It only works if 'bison' or 'byacc' are provided, but sometimes byacc
is installed as plain 'yacc'. The check fails for that.
I broke this in bdd8c11, restore Daniel's retrospectively clever check.

We probably don't want to get a privileged process to compile arbitrary
keymaps. So we should be careful about the envvars which control include
paths or default RMLVOs. But then secure_getenv is more sensible for
everything we do.

- Use 'test =' instead of 'test ==' in the x11 test. The second one
might not work with e.g. dash, whoops.
- Use AS_IF instead of 'if'. It actually blends in better..

These are function to create an xkb_keymap directly from XKB requests
to the X server. This opens up the possibility for X clients to use
xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for
keyboard support.
The X11 support must be enabled with --enable-x11 for now.
The functions are in xkbcommon/xkbcommon-x11.h. It depends on a recent
libxcb with xkb enabled. The functions are in a new libxkbcommon-x11.so,
with a new pkg-config file, etc. so that the packages may be split, and
libxkbcommon.so itself remains dependency-free.
Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES
property? This does not account for custom keymaps, on-the-fly keymap
modifications, remote clients, etc., so is not a proper solution in
practice. Also, some servers don't even set it. Now, the client just
needs to recreate the keymap in response to a change in the server's
keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends).

This helps ensure we don't ship a library with undefined symbols, which
can easily happen with multiple inter-dependent DSOs.

Add a NEWS file, with some retroactive entries. Also add 'check-news' to

Older Automakes give this error without this directive:
Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'
In newer autotools this is included under AC_PROG_CC, but it's harmless
to add.

We now also work with byacc (version tested: 20130925) which some people
prefer, perhaps due to its license (public domain) or performance
(haven't compared).
When using byacc, currently the following warning comes up:
src/xkbcomp/parser.c:954:14: warning: declaration shadows a variable in the global scope [-Wshadow]
YYSTYPE yylval;
^
src/xkbcomp/parser.c:37:20: note: expanded from macro 'yylval'
#define yylval _xkbcommon_lval
^
./src/xkbcomp/parser.h:96:16: note: previous declaration is here
extern YYSTYPE _xkbcommon_lval;
This is due to a bug in byacc - it shouldn't output that extern line in
%pure-parser mode. So the warning stays.

The scanner is very similar in structure to the one in xkbcomp/rules.c.
It avoids copying and has nicer error reporting.
It uses gperf to generate a hashtable for the keywords, which gives a
nice speed boost (compared to the naive strcasecmp method at least). But
since there's hardly a reason to regenerate it every time and require
people to install gperf, the output (keywords.c) is added here as well.
Here are some stats from test/rulescomp:
Before:
compiled 1000 keymaps in 4.052939625s
==22063== total heap usage: 101,101 allocs, 101,101 frees, 11,840,834 bytes allocated
After:
compiled 1000 keymaps in 3.519665434s
==26505== total heap usage: 99,945 allocs, 99,945 frees, 7,033,608 bytes allocated

This wraps the current mmap call and adds a fallback implementation for

Some tests use linux/input.h (and epoll), but we're building on some
other kernels (e.g. debian freebsd). We could just copy the file but
it's GPL. We could also skip the tests (exit code 77) but it doesn't
really matter.

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.

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 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.

Simple HTML docs generated from the doxygen comments.
After running 'make' or 'make doc', try firefox doc/html/index.html to
see it (if you have doxygen). It's also installed with 'make install'.
You can use --enable-docs or --disable-docs, or specifically
--with-doxygen or --without-doxygen (autodetected, default yes).
The docs are currently not distributed in the tarball, because I
couldn't make it work properly in all cases :/

Since every user building the library, even from git, doesn't need these
files anymore, there's no need to check for them (this goes for makekeys
as well).
The only remaining user is the update-keysyms target, but whoever will
run it again (if ever) will probably know what he's doing (at least
enough to run git diff before git commit). And the defaults should be
fine too.
