Add build-api wrapper for Meson
Add build-api wrapper for Meson

Autobuilders and distributions are usually conforming to a "build API"
based on autotools:

  [ test -x ./configure ] && ./configure --prefix=...
  make
  make DESTDIR=... install

See:

Now that we dropped autotools, we can ship with a small "configure"
script that wraps the invocation of Meson with the appropriate
arguments, and generates a dummy Makefile that calls Ninja with the
appropriate targets and destination directory.
