Fabiano Rosas ed8d95182b meson: Pass -j option to sphinx
Save a bit of build time by passing the number of jobs option to
sphinx.

We cannot use  the -j option from make because  meson does not support
setting build time parameters for custom targets. Use nproc instead or
the equivalent sphinx option "-j  auto", if that is available (version
>=1.7.0).

Also make sure our plugins support parallelism and report it properly
to sphinx. Particularly, implement the merge_domaindata method in
DBusDomain that is used to merge in data from other subprocesses.
