While the previous 1987-style[0] scheme was fun (and I reasonably
optimized it for a fair comparison), this task is more suited to a hash
table. Even a simple implementation beats the old one.

Specify where to find the headers for libxkbcommon_dep,
libxkbcommon_x11_dep, and libxkbregistry_dep, which allows other
projects to correctly locate the headers when libxkbcommon is being
built as a Meson subproject.
The dep_libxkbregistry variable is renamed to libxkbregistry_dep,
to follow the usual convention for variables which hold declared
dependencies to be used from subproject builds.
Arrange for passing .def files with the lists of symbols to export from
DLLs when building on Windows with MSVC. Without this no symbols were
being exported at all.
The .def files are generated from the .map files at build time using
scripts/map-to-def, which avoids needing to maintain two different sets
of files.
We have a lot of keyboard layouts and the current output format is virtually
useless at searching for a specific one to debug any issues with either the
layout list or the output from libxkbregistry.
Let's use YAML instead because that can easily be post-processed to extract the
specific layouts wanted, e.g. to get the list of all layouts:
xkbcli-list | yq -r ".layouts[].layout"
to get the list of all variants of the "us" layout:
xkbcli-list | yq -r '.layouts[] | select(.layout == "us") | .variant
and the number of option groups:
xkbcli-list | yq -r '.option_groups[] | length'
Note that the top-level nodes have been de-capitalized, so where it was "Models"
before it is now "models" and the "Options" node is now "option_groups".

This is hit when passing an empty string and XKB_KEYSYM_CASE_INSENSITIVE
to xkb_keysym_from_name currently if `(lo + hi) / 2` is 0 and `cmp < 0`,
causing mid to underflow and the the array access into name_to_keysym on
the next iteration of the loop to be out of bounds .
We *would* use ssize_t here as it is the appropriate type, but windows
unfortunately does not define it.
Add a skipError test function that can analyse rc, stdout, stderr to skip a test
even when we expect an error. We use that to skip if we couldn't find a keyboard
in the interactive-evdev test.

tqdm prints to stderr by default but we're using that for failed keymap
compiles (which are the ones that really matter). Plus, whether we're using tqdm
is dependent on isatty(sys.stdout) anyway.

With --keymap-output-dir, the given directory will contain a list of files named
after the layout + variant ('us', 'us(euro)', ...) that contain the keymaps for
each variant + option combination compiled.
This is still a lot, but better to sift through hundreds of keymaps than tens of
thousands.

The previous output is largely unusable. The result in the CI test runs is a 6GB
file with every compiled keymap in it and while we can grep for ERROR, it's not
particularly useful.
Let's change this and print out YAML instead - that can be machine-processed.
This patch adds a new parent class that prints itself in YAML format,
the tool invocations are child classes of that class. The result looks like this:
Example output:
- rmlvo: ["evdev", "pc105", "us", "haw", "grp:rwin_switch"]
cmd: "xkbcli-compile-keymap --verbose --rules evdev --model pc105 --layout us --variant haw --options grp:rwin_switch"
status: 0
- rmlvo: ["evdev", "pc105", "us", "foo", ""]
cmd: "xkbcli-compile-keymap --verbose --rules evdev --model pc105 --layout us --variant foo"
status: 1
error: "failed to compile keymap"
Special status codes are: 99 for "unrecognized keysym" and 90 for "Cannot open
display" in the setxkbmap case.

The numpad:mac option doesn't specify a name for the first level:
// On Mac keypads, level 1 and 2 are swapped.
partial xkb_types "mac" {
type "KEYPAD" {
modifiers = None;
map[None] = Level2;
level_name[Level2] = "Number";
};
include "extra(keypad)"
};
This means the atom for level name is XCB_ATOM_NONE. We tried to get its
name, which fails. This regressed in 40c00b4721.
Instead, translate it to XKB_ATOM_NONE, same as the previous behavior.

In 7d84809fdc I added a fast path for the
case-sensitive case, but it is still slowing down Compose parsing.
Instead of the binary search, use a perfect hash function, computed with
a simple python module I found (vendored).
It is faster -- perf diff is:

Also reduces the binary size:

After:

Note however that it's still larger than before 7d84809fdccbb5898d08388:

Previously we used a simple trie with a linked list for each chain.
Unfortunately most compose files have very long chains which means the
constructions performs an almost quadratic number of comparisons.
Switch to using a ternary search tree instead. This is very similar to a
trie, only the linked list is essentially replaced with a binary tree.
On the en_US/Compose file, the perf diff is the following (the modified
function is `parse`):
Event 'cycles:u'

Thanks to some careful packing, the memory usage is pretty much the
same.

Fits in uint16_t, which enables some future optimizations. But also a
