everything more readible.
* Once I understood better how everthing is supposed
to work, I've fixed some bugs.
* The most important problem was that AddDirectory()
placed the wrong entry (resolved symlinks) into the
entry list it keeps for each directory. This resulted
in the mechanisms not working at all when an add-on
was a symlink.
* There was a hidden TODO, which would mean that moving
an add-on from one watched directory into another,
like from home/config/add-ons/... into common/add-ons/...
would drop the client application (media_server,
input_server, ...) into the debugger.
* The fFormerEntries list did not seem to serve any
purpose. Basically it would not disable add-ons
removed from a watched directory unless it changed
it's name at the same time. I've removed it completely,
since it didn't seem to be an optimization
(entry cache) either.
* Each actual add-on file is now node-monitored for
stat changes. So if you have a link in the add-on
folder, and the linked to add-on changes, it triggers
a reload of the add-on now. This will make it much
more pleasant to develop add-ons and have them affective
immediately.
I tested with a fresh image, but there are no immediate
regressions I am aware of. I could imagine that messing
with certain add-ons can have a bad effect now, like
removing the keyboard input_server add-on may trigger the
keyboard to stop working immediately without an input_server
restart, but Tracker should warn before it happens.
