2210ba5d46 glmemory: separate pbo transfer from texture transfers
When supported, the potentially longer pbo upload/download can be
initiated before the texture upload/download, potentially increasing
throughput.

fce0e0ba3c gl: add and use gst_gl_internal_format_rgba
Previously when compiling GstGL with both GL and GLES2,
GL_RGBA8 was picked from GL/gl.h. But a clash may happen at
runtime when one is selecting GLES2.

gst_gl_internal_format_rgba allows to check at runtime
if it should use GL_RGBA or GL_RGBA8.

cc587ce1f1 glmemory: properly detect (hopefully) the correct ext_rg/arb_rg variant
GL_EXT_texture_rg is only valid for GLES2. GLES3 uses similar wording to
the GL_ARB_texture_rg which requires a sized internal format that the
GL_EXT_texture_rg does not require.

966cad27d7 gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

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.

texture to hold the data causes the glmemory to have half width
