8729623cec Make ESCAPE_ALL the default and call its inverse ESCAPE_NO_PRINTABLES
ESCAPE_ALL is not really a helpful name. Also it's the most common flag.
Let's make it the default so we can remove this unhelpful name.

While at it, let's add a default value for the flags argument, which helps
most callers.

The absence of ESCAPE_ALL makes it only escape nonprintable characters
(with some exceptions). We use this for displaying strings in the completion
pager as well as for the human-readable output of "set", "set -S", "bind"
and "functions".

No functional change.

bd5610349d Fix pager backwards movement on half-filled last column
If the completion pager renders as

	foo1 bar1 baz1 qux1
	foo2 bar2 baz2
	foo3 bar3 baz3

and we go backwards from "foo1" (using left arrow), we'll end up at "baz3",
not "qux1". Pretty smart!

If however we go backwards once more, nothing happens.

The root cause is that there are two different kinds of selection indices:
the one before rendering (9/qux1) and the one after we cleverly subtract
the half-filled last column (8/baz3). The backwards movement ends up
decrementing the first, so it moves from 9 to 8 and nothing changes in
the rendering.

Fix this by using the selection index that we actually rendered.

There is another caller that relies on the old behavior of using the unrendered
selection index. Make it use a dedicated overload that does not depend on
the rendering.

64b34c8cda Allow complete to have multiple conditions
This makes it so `complete -c foo -n test1 -n test2` registers *both*
conditions, and when it comes time to check the candidate, tries both,
in that order. If any fails it stops, if all succeed the completion is offered.

The reason for this is that it helps with caching - we have a
condition cache, but conditions like

```fish
test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length

test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] sub
```

defeats it pretty easily, because the cache only looks at the entire
script as a string - it can't tell that the first `test` is the same
in both.

So this means we separate it into

```fish
complete -f -c string -n "test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
+complete -f -c string -n "test (count (commandline -opc)) -ge 2" -n "contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
```

which allows the `test` to be cached.

In tests, this improves performance for the string completions by 30%
by reducing all the redundant `test` calls.

The `git` completions can also greatly benefit from this.

"feature_flags_t::set". We simply shouldn't do that.

c48b02e418 fixup! Fix commandline state for custom completions with variable overrides
The previous commit added transient commandlines when completing
commands with variable overrides. Transient commandlines require a
parser, but perform_one_completion_cd_test() asked for completions
without giving a parser, which is only okay when asking for
autosuggestions (like perform_one_autosuggestion_cd_test() does).
Let's pass a parser to fix the test.

57a9fe492e Allow using poll() to check for readability
Cygwin tests are failing because cygwin has a low limit of only 64 fds in
select(). Extend select_wrapper_t to also support using poll(), according to
a FISH_USE_POLL new define. All systems now use poll() except for Mac.

Rename select_wrapper_t to fd_readable_set_t since now it may not wrap
select().

aaac759d9a Make test a custom target again and add top-level test targets
Even though we are using CMake's ctest for testing, we still define our
own `make test` target rather than use its default for many reasons:

 * CMake doesn't run tests in-proc or even add each tests as an
   individual node in the ninja dependency tree, instead it just bundles
   all tests into a target called `test` that always just shells out to
   `ctest`, so there are no build-related benefits to not doing that
   ourselves.
 * CMake devs insist that it is appropriate for `make test` to never
   depend on `make all`, i.e. running `make test` does not require any
   of the binaries to be built before testing.
 * The only way to have a test depend on a binary is to add a fake test
   with a name like "build_fish" that executes CMake recursively to
   build the `fish` target.
 * It is not possible to set top-level CTest options/settings such as
   CTEST_PARALLEL_LEVEL from within the CMake configuration file.
 * Circling back to the point about individual tests not being actual
   Makefile targets, CMake does not offer any way to execute a named
   test via the `make`/`ninja`/whatever interface; the only way to
   manually invoke test `foo` is to to manually run `ctest` and specify
   a regex matching `foo` as an argument, e.g. `ctest -R ^foo$`... which
   is really crazy.

With this patch, it is now possible to execute any single test by name,
by invoking the build directly, e.g. to run the `universal.fish` check:
`cmake --build build --target universal.fish` or
`ninja -C build universal.fish`. Unfortunately, this is not integrated
into the Makefile wrapper, so `make universal.fish` won't work (although
this can potentially be hacked around).

26092456d4 Add CMake enumeration of low-level fish_tests.cpp tests
Instead of compiling `fish_tests.cpp` dynamically with weakly-linked
symbols and asking it to print the list of all available tests, we
use a magic string `#define`'d as a no-op to allow CMake to regex search
for matching test groups. This speeds up configuration somewhat (by not
compiling anything), but more importantly, it's much less brittle and
doesn't involve and linker dark magic.

There's of course still no getting around the fact that it's really ugly.
