Doesn't build yet

Remove some stuff we don't need:
    third_party libs
    Visual Studio / Xcode files
    symbian files

    pjmedia-audiodev (and update some source files accordingly)
    pjmedia-codec

    tests, documentation

define PJMEDIA_RESAMPLE_IMP PJMEDIA_RESAMPLE_NONE
    => so we don't rely on resample library

define PJMEDIA_HAS_SRTP     0
    => so we don't rely on srtp library

We do resampling and srtp ourselves anyway

sflphone-common -> daemon
sflphone-client-gnome -> gnome
sflphone-client-kde -> kde
sflphone-plugins -> plugins

It is packaged in most distributions

Reducies implicit dependencies in sfl-phone-common.

1. echocancel.cpp was missing #include <cmath>
2. astyle search was using find -exec (replaced with xargs)

- Fixed Autotools mess in test/.
- Brought all the sub-libraries into a single library with LIBADD

Conflicts:

	sflphone-common/configure.ac
	sflphone-common/src/Makefile.am
	sflphone-common/src/audio/Makefile.am
	sflphone-common/src/video/Makefile.am
	sflphone-common/src/video/decoder/Makefile.am
	sflphone-common/test/Makefile.am

ie in /usr/lib/sflphone for instance, instead of /usr/lib

was changed in order to be able to compile against pjsip with TLS enabled.
