package/omxplayer: new package

OMXplayer uses openMAX on the RPi to play videos with hardware
acceleration.

Compared to using a gstreamer pipe, OMXplayer uses a complete
"tunnel-mode", in which the video is piped (after demuxing) into the
hardware, all the way down to the display, whereas gstreamer composes
the video using the eglgles sink, which uses mem-to-mem copies.

So, when playing a locally-stored 1080p video, OMXplayer averages 20%
(with peaks up to ~30%, depending on the complexity of the video) CPU,
while gstreamer bursts up to 40+% when playing 720p and totally chokes
on a 1080p video; all on an non-overclocked RPi-1.

Note that we have to depend on rpi-userland. rpi-userland is a GLES/EGL
provider, so it can't be selected (as all providers of a virtual package
can't).

+Subject: [PATCH] Makefiles: clean up the cruft
+
+Most of the variables that Makefile.include tries (but fails) to set,
+are already available from Buildroot's variables:
+  - AR, AS, CC, CXX, OBJDUMP...
+  - CFLAGS, CXXFLAGS, CPPFLAGS...
+
+This leaves us with a few select variables that define include and
+library paths local to the omxplayer package, plus a few optimisations.
+
+Finally, also remove hard-coded, absolute paths pointing to the host
+system (won't work for cross-compilation, so our paranoid wrapper would
+catch those paths).
