this is still in progress, mostly the multisense stuff is pending.
it seems that when we merge ecore_audio in edje the libremix and
similar are gone, at least from Edje, and will be in ecore_audio
itself (or pulseaudio).
Changes:
* __UNUSED__ to EINA_UNUSED
* binaries (epp, embryo_cc, edje_cc) now consider EFL_RUN_IN_TREE and
will assume the binaries are still not installed, running from
build tree location (needs more testing, maybe doesn't work with
srcdir != builddir, still doesn't solve cross compile builds)
