  build: add meson build system
  
  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.

• PACKAGING

• libxkbcommon consists of two shared libraries, libxkbcommon (the main
  library) and libxkbcommon-x11 (an addon library for XCB clients).
  
  The files for libxkbcommon-x11 are:
      libxkbcommon-x11.a libxkbcommon-x11.so* xkbcommon/xkbcommon-x11.h
      xkbcommon-x11.map xkbcommon-x11.pc
  
  libxkbcommon-x11 can be disabled with -Denable-x11=false (see
  `mesonconf build` for other options/variables).
  
  Dependencies for libxkbcommon:
  - C compiler, meson, pkg-config, libc, bash, grep, sed.
  
  - (build) bison (preferred) or byacc>=20141006.
    byacc must be configured with --enable-btyacc.
  
  - (build optional, runtime) xkeyboard-config.
    During build, for automatically detecting the value of
    -Dxkb-config-root instead of guessing (/usr/share/X11/xkb).
    During runtime, not strictly needed, but most users of the library
    would need it.
  
  - (runtime) libX11.
    Contains the dataset for Compose support (/usr/share/X11/locale).
    Please don't depend on it explicitly.
  
  - (build optional) doxygen.
    For generating the HTML documentation.
    To disable, use -Denable-docs=false.
  
  - (build optional) gperf.
    Output included in git and tarball. To regenerate, use
    `./scripts/update-keywords`.
  
  Dependencies for libxkbcommon-x11:
  - libxkbcommon.
  
  - libxcb>=1.10 with libxcb-xkb.
  
  Dependencies for libxkbcommon-x11 tests:
  - xkbcomp, Xvfb.
    If they are not available, the relevant tests are skipped.
  
  Dependencies for Wayland tests:
  - wayland-client>=1.2.0, wayland-scanner, wayland-protocols>=1.0.
    To disable, use -Denable-wayland=false.
  
  Unless libxcb is always available as part of the system, it is preferred
  that libxkbcommon and libxkbcommon-x11 be split into separate packages,
  such that the main library does not depend on libxcb. This avoids a
  transitive dependency of Wayland clients on X libraries.
