Can happen in cases like:
- There was an error between the error check and the call.
- The internal poll() fails.

The enum seems large, and we don't handle all of the values in it.
Previously if we got an unrecognized SHM format we would use an
uninitialized `stride`.

Mutter only implements v6 now, and Weston also implements that. Port
interactive-wayland to this so people can keep on using it.

We currently use strcasecmp, which is locale-dependent. In particular,
one well-known surprise even if restricted just ASCII input is found in
the tr_TR (Turkish) locale, see e.g.
https://msdn.microsoft.com/en-us/library/ms973919.aspx#stringsinnet20_topic5
We have known to avoid locale-dependent functions before, but in this
case, we forgot.
Fix it by implementing our own simple ASCII-only strcasecmp/strncasecmp.
Might have been possible to use strcasecmp_l() with the C locale, but
went the easy route.
Side advantage is that even this non-optimized version is faster than
the optimized libc one (__strcasecmp_l_sse42) since it doesn't need to
do the locale stuff. xkb_keysym_from_name(), which uses strcasecmp
heavily, becomes faster, and so for example Compose file parsing, which
uses xkb_keysym_from_name() heavily, becomes ~20% faster.

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).
So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.
All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.
Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

Takes care of GCC's annoyingly persistent warn_unused_result warnings.
But it's better to avoid system() I suppose.

More meticulously free everything we create, including hooking up the
buffer-release callback so we actually free those when required. Make
sure seats are actually in the display's seat list.
The xkbcommon object-unref functions don't actually require
NULL-checking, so we can elide those.

interactive-wayland is very similar to x11/xev, and dumps out as much
state as possible.
It provides no titlebar and a completely random cursor, but such is
life.

xkb_keymap_key_by_name() allows finding a keycode from a given keyname and
is useful for generating keyboard events to use in regression tests
during CI
xkb_keymap_key_get_name() is the inverse of xkb_keymap_key_by_name()

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.

xkbcomp doesn't need the search-path argument, since we pass an absolute
path. Keep the plain -I which clears the search path just to be sure.

Some results from the benchmark (compilation of en_US.UTF-8/Compose):
$ grep 'model name' /proc/cpuinfo
model name : Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz
model name : Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz
$ uname -a
Linux ran 3.16.1-1-ARCH #1 SMP PREEMPT Thu Aug 14 07:40:19 CEST 2014 x86_64 GNU/Linux
$ ./test/compose bench
compiled 1000 compose tables in 7.776488331s
So according to the above benchmark and valgrind --tool=massif, an
xkb_compose_table adds an overhead of about ~8ms time and ~130KB
resident memory.
For contrast, a plain US keymap adds an overhead of ~3ms time and 90KB
resident memory.

If the keymap doesn't have any key-aliases (which is certainly
possible), the calloc(num_key_aliases, ...) is allowed to return NULL
according to the C standard, but this is not an error.

There is really no reason to deny these tests from different platforms
only for a few #defines.
The only linux-only test (or test program, it is not run by make check)

libxkbcommon 0.4.3 introduces a new test, x11comp, which does not build
on non-Linux OSes because of the unconditional <linux/input.h> include.
This seems not needed even on Linux, so attached there is a simple patch
to remove it.

If Xvfb is not present, posix_spawn still forks, but the child fails.
In that case, since we left the write fd of the pipe open in the parent,
we just kept waiting on the read() without noticing that the other side
is dead.

It is like test/stringcomp, only instead of using
xkb_keymap_new_from_string(), it uses xkbcomp to upload the keymap to a
dummy Xvfb X server and then xkb_x11_keymap_new_from_device().
If any of these components are not present or fails, the test is shown
as skipped.
The test is messy, fragile, limited and depends on external tools, but I
will improve on that later -- it's better to have a test.
