It's been a long time since Vala invented its own "system" for getting
packages dependencies (the .deps files installed along .vapi files).
Sure it's nicer to use pkg-config directly, but not very urgent.

I've been using get_packages since the beginning, the problem for now is
that "local" packages aren't included in the list (e.g. libanjuta-1.0
for language-support-vala) and the fact that vapi files aren't always
installed system-wide. Ideally, I'd parse the VALAFLAGS for --pkg and
--vapidir but I don't know how to get that from the project manager and
I guess it wouldn't work for anything but automake with vala support
(but this shouldn't be a problem since get_packages itself only works
with automake AFAICT).

It's the consequence of not doing any error handling at all. I'll do it
as part of the above.

btw, how do I get all the sources that make up the target to which a
given file belongs? (the project manager uses GFile everywhere so I'm a
bit lost).
