applemedia: rework GL texture sharing
...
Use YUV instead of RGB textures, then convert using the new apple specific
shader in GstGLColorConvert. Also use GLMemory directly instead of using the
GL upload meta, avoiding an extra texture copy we used to have before.

as the DPB size is larger than the max bframe forward prediction length, but I

applemedia: don't use the dynamic API for public frameworks

Public frameworks don't need to build the API dynamically, we instead
use the framework directly.
The exception is for VideoToolbox which went public in the 10.8 SDK,
but it's still private in older version of the SDK and iOS. This allow
building the plugin against SDK's where it's not a public framework.

These callbacks may fire from any thread, hence we should only enqueue
buffers and let the streaming thread take care of the rest as soon as
the blocking encode or decode operation has finished.

The codec that called us might be holding locks to shared resources, so
we should never push downstream from within its buffer callback.
Note that a GstBufferList is not used here because we need to preserve
the buffer metadata held by our GstBuffer subclasses.
