When calling glGetnTexImage, glGetnCompressedTexImage, or
glCompressedTexSubImage*D and the data pointer is updated with the
per-slice offset but as bufSize value the full length of the
buffer was given, which can result in a crash of qemu when the buffer
size was not evaluated correctly.
Vor cubemaps instead of passing the size of the whole buffer pass the
size of the slice to make sure that glGetnTexImage doesn't write to
unallocated memory.

In the copy fallback, when a texture can not be rendered, the data that resides
in the backing iovec needs to be used. For the non-zero levels of mip-map textures
the data is located at an offset. This patch adds storing this offset and using it
when data is read from the backing iovec and updating the dst iov. We limit the
mip-map levels for which this is done to 1-17, which is enough to cover
32kx32k textures. The patch also fixes the stride when accessing mip-map levels.

Allow resources created externally (eg gbm created buffers as
dma bufs) to be used. As an example, crosvm
(https://chromium.googlesource.com/chromiumos/platform/crosvm/)
will intercept resource creation to use minigbm to allocate
buffers that its compositor is able to properly handle since it
only supports compositing with buffers allocated via minigbm.
This patch allows direct rendering to those buffers without
requiring an extra copy.

On GLES a multi-sample FBO region can only be blit to an non multi-sample
region if the source and the target rectangle are the same. The fallback
using GL and shaders doesn't work if a stencil buffer is involved, because
writing to a stencil buffer from a shader is usually not supported (i.e.
the extension ARB_shader_stencil_export is not available).
Implement a workaround for this case and also the case when the depth
buffer is involved by first blitting the complete multi-sample FBO to an
intermediate, non multi-sample FBO, and apply the region blit to the
actual target FBO afterwards.
