This avoids a couple of special cases in the code, and is more
consistent. Since anyone who includes xkbcommon.h also gets
xkbcommon-keysyms.h, and anyone who include xkbcommon-keysyms.h would
want NoSymbol anyway, there's no down side.

This code uses a table and code derived from
http://www.cl.cam.ac.uk/~mgk25/ucs/keysym2ucs.c
The added API calls are:
xkb_keysym_to_utf32
xkb_keysym_to_utf8
[daniels: Changed API to be more in line with keysym_get_name, added
test, changed formatting to 4-space.]
i.e. xkb_map_new_from_file. The reason is that flex only works with
FILE's, so we must use fdopen on the file descriptor; but to avoid a
memory leak, we must also fclose() it, which, in turn, closes the file
descriptor itself.
Either way is not acceptable, so we can either:
* dup() the fd and use fdopen on that, or
* have the user call fdopen on his own, and accept a FILE* instead of an
fd.
The second one seems better, and is standard C, so why not. We must add
stdio.h to xkbcommon.h though, which is regrettable, but not a big deal.

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.

It was a pretty pointless check. Also sanitise the _x11 variant to
actually do what it says on the box.

(This breaks the API.)
"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!

[daniels: Fix for xkb -> keymap change.]
Change them to refer to the string representation of the keysym's name
as a name rather than a string, since we want to add API to get the
Unicode printable representation as well.

Two new calls allow users to test the exact modifier state, including
verifying that no other modifiers but the ones you wanted are down.
Signed-off-by: Daniel Stone <daniel@fooishbar.org>
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.

This reverts commit d007cd0a1f.
This is in fact more restrictive, because it breaks the (common) case
where the strings are const themselved, e.g. "evdev", "us", etc. As is
you must either duplicate the strings or suppress the warnings.
If the user needs to retain the non-const strings, he should instead
just keep them in some other struct and use xkb_rules_names just as
a temporary parameter for xkb_map_new_from_names. Mildly annoying but
acceptable.
This is very useful because it avoids redundent pointers in structs
and/or parameter passing in the application.

The kbproto header is already not needed here anymore.
Move the _X_EXPORT's to the corresponding function definitions, and use
straight extern "C" clauses instead of _XFUNCPROTOBEGIN/END.
It also makes more sense to have the EXPORT's in the source files, as it
provides some documentation to the reader, whereas in the header it's
obvious.

xkb_state_ref was missing.
Also modify the _ref functions to return the object instead of being
void. This is a useful idiom:
struct my_object my_object_new(struct xkb_state *state)
{
[...]
my_object->state = xkb_state_ref(state);
[...]
}
Essentially "taking" a reference, such that you don't forget to
increment it and it's one line less (see example in our own code).
A case could also be made for _unref to return the object or NULL, but
this is quite uncommon.

(They were not reported, see next commit).
The reset function declaration didn't match its name in the definition;
the _defaults variant matches better with the rest.

Since we never return an xkb_rules_names and it's all user-provided
strings, seems a bit harsh to have it const.

Since we have our own xkb_keysym_t type, it makes sense to have our own
NoSymbol value instead of the one from X11/X.h.

And also convert state.c to use the state API for mods and groups,

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.
