Merge pull request #27 from nuko8/osx_test_progs

Modifications to make 'make check' test complete for Mac OS X

bench: Modify benchmarks for a wider range of platforms

 - Add the new files bench.c and bench.h to implement a timer module.
 - Implement the module with clock_gettime(), mach_absolute_time(), or
   gettimeofday(), depending on a given platform.
 - Replace the time measurement code of the benchmark programs with the
   functions of the module.

test/x11comp: Fix contention between X11 and Xvfb on Mac OS X

 - Abandon use of -displayfd.
 - Have x11comp itself look for an unused X11 display number instead.

test/x11comp: remove duplicate FOUR_LEVEL_KEYPAD from test keymap

The `test/data/keymaps/host.xkb` file contains a duplicate definition of
this type. On my computer (linux, xkbcomp 1.3.0, xserver 1.17.2), the
test passes as is, but if I remove the duplicate definition, the
roundtrip brings it back and the test fails. I can also reproduce it
without relation to the test, by loading `test/data/keymaps/host.xkb`
(without the duplicate) using

    xkbcomp -I $(pwd)/test/data/keymaps/host.xkb $DISPLAY

and downloading it again using

    xkbcomp $DISPLAY out.xkb

the duplicate is added. On Mac OS X however, the duplicate is removed
(correctly), so the test fails there.

xkbcommon itself, which was forked from xkbcomp, doesn't have this bug;
in fact, doing

    ./test/print-compiled-keymap -k keymaps/host.xkb

removes the duplicate if it is present.

This is (probably) a regression in xkbcomp or xserver compared to the
versions used in Mac OS X. Since getting a patch for any of these two is
hopeless from my experience, I did not try to investigate further.

I am not sure why, but if I also add a `PC_SUPER_LEVEL2` type, the
duplicate of `FOUR_LEVEL_KEYPAD` doesn't show up. Hopefully the test
will work on all platforms now.

state: correctly infer inactive type entries

The current test is incorrect, since 'map[None]' is entirely valid. In
most cases this doesn't cause any problems, since the default fallback
is Level1, and it's almost always 'map[None] = Level1' anyway. But in
one case in xkeyboard-config it isn't, in types/numpad(mac):

    type "KEYPAD" {
        modifiers = None;
        map[None] = Level2;
        level_name[Level2] = "Number";
    };

So before checking if no modifiers were mapped, make sure there *were*
any modifiers at all.

compose: add xkbcommon-compose - API

xkbcommon-compose is a Compose implementation for xkbcommon. It mostly
behaves like libX11's Compose, but the support is somewhat low-level and
is not transparent like in libX11. The user must add some supporting code
in order to utilize it.

The intended audience are users who use xkbcommon but not a full-blown
input method. With this they can add Compose support in a straightforward
manner, so they have a fairly complete keyboard input for Latin-like

Remove compatibility symbols

Remove the deprecated symbols that were used for ABI compatibility
during the transition period to the first stable version, 0.2.0.

The old *names* can still be used, programs which use the old names will
continue to work, as long as they were compiled against a stable
version (as they have been #defined to the new names from the start; see
xkbcommon/xkbcommon-compat.h). Namely, this will break binaries which:

1. Were compiled against a pre-stable version of libxkbcommon, and
2. Are linked against the next version of libxkbcommon, and
3. Expect to work.

This scenario is very unlikely, and will break in many other ways
anyway. Also, retaining support for these means including them in the
