30a37d9433 abbr: Make show output actually work
This would print

```
abbr -a -- dotdot --regex ^\\.\\.+\$ --function multicd
```

which expands "dotdot" to "--regex ^\\.\\.+\$...".

Instead, we move the name to right before the replacement, and move
the `--` before that:

```
abbr -a --regex ^\\.\\.+\$ --function -- dotdot multicd
```

It might be possible to improve that, but this at least round-trips.

9790907ca8 abbr: stop parsing option after first expansion token
Historical behavior is to stop option parsing at the first non-option argument.
Since we have added more options, it seemed impractical to keep that behavior.

However people are using options in their abbr expansions ("abbr e emacs
-nw").  To support this, we ignore options. However, we only ignore them
if they are not valid "abbr" options.  Let's ignore all options in the
expansion definition, which is a small price to pay to keep most existing
configurations working.

Fixes #9410

This does not fix other cases which used to work, like

    abbr x -unknown

Those are hopefully not used by anyone, so I don't think we need to maintain
support for that.

35a4688650 Rename abbreviation triggers
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.

7118cb1ae1 Implement set-cursor for abbreviations
set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:

    abbr L! --position anywhere --set-cursor ! "! | less"

and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.

1402bae7f4 Re-implement abbreviations as a built-in
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.

Re-implement abbreviations using a builtin, managing them internally.

Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.

Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.

d2daa921e9 Introduce re::make_anchored
This allows adjusting a pattern string so that it matches an entire
string, by wrapping the regex in a group like ^(?:...)$

This is a workaround for the fact that PCRE2_ENDANCHORED is unavailable
on PCRE2 prior to 2017, so we have to adjust the pattern instead.

Also introduce an overload of match() which creates its own
match_data_t.

892a820672 Make sure that cd to a relative CDPATH results in absolute $PWD
We have had multiple crashes for relative CDPATH entries.  Commit 5e274066e
(Always return absolute path in path_get_cdpath, 2019-10-17) tried to fix
all of them but it failed to do justice to its title.  Let's fix this to
actually return absolute paths, always.  Take care to to normalize the path
because it is used for autosuggestions. The normalization is mostly relevant
for CDPATH=. (the default) but it doesn't hurt others.

063450b8f4 Update likely/unlikely macros to avoid double negation
I believe this should be identical to the previous code and handle the same
cases (I'm guessing going by the comment that this came from a C codebase
without `bool` types).

The problem with the previous code is that it tripped up the `clangd` analyzer
into thinking `assert()` expressions can/should be simplified via DeMorgan's to
improve readability (because it was seeing the fully expanded macro).

7ee161af8d Fix the flaky tty_ownership test on Mac
The tty_ownership test was sometimes failing. In this test,
`fish_test_helper` creates a child and transfers the tty to it,
"abandoning" the tty. In some cases, the child was running before the
parent; the child claims the tty. When the parent tries to transfer it to
the child, it get SIGTTIN and stops. Fix this by ignoring SIGTTIN and
SIGTTOU.

This only affects macOS and BSDs.

c4a60feff1 Stop attempting to complete inside comments
Inside a comment we offer plain file completions (or command completions if
the comment is in command position). However these completions are broken
because they don't consider any of the surrounding characters. For example
with a command line

    echo # comment
              ^ cursor

we suggest file completions and insert them as

    echo # comsomefile ment

Providing completions inside comments does not seem useful and it can be
misleading. Let's remove the completions; this should communicate better that
we are in a free-form comment that's not subject to fish syntax.

4cb19e244b Sort and deduplicate output of complete -C
This addresses a long-standing TODO where `complete -C` output isn't
deduplicated.

With this patch, the same deduplication and sort procedure that is run on actual
pager completions is also executed for `complete -C` completions (with a `-C`
payload specified).

This makes it possible to use `complete -C` to test what completions will
actually be generated by the completions pager instead of it displaying
something completely divorced from reality, improving the productivity of fish
completions developers.

Note that completions that wouldn't be shown in the pager are also omitted from
the results, e.g. `test/buildroot/` and `test/fish_expand_test/` are omitted
from the check matches in `checks/complete_directories.fish` because even if
they were generated, the pager wouldn't have shown them. This again makes
reasoning about and debugging completions much easier and more sane.

4f46abec9d Reintroduce trivially copyable maybe_t impl
This reverts commit 1c92d4c5db and
reintroduces support for trivially copyable `maybe_t` impls but with a
GCC version check to disable the optimization for GNU GCC compiler
versions 9 and below.

GCC 8.3.0 armhf builds seem to have a problem with the trivially
copyable `maybe_t` impl that introduces odd heisenbugs that cause the
tests to fail. GDB reveals that `maybe_t` function parameters received
in the callee differ from what was passed-in by the caller.

This behavior appears to be (but has not been confirmed as) a
platform-specific compiler bug. Under the same system (32-bit Debian 10
armhf), compiling with clang 7.0.1 does not result in any bugs and
causes all the tests to pass while compiling with GCC 10.2 under 32-bit
Debian 11 armhf also doesn't run into any problems, so just expand the
existing GCC version check that gates support for trivially copyable
`maybe_t` impls to encompass both the troublesome GCC 8 version and the
untested GCC 9 version.

This reverts commit 9d303a74e3.
This reverts commit 0305c842e6.

9d303a7 broke 32-bit armhf builds for unknown reasons, specifically in
settings where a trivial copy of `maybe_t<int>` was performed. A caller
would pass a literal int in the place of a `maybe_t<int>` parameter and
the callee would see a populated `maybe_t` but with a value of `0`
rather than the actual value that was passed in. It was too painful to
debug to a resolution under qemu.
