adbd9d3c05 glupload: Keep input frame mapped as long as needed
When performing a raw upload, we need to keep the raw data mapped as
long as needed.

c3a47c910d 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.

7d8d1f8206 glmemory: implement on top of glbasebuffer
Provides convenient access to PBO usage.

Currently texture updates are coupled tightly to data transfers.

4db0ef5789 glmemory: Use fallback for partial copy
When the memory is partial copy, the texture size and videoinfo no
longer make sense. As we cannot guess what the application wants, we
safely copy into a sysmem memory.

b8f168cd65 glmemory: Add GstAllocationParams and alignment support
This implements support for GstAllocationParams and memory alignments.
The parameters where simply ignored which could lead to crash on
certain platform when used with libav and no luck.

a4040f2ee9 glememory: only store and act on the map flags on first/last map/unmap
Anytime else, we have no idea how to match up map and unmaps.
We also don't know exactly how the calling code is using us.
Also fixes the case where we're trying to transfer while someone else
is accessing our data pointer or texture resulting in mismatched video
frames.

5f547c5600 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.

9a55a3f98c glmemory: use pbo's for download
In order to use pbo's efficiently, the transfer operation has to
be separated from the use of the downloaded data which requires some
rearchitecturing around glcolorconvert/gldownload and elements

da3ae06cd1 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.

598a79a5e2 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.

15d0c04933 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.
