For error handling code, it's nice to be able to pass NULL to these
function without worrying about segfaults ensuing. free() sets the
precedent here.
Also document this fact.

Note first:
This commits breaks the ABI somewhat. If an application is run against
this commit without recompiling against the updated header, these break:
- xkb_state_layout_*_is_active always retuns false.
- xkb_state_serialize_mods always returns 0.
So it might break layout switching in some applications. However,
xkbcommon-compat.h provides the necessary fixes, so recompiling should
work (though updating the application is even better).
Split the enum to its individual components, which enables us to refer
to them individually. We will use that later for reporting which
components of the state have changed after update.

Currently xkb_keymap_num_leds() returns a count of valid (settable)
leds. Because the indexes might be non-consecutive, and some leds
might not be settable, it is incorrect to use this function for
iterating over the leds in the keymap. But this is the main use case of
this function, so instead of the current behavior we adapt the function
to the use case by making it return the needed range of iteration.
The caller needs to handle invalid intermittent indexes, though.

xkb_keymap_num_leds() returns the number of leds that have any
possibility of being set. Even if a led is defined but can not be set in
any way, it is not counted.
In a few places currently we assume that led indexes are smaller than
this number, which is wrong both for the above reason and for the fact
that the xkb format actually allows explicitly setting the indicator
index, which means that the indexes might be non-consecutive.
We don't really have good API to iterate on leds, now, because
xkb_keymap_num_leds is pretty useless. To work around that we use
sizeof(xkb_led_mask_t) * 8.
This makes the "Group 2" led work (try switching to a layout other than
the first in test/interactive).

This is a regression introduced in ed78fbcb30.
XKB_STATE_EFFECTIVE is just a OR of the other states, so using & here is
completely wrong. So test/state shows for example:
dumping state for LCtrl down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
dumping state for LCtrl + RAlt down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for RAlt down:
group English (US) (0): effective depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for Caps Lock:
group English (US) (0): effective depressed latched locked
mod Lock (1): depressed latched locked
led Caps Lock (0): active
dumping state for Alt-Shift-+
group English (US) (0): effective depressed latched locked
mod Shift (0): depressed latched locked
mod Mod1 (3): depressed latched locked
which is bogus.

This function was always returning -1.
Adding a test, we see that test/state.c treat the is_active functions as
returning booleans, which would treat -1 as success, so we test for > 0
instead (most users would probably get this wrong as well...).
Also update the documentation for the are_active functions, and add a
ATTR_NULL_SENTINEL for gcc __attribute__((sentinel)).

For the darray we need to specify the explicit struct xkb_filter type
instead of void*, so we move the definition of struct xkb_state into
state.c thus making it opaque even from the rest of the files. It has
enough getters to get going and is otherwise good style.

Still keep things as 'ctx' internally so we don't have to worry about
typing it too often, but rename the user-visible API back as it was
kinda ugly.

"context" is really annoying to type all the time (and we're going to
type it a lot more :). "ctx" is clear, concise and common in many other
libraries. Use it!

xkbcommon-names.h right now just contains a set of hardcoded modifier
strings that are most commonly used for the usual modifiers. Provide
definitions of these so people don't have to worry about typoing a
string or mixing up Mod1 and Mod4.

Make the files in the src/* directory use their own header or a
consilidated private header. This makes the file dependencies clearer.
Also drop the pointless "xkb" file name prefix, add split a few
declarations to their own files (atom.h and text.h).

Rewrite all of the current tests in the following ways:
- Instead of the current mix of C and shell, just use single-process
pure C file per test. All of the .sh files are removed, but everything
that was tested is ported.
- Instead of handling the test logs ourselves, use Automake's
"parallel-test" mechanism. This will create a single log file for each
test with it's stdout+stderr, and a top level "test-suite.log" file
for all the failed tests.
- The "parallel-tests" directive also makes the test run in parallel,
so "make check" runs faster.
- Also use the "color-tests" directive to have the "make check" output
colorized. Who doesn't like to see PASS in green?
- All of the test data files are moved into the test/data subdirectory.
That way we can just put the directory in EXTRA_DIST and forget about
it.
- The test/Makefile.am file is consolidated into the main Makefile.am,
for a completely non-recursive build.
Right now the tests are completely independent and just use simple
assert()'s. More sophistication can be added as needed.
It should also be noted that it's still possible to use shell, python,
etc. if a test wants more flexibility than C can provide, just do as
before.

Add new API to deal with xkb_state objects, including
xkb_state_update_key, which runs the XKB action machinery internally to
calculate what exactly happens to the state when a given key is pressed
or released.
The canonical way to deal with keys is now:
struct xkb_state *state = xkb_state_new(xkb);
xkb_keysym_t *syms;
int num_syms;
xkb_state_update_key(state, key, is_down);
num_syms = xkb_key_get_syms(state, key, &syms);
More state handling API, including a way to get at or ignore preserved
modifiers, is on its way.
