[PATCH rendercheck v3 1/4] Add a meson build system.

[Eric Anholt]

Meson allows the configure step to be run faster (.3 seconds compared to
autogen.sh's 3.9 seconds on my system) and a full rebuild (touch
rendercheck.h; make) to run faster (.05s instead of .07s).

Rendercheck is pretty much the best case scenario for autotools, with
limited configure-time autodetection, non-recursive make, and no
libtool, so it seems like an interesting test-case to start with for
meson conversion.

v2: Add missing check for err.h
v3: Add a linebreak after printing the version (by Peter),
    fix manpage variable substitution (anholt).
