45ac36ca26 glmemory: Handle upload/download flags from map
Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

132a233f7b gl/memory: implement GL_EXT_texture_rg support
Which is used by default over the Luminance formats due to it
being color renderable with fbos (and deprecation/removal with
GL 3.x).

33091ff6a5 gl/mem: implement texture copying between formats with strides properly
Previously, we used the width to determine the amount of data to be
copied using pbos.  This, makes it allocate enough data for the
the strides as well.

30c6efc432 gl/mem: allocate the memory per plane
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).

Should not lose any features/video formats.

d17a4381b1 [732/906] build: fix repeated typedefs
Write forward declarations in another way to avoid
repeated typedefs "error: redefinition of typedef".
Raised when using i686-apple-darwin11-llvm-gcc-4.2
It seems that C apple compiler does not support
C11 feature.
