This removes the need to run c-compilation on one file, and allows us
to in future c++-ify this a bit.
There's a lot of bit-fiddling here that is quite unnecessary, better
error-handling would be nice...
So far this removes a few more unused things (because I would have had
to port them), including:
- Functions with ARITY > 3 (even 3 isn't used, but just so we don't
get complacent)
- Variables
- Most functions moved out of the header, because only te_interp is used.
- The te_print function
The function `add_disowned_pgid` adds process *group* ids and not
process ids. It multiplies the value by negative 1 to indicate a wait
on a process group, so the original value must be positive.
If a job is disowned that, for some reason, has a pgid that is special
to waitpid, like 0 (process with pgid of the calling process), -1 (any
process), or our actual pgid, that would lead to us waiting for too
many processes when we later try to reap the disowned processes (to
stop zombies from appearing).
And that means we'd snag away the processes we actually do want to
wait for, which would end with us in a waiting loop.
This is tough to reproduce, the easiest I've found was
fish -ic 'sleep 5 &; disown; set -g __fish_git_prompt_showupstream auto; __fish_git_prompt'
in a git repo.
What we do is to not allow special pgids in the disowned_pids list.
That means we might leave a zombie around (though we probably wait on
0 somewhere), but that's preferable to infinitely looping.
See #5426.
* Severely extended the sorin theme
This theme should now mostly match the original.
* Removed superfluous whitespace
* Inlined external links as ASCII art
* Made myself the author of the sorin theme
* Removed superfluous read delemiter
* Renamed __fish_git_action to fish_print_git_action
* Adde a minor comment
Return STATUS_INVALID_ARGS when failing due to evaluation errors,
so we can tell the difference between an error and falseness.
Add a test for the ERANGE error
The rest of the high-numbered exit codes are not values used by scripts
or builtins, they are internal to fish and come out of
the parser for example.
Prior to adding STATUS_INVALID_ARGS, builtins were usually exiting 2
if they had a special exit status for the situation of bad arguments.
Set it to 2.
We were not parsing an in-range number when we claimed we were,
and were thus failing to error with invalid numbers and returned
a wrong test result. Fixed#5414
Also, provide the detail we can for the other error cases.

Cleaned up the code to no longer replicate in fishscript what fish
already does (and caches to boot) in C++ in setting up the paths to the
user configuration directory.
Also introduced a `$__fish_user_data_dir` instead of the sporadic
definitions of `$userdatadir` that may or may not go through
`XDG_DATA_HOME`.

I spent some time figuring out $TERM_PROGRAM_VERSION and Terminal.app's
capabilities over time. [1]
Only use OSC 7 if running on the version of Terminal.app that added it
or newer. In the past this would have been harder because `test` couldn't
do float comparisons.
cleanup:
Don't bother setting a local $TERM_PROGRAM if it's unset: quoting
is enough to keep test happy. For the version numbers, 0"$var" is safe
against unset variables for numerical comparisons.

Instead of maybe adding "-s" and "-M" if "-s" hasn't already been
given, just add "-s" to _every_ bind invocation, and "-M" to those who
need it.
Fixes#5028.
Largely reverts 007d794b6e.
fish_indent is extremely resource-intensive on large inputs and can crash; it also does not handle
invalid characters gracefully.
Work on #5402.
Just sets locale to "C" (because that's the only one we need), does
wcstod and resets the locale.
No idea why uselocale(loc) failed for me, but it did.
Fixes#5407.
This previously used /dev/tty to make sure we have `source` connected
to a terminal. Only as it turns out, FreeBSD doesn't have that (https://builds.sr.ht/~faho/job/15308).
So instead, let's just use the expect tests since stdin there is by
definition a terminal.
