Mesa: fix bug with glGetIntegerv(GL_IMPLEMENTATION_COLOR_READ_FORMAT_OES)
When querying the prefered pixel format without a current color
buffer, mesa will crash. This has been fixed in upstream mesa with
two patches, which this CL backports:

framebuffer: update allowed implementation format/type
Allow additional format/type combinations based on the
color render buffer to fix failures with gles3-gtf.

mesa: handle missing read buffer in _mesa_get_color_read_format/type()
We were crashing when GL_READ_BUFFER == GL_NONE. Check for NULL
pointers and reorganize the code. The spec doesn't say which error
to generate in this situation, but NVIDIA raises GL_INVALID_OPERATION.
