: drop
into a subshell and type "kill -9 $$". The installer will crash with an
'Input/output error' from tcsetattr.

What's going on is some deep unix arcana: when the subshell exits via
signal somehow the shell's process group is still in the foreground
(even though there are no processes in it?) and calling tcsetattr() from
a background process is not allowed. So the fix for this is reasonably
simple (or at least: short): call tcsetpgrp() to put our process group
back into the foreground. A background process doing this gets sent
SIGTTOU, but if we ignore that, all is well.

Frankly this is all very strange and I would like a lie down now.

Michael Hudson-Doyle 45009e3a12 refactor startup a little
the point of this is to have the event loop running while loading
autoinstall commands, which means we do not have to start and stop the
event loop inside load_autoinstall_config if there are early-commands to
run.
