Since we enable/disable terminal protocols whenever we pass terminal ownership,
tests can no longer run in parallel on the same terminal.
For the same reason, readline shortcuts in the gdb REPL will not work anymore.
As a remedy, use gdbserver, or lobby for CSI u support in libreadline.
Add sleep to some tests, otherwise they fall (both in CI and locally).
There are two weird failures on FreeBSD remaining, disable them for now

Design and implementation borrows heavily from Kakoune.
In future, we should try to implement more of the kitty progressive
enhancements.
Closes#10359
Instead of trying to assert that there are no zombies when the test
starts (which often fails) and to prevent conflating existing or
irrelevant zombies with the ones we are interested in checking for,
have `ps` also emit the parent process id and filter its output to
include only children of the current fish instance.
Now that `$last_pid` is never fish's pid, we no longer need to force
jobs to run in their own pgroup. Restore the job control behavior to
what it was prior, so that signals may be delivered properly in
non-interactive mode.
This reverts commit 3255999794
Prior to this change, a function with an on-job-exit event handler must be
added with the pgid of the job. But sometimes the pgid of the job is fish
itself (if job control is disabled) and the previous commit made last_pid
an actual pid from the job, instead of its pgroup.
Switch on-job-exit to accept any pid from the job (except fish itself).
This allows it to be used directly with $last_pid, except that it now
works if job control is off. This is implemented by "resolving" the pid to
the internal job id at the point the event handler is added.
Also switch to passing the last pid of the job, rather than its pgroup.
This aligns better with $last_pid.
We have no idea why this was even a thing. For now simply set it to
"all"/"full" (why these two names? no idea) at startup and allow
changing it later.
Settting it *immediately* when defining the variable sets it too soon
because we don't have the interactive signal handlers
enabled (including the one for SIGTTOU), so let's first settle for
this little piece of awkwardness.
This needs widespread testing, so we merge it early, immediately after
the release.

(and probably numerous others)
This one sometimes fails with a zombie detected, so I'm assuming it's
too fast for reaping to happen, so we add another 100ms sleep.
Yeah, this isn't great but...eh
This allows code of the form `if jobs -q $some_pid` in scripts to check whether a previously started job is still running. Previously this would return the correct value, but also print an error message.
The invalid argument errors will still be printed.
Added test cases for both.
