bbb2f5aa14 Comment why certain tests are disabled under TSAN
This makes it clear that it is due to a known limitation of TSan and not
some lurking thread safety issue.

Make fish_key_reader's output simpler (#8467)
* fish_key_reader: Simplify default output

It now only prints the bind statement. Timing information and such is
relegated to a separate "verbose" mode.

* Adjust fish_key_reader docs

* Adjust tests

8391f94081 Improve error for redirections to invalid paths
This finds the first broken component, to help people figure out where
they misspelt something.

E.g.

```
echo foo >/usr/lob/systemd/system/machines.target.wants/var-lib-machines.mount
```

will now show:

```
warning: Path '/usr/lob' does not exist
```

which would help with seeing that it should be "/usr/lib".

aa470e12b2 Defer escape bindings as well
This allows rebinding escape in the user list without breaking e.g.
arrow keys (which send escape and then `[A` and similar, so escape is
a prefix of them).

Fixes #8428.

9070ed8039 Correct the order of pkill arguments
On macOS, the tests would often fail because calls to `pkill` would "leak"
across tests: kill processes run by other tests. This is because on macOS,
the -P argument to pkill must come before the process name. On Linux it
doesn't matter.

This improves test reliability on Mac.

70e3e0beac Also remove ephemeral item if command is effectively empty
Fixes #8232.

Note that this needed to have expect_prompt used in the pexpect test -
we might want to add a "catchup" there so you can just ignore the
prompt counter for a bit and pick it back up later.

2ca66cff53 Disable job control inside command substitutions
This disables job control inside command substitutions. Prior to this
change, a cmdsub might get its own process group. This caused it to fail
to cancel loops properly. For example:

    while true ; echo (sleep 5) ; end

could not be control-C cancelled, because the signal would go to sleep,
and so the loop would continue on. The simplest way to fix this is to
match other shells and not use job control in cmdsubs.

Related is #1362

a32248277f Make commandline state thread safe
Today the reader exposes its internals directly, e.g. to the commandline
builtin. This is of course not thread safe. For example in concurrent
execution, running `commandline` twice in separate threads would cause a
race and likely a crash.

Fix this by factoring all the commandline state into a new type
'commandline_state_t'. Make it a singleton (there is only one command
line
after all) and protect it with a lock.

No user visible change here.

179073ce62 Clear the control-C cancel flag earlier, allowing event handlers to run
When the user presses control-C, fish marks a cancellation signal which
prevents fish script from running, allowing it to properly unwind.
Prior to this commit, the signal was cleared in the reader. However this
missed the case where a binding would set $fish_bind_mode which would
trigger event handlers: the event handlers would be skipped because of
the cancellation flag was still set. This is similar to #6937.

Let's clear the flag earlier, as soon as we it's set, in inputter_t.
Fixes #8125.

735105e33f bind tests: One more attempt to increase the timeouts
This is the last time I'm doing this before I rip these particular
tests out.

As far as I know there is no actual *problem* here, this is just
failing through a combination of macOS and Github Actions being slow
as molasses.

So it is wasting our time and therefore worse than not having these
tests at all, especially since they very rarely fail for good reasons.

We would leave some escape delay tests intact with generous timeouts, which would provide 90%
of the coverage with 10% of the hassle.

333032f626 tests: Increase how long exit_nohang tries
This runs in 100ms increments, so there's not a lot of harm in trying
longer - it should take the same time everywhere it succeeded before.

But I've reproduced failures on FreeBSD 13 on sr.ht, so there's at
least one platform where a total time of 1 second isn't enough.

Now we do 50 tries, which is 5 seconds.

ef96a6614b Update termsize before a sigwinch handler
This could have been one iteration off, e.g.

```fish
function on-winch --on-signal winch
    echo $LINES
end
```

Resize the terminal, it'll print e.g.

24

then run `echo $LINES` interactively, it might have a different answer.

This isn't beautiful, but it works. A better solution might be to make
the termsize vars electric and just always update them on read?

ed51e2baac Prevent hanging when restoring the foreground process group at exit
When fish starts, it notices which pgroup owns the tty, and then it
restores that pgroup's tty ownership when it exits. However if fish does
not own the tty, then (on Mac at least) the tcsetpgrp call triggers a
SIGSTOP and fish will hang while trying to exit.

The first change is to ignore SIGTTOU instead of defaulting it. This
prevents the hang; however it risks re-introducing #7060.

The second change somewhat mitigates the risk of the first: only do the
restore if the initial pgroup is different than fish's pgroup. This
prevents some useless calls which might potentially steal the tty from
another process (e.g. in #7060).

3cb105adbd Restore terminal modes after running key bindings with external commands
This concerns the behavior when running an external command from a key
binding. The history is:

Prior to 5f16a299a7, fish would run these external commands in shell
modes. This meant that fish would pick up any tty changes from external
commands (see #2114).

After 5f16a299a7, fish would save and restore its shell modes around
these external commands. This introduced a regression where anything the
user typed while a bound external command was executing would be echoed,
because external command mode has ECHO set in c_lflag. (This can be
reproed easily with `bind -q 'sleep 1'` and then pressing q and typing).
So 5f16a299a7 was reverted in fd9355966.

This commit partially reverts fd9355966. It has it both ways: external
commands are launched with shell modes, but/and shell modes are restored
after the external command completes. This allows commands to muck with
the tty, as long as they can handle getting shell modes; but it does not
enable ECHO mode so it fixes the regression found in #7770.

Fixes #7770. Fixes #2114 (for the third time!)

This partially reverts commit fd9355966e.

fd9355966e Stop donating the terminal for bind functions
Unfortunately this causes input coming in while bind functions are
running to show up on screen.

Since the cure is worse than the disease let's just stop doing it.

My guess is this needs to *only* be done while running an external
command.

4762d52e52 output: A background is set if it's not a special non-color
For reasons unclear to me, fish enables bold mode unconditionally if
the background is set.

However, this called a background "set" if it wasn't exactly the
"normal" color, whereas set_color --print-colors would set a color
of *none*.

We have three special non-color colors:

- "normal"
- "reset"
- "none"

All of these specify some form of absence of background color, so all
of them should be checked.

This fails on FreeBSD on sr.ht and NetBSD on my own VM, but it works manually.

I *know* this is a bit of a long line. I would still quite like having
