- OMXAndroid_EnableGraphicBuffers: activate GraphicBuffers.
  Next call of OMX_GetParameter(OMX_IndexParamPortDefinition) will return a
  private eColorFormat compatible with android hal_format.

- OMXAndroid_GetGraphicBufferUsage: return hw_usage that will be used to
  allocate android hw buffers.

Some QCOM OMX_getParameter implementations override the nSize element to a bad
value. This can lead to a mediaserver crash because IOMX interface rely on
nSize to send the OMX parameter via android Binder.

"OMX_U32 nSize" is the first element of each OMX param/config struct.

Re-license almost all the playback modules to LGPLv2.1+ with
authorization from their respective contributors (230+)

This includes:
 - access, codec, packetizers, demux
 - audio filters, audio mixers, audio output
 - video filters, video chroma, video output
 - text renderers
 - XML parser
 - ARM NEON and SSE2 optimisations (mostly for chromas and filters)

Some modules are not concerned:
 - BDA and DShow access modules because Manol Manolov is AWOL
 - Real RTSP, because it is derived from Xine
 - x264 and t140 because they are encoders only
 - DLL Loader, because it is derived from MPlayer
 - DTS packetizer, because Jon Lech Johansen is AWOL
 - Shine and WMAfixed, because they are derived from Rockbox
 - Real demuxer, as it is derived from MPlayer and Wang Bo is AWOL
 - MPC demuxer, as Yavor Doganov is AWOL
 - Tivo demuxer, because it is derived from an MPlayer fork
 - Playlist demuxer, (WPL and ZPL parts missing), because suheaven is AWOL
 - iOS audio output and video display, because author refuses the license change
 - Equalizer and compressor, because Ronald Wright is AWOL
 - Mono, Headphone and Dolby, because author refuses the license change
 - hqdn3d and yadif, because they are from MPlayer/libavfilter
 - remoteosd, because it derives from RealVNC code
 - MMX optimisations, because Ollie Lho, from SiS, is AWOL
 - Rotate, because it depends on GPL motion

Nota Bene:
 - Some modules depend on GPL-only libraries, a LGPL module does not mean
   that the resulting binary module will be LGPL.
   Libraries affected would include liba52, libdvdcss, libdvdnav, libdvdread,
   faad2, libdca, libmad, libmpeg2, libpostproc, SRC, sid, zvbi and probably others.

These aren't used by the vlc omxil code, but might be used by
other omxil clients that can use the vlc iomx wrapper.

This isn't used by the vlc omxil module, but can be used by other
applications using the same iomx wrapper library.

On some devices (apparently froyo and earlier), some OMX core
(with sw-only codecs) already is loaded into the process, and
dlsym(RTLD_DEFAULT) can just as well return functions from that
one instead of the ones from the iomx wrapper that we've loaded.

This makes sure we really get the functions we want.

The separate shared library needs to be loaded into the process
before using the iomx module, preferrably by the java part
of the android application.

This allows building the iomx glue code for a number of different
ABI versions, and additionally avoids linking the main VLC
library to any private symbols that might make it unloadable.

Cool hints:
 - If your header doesn't match "Lesser" 3 times, you are not good
 - If you use LGPLv2, you are not good
 - If you use the old FSF address, you are not good

This is no longer necessary now, when the omxil module keeps
track of the number of initializations of the OMX Core.

OMX_SetConfig still lacks a good way to figure out the size of
the passed struct/variable, for now hardcoded to the size of the
only use case.

This adds a fake OMX core implementation, relying the calls
via IOMX to the media server, which contains the actual
OMX core.

Building with IOMX requires private Android headers from the
Android source tree, namely the frameworks/base and
system/core repositories. (Either froyo or gingerbread
should work for building.) This API is not public, has no
ABI guarantees and isn't supported.

Linking also requires libraries extracted from a
froyo/gingerbread device or emulator.

Since there are no ABI guarantees, linking to this API might
make the .so fail to load on some devices, so for proper use
it should be in a dynamically loaded module, separate from the
rest of the VLC core and modules.

Since this can lead to crashes on unsupported devices, it should
only be used in production on whitelisted device/firmware
combinations that are known to work.
