If we can't find the component of the include file we're looking for,
make sure we don't return success when we meant failure, segfault, or
spectacularly leak everything.
Tested with incorrect component includes for keycodes, compat, symbols,
and types.

Instead of allowing only one keysym per level per group, do as the
external API indicates and allow multiples. The existing syntax is:
key <AD01> { [ q, Q ] };
where the new syntax is:
key <AD01> { [ q, Q, { H, E, L, L, O },
{ Y, E, S, space, T, H, I, S, space, I, S, space, D, O, G } };
to make the key in the extreme top left of the keyboard do pretty
surprising things in levels 3 and 4.

Unify all the different Makefile.am into a single short top level one
(the test/Makefile.am file is left intact though).
This makes the build system simpler to look and should encourage
unifying more currently-disparate code.

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.

Previously, we would clear out the real modmask when updating the
modmask for action maps, if not using the key's modmask. The correct
behaviour here is instead to use the key's modmask if using the modmap,
else use the real mods provided with the action originally.

On many layouts, the following error appears:
Internal error: Could not resolve keysym 10005b0
(Which is like the trademark of libxkbcommon now, and makes
unicode-heavy symbol files pretty useless).
This occurs when a keysym string (in this case, 10005b0) is passed to
xkb_string_to_keysym, but cannot be resolved.
This in turn happens because the parser passes on hexadecimal keysym
strings without the leading "0x", thus leaving the resolving function
without a way to disambiguate it as a number.
Therefore, make sure to pass on the "0x". The file symbols.c in xkbcomp
project does the same; it probably got lost in translation.
