Left shift of a negative integer. For some reason the protocol
representation here got really botched (in the spec it is just a nice
and simple INT16).

Though text formats aren't exactly fuzzer's strong suit, fuzzers can
catch many surface-level bugs.
The fuzz/ directory contains target programs, testcases and dictionaries
to drive the afl fuzzer.
This commit adds a fuzzer for the XKB keymap text format and the Compose
text format. On my slow machine, using a single core, a full cycle of
the XKB fuzzer takes 5 hours. For Compose, it takes a few minutes.
Fuzzing for the other file formats (rules files mostly) will be added
later.
To do some fuzzing, run `./fuzz/fuzz.sh`.

Old meson expects an array with one dependency per element. Providing a
string containing multiple deps results in only the first dep getting
its whitespace properly applied. As a result, the output was:
Requires.private: xcb >= 1.10 xcb-xkb>=1.10
And downstream projects failed to find a package named 'xcb-xkb>=1.10'.
Specifying an array of versioned deps results in correct output:
Requires.private: xcb >= 1.10, xcb-xkb >= 1.10
Fixes#64.

The meson-generated pkgconfig file was missing Requires and
Requires.private.
[ran: adjust for older Meson versions.]

Trim the API a bit.
Also, just always use gettimeofday(), which is portable. Hopefully the
system clock doesn't change while a benchmark is running.

The x11 tests/demos did not depend on xcb and xcb-xkb directly, only
indirectly through link_with: libxkbcommon_x11_internal. So linking
worked, but the xcb and xcb-xkb cflags were *not* included when
compiling them. So when using xcb installed in a non-standard location,
what would happen is:
- Library will link with custom xcb and compile with custom xcb headers.
- Test will link with custom xcb and compile with system xcb headers (if
exist, otherwise fail).

We will never remove the deprecated functions and there is no real
reason to annoy users into stop using them.
If there *will* be a reason, *then* we will add the attribute.

Meson is easier to maintain, much faster, encourages better practices,
and is not built on a pile of shell scripts.
The autotools build system is kept intact for now, in order to ease the
migration. The intention is to remove it sooner rather than later, if
all goes well.
Run `meson build && mesonconf build` to see the configuration options
for the new system. Conversion should be straightforward. Environment
variables like CFLAGS work the same.
If meson is used, xorg-util-macros is not required.
In terms of functionality the two systems have about the same
capabilities. Here are some differences I noticed:
- Meson uses `-g` by default, autotools uses `-g -O2`.
- In autotools the default behavior is to install both static and shared
versions of the libraries. In meson the user must choose exactly one
(using -Ddefault_library=static/shared).
It is possible to workaround if needed (install twice...), but
hopefully meson will add the option in the future.
- Autotools has builtin ctags/cscope targets, meson doesn't.
Easy to run the tools directly.
- Meson has builtin benchmarks target. Handy.
- Meson has builtin support for sanitizers/clang-analyzer/lto/pgo/
coverage etc. Also handy.
