efl: merge emotion.
this one was quite a huge work, but hopefully it's correct. NOTES: * removed vlc generic module, it should go into a separate package. * gstreamer is enabled by default (see --disable-gstreamer) * xine is disabled by default (see --enable-gstreamer) * generic is always built statically if supported * gstreamer and xine can't be configured as static (just lacks command line options, build system supports it) * v4l2 is enabled by default on linux if eeze is built (see --disable-v4l2) * emotion_test moved to src/tests/emotion and depends on EFL_ENABLE_TESTS (--with-tests), but is still installed if enabled. TODO (need your help!): * fix warnings with gstreamer and xine engine * call engine shutdown functions if building as static * remove direct usage of PACKAGE_*_DIR and use eina_prefix * add eina_prefix checkme file as evas and others * add support for $EFL_RUN_IN_TREE * create separate package for emotion_generic_modules * check docs hierarchy (doxygen is segv'in here) SVN revision: 82501
