The version I attached this time has a few things that are already
working.

It starts to make sense to review this one, Srag. Although it's a patch
for Tracker, the Evolution plugin could or might some day be ported to
be generic and usable in the repo of Evolution itself (the only thing
that would have to be changed is a little bit of build-environment and
rename tracker to evolution in two or three symbols).

The EPlugin is 

src/tracker-evolution-plugin/tracker-evolution-plugin.h and
src/tracker-evolution-plugin/tracker-evolution-plugin.c

And of course

src/tracker-evolution-plugin/liborg-freedesktop-Tracker-evolution-plugin.eplug.xml

The tracker-evolution-registrar.c (which is unfinished, as I'm testing
with a Vala sample as client - attached too -) is what will run in
Tracker's processes.
