meson: basic build system support

Why?

Because it's fast.

Like really, really fast.

Some data (from a snb laptop, so rather lower-powered):

- Incremental build after $ touch lib/igt_core.c with meson: 0.6s
  It notices that the symbol list of the libigt.so hasn't changed and
  doesn't bother re-linking the almost 300 binaries we have. make -j 6
  for the same scenario takes 44s.

- Incremental build with nothing changed: make: 0.7s, meson: 0.2s This
  means stuff like --disable-git-hash is entirely pointless with
  meson, it's faster than a make ever can be (with 0.6s).

- Reconfigure stage: ninja reconfigure 0.8s vs. ./configure 8.6s)

- Running tests, after a full build: ninja test 6s vs. make check 24s

- Full build (i.e. including ./autogen.sh respectively meson build),
  including tests, from a pristine git checkout. automake 2m49s vs.
  meson 44s.
