Fix: missing sanity check in ScopedCollection

funny enough this possible memory corruption
didn't happen in the unit test, because my
compiler optimised the additional int field
of class SubDummy, making it the same size
of the baseclass. Now matters should be safe.

initial draft for the job representation

this draft is based on
- Cehteh's draft for the scheduler
- my plannings about segmentation and JobTicket
it defines "Job" as a closure which can be invoked
from plain-C, using the information in the
job descriptor datastructure

from the relevant mailing list discussions.

ALSA audio output experiment
...
I think it's smart to rather use ALSA directly instead of PortAudio.
ALSA is push AFAIK, and talking about it here at the hackspace, seems
like the better choice. It's a bit lower level, but anyway everything
speaks ALSA anyway. It's not like there's any reason to use PortAudio
at all. It's just an extra abstraction.
Coding for ALSA it'll also work with Pulseaudio and esd. Do people
really use other sound systems than Pulseaudio, esd or plain ALSA?
I can't think of it.
I really the idea about building a small tool first. I'll do that.
Also thought about making a small blikning cursor/text output, and
syncing a BEEP-sound to that, so that I can test around with throwing
in lots and lots of latency between "me" and the video, and try to
sync it anyway.
I should be able to read back from the sound card (or pulse audio
underneath, it will just work with alsa as the abstraction) how long
it takes for the bytes I'm pushing to reach the speakers, and do some
buffer tuning on that.

The goal is to make the build scrips more clear

The final goal of this makeover is to reduce
the main SConstruct as much as possible
