Remove Xfuncproto.h and XKB.h from xkbcommon/xkbcommon.h

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.

Remove xproto and kbproto from pkg-config file

These are no longer needed for using the library, only building it. Most
users would still want xproto though, for the keysym definitions.

Implicitly include config.h in all files

The definitions in config.h should be available in all files an
implementation detail; it can be included through the build system
instead of having each file pull it every time.

This is especially helpful with AC_USE_SYSTEM_EXTENSIONS, as _GNU_SOURCE
and friends can have an effect by merely being defined, which can lead
to some confusion if its effective for only half the files.

And we don't really support a build _without_ config.h; so, one less
thing to worry about.

Pass DFLT_XKB_CONFIG_ROOT through config.h

Instead of -D preprocessor flag. That's why it's there for.

Overhaul test suite

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 xkb_state_get_map()

This is very useful because it avoids redundent pointers in structs
and/or parameter passing in the application.

Add an interactive evdev test

The program reads key events from evdev input devices, puts them through
the library and prints some information about them. It's nice for
experimenting, quick testing and trying to break it with random stuff
(already found some!).

It is called "interactive" for lack of a better name. It's a bit
hackish, but can easily be extended, made more portable etc, in the
future.
