#13795: Initial commit for sflphone-android

includes: libexpat libyaml libdbus-c++ commoncpp ccrtp
          libdbus (from android-4.0.4 sources)

TODO:
- git ignores "/jni/sflphone", sflphone repo should be cloned.
- sflphone-android only needs daemon directory. Ideally it should be possible
to clone it without cloning the whole sflphone project.
into sfl-android (commit 6a0fa7a "#13961: Fix cipher handling" has been used here)
- add pjsip-android project as a git submodule
- sflphone-android needs pjsip android project. Ideally daemon git repository
should not embed pjsip. Instead pjsip should be clone from official repositories.

Considering this, structure should have three distincts git repos:

sflphone-android/.git
sflphone-android/jni/ccrtp-1.8.0-android
sflphone-android/jni/commoncpp2-1.8.1-android
sflphone-android/jni/dbus

sflphone-android/jni/libexpat
