macosx: fix longstanding bug where gray title bar shows window as inactive every time a movie is playing

opengl: fixed playback of 10bit content on Macs with OpenGL 1.4 drivers, notably using the GMA 950 chipset (close #5973)

We do so by forcefully disabling the 16bit shaders, which the chipset pretends to support, but actually doesn't.

These can be triggered by setting the ARCH variable respectively, which will be done by the OS X build script

additionally, update the project file for Xcode 4.3

VLCKit: disable the caca vout (which isn't supported by VLCKit's vout architecture) and libsamplerate (like we do for VLC.app)

These have been seen on HTC One V (where they were tried before
the working OMX.qcom.video.decoder.*) - they behave like they
are working, returning buffers and so on, but returns buffers filled
with 0 bytes.
