Updated set of patches attached. This one works in older meson versions too
and adds install-world and install-quiet targets.

I also ended up getting so frustrated at the docs build speed that I started
to hack a bit on that. I attached a patch shaving a few seconds off the
buildtime.

I think we can make the docs build in parallel and incrementally, by building
the different parts of the docs in parallel, using --stringparam rootid,
e.g. building each 'part' separately.

A very very rough draft attached:

parallel with parts:
real 0m10.831s
user 0m58.295s
sys 0m1.402s

normal:
real 0m32.215s
user 0m31.876s
sys 0m0.328s

1/3 of the build time at 2x the cost is nothing to sneeze at.
