Working DBus

We can now retrieve files from the git repository without passing them
through `asciidoc`. This allows us to retrieve images, etc..

- Attempt to implement image rendering.

Shortened the sleep() call in the thread, so that we could have less latency
when calling sendAudioFromMic(), since we check to have a full buffer before
sending.

Le tout est synchronisé avec le Manager, pour qu'on traite l'audio
et qu'on prenne le micro seulement quand c'est notre appel qui est en
cours.

IAX: Fix hangup SEGFAULTing the iax sound subsys + Add samplerate conversion to Mic output (still non-working)

Adding samplerate conversion and sound output fixed the problems of the
Jitter Buffer. It seems it updates the timestamps and causes less empty
packets crashing the system.

* Removed some debugging output.
* Cleanups

Added documentation.

Conforming to:
http://tools.ietf.org/id/draft-guy-iax-03.txt

See: http://tools.ietf.org/id/draft-guy-iax-03.txt

Removed also the now-unused libiax2.svn20060606.tar.gz that was included.

Remove also the libiax2.sh file. TODO: we need to automate the build of
libiax2 from that 'libs' directory.

Since there are multiple versions and that the official site isn't maintained,
we took the iaxclient version and merged it in here. We'll try to keep in sync
with those repos, and maybe we could host an updated version, or contact
upstream to ask them to merge the newer code.

https://iaxclient.svn.sourceforge.net/svnroot/iaxclient/trunk/
   `-> lib/libiax2

We'll try to merge often and keep up to date with them.

Use iax/iax-client.h instead of iax-client.h (from libs/libiax2)

Must be fixed, with bug #10

+ minor cosmetics
