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.

The configure test shouldn't touch CFLAGS, because they come last on the
command line and allow to users to override settings if needed.

We still use pkg-config to get the xkb_base variable from
xkeyboard-config, but we removed all of the other PKG_ macro calls. This
still works now, because XORG_DEFAULT_OPTIONS runs it somehow. But we
shouldn't rely on it.

This runs a bunch of random keys against xkb_state_update_key() and
xkb_state_key_get_one_sym(), in a fairly unintelligent way.
It might be nice to check when modifying this code path, or changing it,
to see things haven't slowed down considerably. However, given the
numbers this benchmark gives, it is pretty clear that we are not going
to be the bottleneck for anything. So this can more-or-less be ignored.
Incidentally, this also turned out to be a poor man's fuzzer, because it
turned up the fix in the previous commit. Maybe we should consider
beefing it up with an actual 'break stuff' intention and running it as
part of 'make check'.

The current code assumes that action->type always falls in the range of
the xkb_action_type enum. But keymaps can also have Private actions,
which are allowed to set their own type number.
So with a default xkeyboard-config keymap, keycode 86 at level 4, which
triggers such an action, causes us to crash.
Fix it by always checking the bounds.

These are 'special intrest' function, like the logging functions, so
it's nice to have them in their own logical group.

This is the more appropriate for a specific key (also considering the
num_layouts() is a bit of a made-up value).

We add a return value to the xkb_state_update_key and
xkb_state_update_mask, which reports to the caller which of the state
components have changed as a result.
This restores the XKB functionality of the XkbStateNotify and
XkbIndicatorsStateNotify events. See:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Events
It is quite useful in some situations. For example, it allows an
application to avoid doing some work if nothing of relevance in the
state has changed. Say, a keyboard layout applet. Also useful for
debugging.
The deltas themselves are not provided, because I can't see a use case.
If needed, it should be possible to add some API for that.
In xkbcommon, keymaps are immutable, so all of the other *Notify events
from XKB are irrelevant.

This holds all of the state component fields in the state in one struct.
We will later want to keep the previous state components after updates,
so this will allow us to do it without duplicating the fields.

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.

And make them use context_get_buffer() instead of using a static char
array.
This was the last non-thread-safe piece we had, as far as I can tell.

First we split the LEVEL_ONE_ONLY bit off of the 'match' field, which
allows us to turn enum xkb_match_operation to a simple enum and remove
the need for MATCH_OP_MASK.
Next we rename 'act' to 'action', because we've settled on that
everywhere else.
Finally, SIMatchText is changed to not handle illegal values - it
shouldn't get any. This removes one usage of the GetBuffer hack.

The ks_tables.h file is generated by makekeys.py from
xkbcommon-keysyms.h, which in turn is generated initially by 'make
update-keysyms'. The xkbcommon-keysyms.h file is commited to git and
distributed in the tarball. Since ks_tables.h should only ever change
when xkbcommon-keysyms.h changes, it is more sensible to update them
together and treat them the same, instead of generating ks_tables.h
every time for every builder with 'make', as we do now.
This means we don't need python as a build dependency (only the one
running update-keysyms, i.e. no one, needs this), and we can be
sure exactly the same file is used by everyone. We also don't need to
run makekeys.py on every build.

This adds a flags argument to xkb_keysym_from_name() so we can perform a
case-insensitive search. This should really be supported as many keysyms
have really weird capitalization-rules.
However, as this may produce conflicts, users must be warned to only use
this for fallback paths or error-recovery. This is also the reason why the
internal XKB parsers still use the case-sensitive search.
This also adds some test-cases so the expected results are really
produced. The binary-size does _not_ change with this patch. However,
case-sensitive search may be slightly slower with this patch. But this is
barely measurable.
[ran: use bool instead of int for icase, add a recommendation to the
doc, and test a couple "thorny" cases.]

This removes the complicated and undocumented hash-table creation-helper
and replaces it with an autogenerated sorted array. The search uses simple
bsearch() now.
We also tried using gperf but it turned out to generate way to big
hashtables and when reducing the size it isn't really faster than
bsearch() anymore.
There are no users complaining about the speed of keysym lookups and we
have no benchmarks that tell that we are horribly slow. Hence, we can
safely use the simpler approach and drop all that old code.

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.
