This mirrors the autotools option for all server-side dynamic libraries.

 - Rename "pulsedspdir" to the same "padsplibdir" that Autotools uses.

 - Add a new option "pulsedsp-location" that is only used for padsp.in,
   just like Autotools' --with-pulsedsp-location.

 - Use 'set' instead of 'set_quoted' to avoid PULSEDSP_LOCATION getting
   quoted twice.

This is to avoid using the construct 'join_paths(prefix, get_option(...))'
everywhere in the meson files. It's better to settle the paths question
once and for all at the beginning.

Regarding the module:

This is unlike the autotools where liboss-util is built as a library,
here we build everything in the oss module, as apparently there's no
other consumer for liboss-util.

Regarding padsp:

Setting the install mode for padsp requires meson 0.47, so instead we
set padsp.in as executable in the git repository (which is what glib
does for gdbus-codegen btw).

This is a working implementation of a build with meson. The server,
utils, and most modules build with this, and it is possible to run from
a build tree and play/capture audio on ALSA devices.

There are a number of FIXMEs, of course, and a number of features that
need to be enabled (modules, dependencies, installation, etc.), but this
should provide everything we need to get there relatively quickly.

To use this, install meson (distro package, or mesonbuild.com) and run:

  $ cd <pulseaudio src dir>
  $ meson <builddir>
  $ ninja -C <builddir>
