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.

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.

centre outside the clip volume will be partially drawn when they overlap with
the clip volume because of being "wide" (i.e. when moving towards the clip
volume boundary a wide point would "naturally" move out). The OpenGL standard
defines that points should be clipped the moment the centre is outside the
clip volume (i.e. points will "pop" in and out of the view when moving across
the border). Hence, for a host implementation following the standard to the
letter these tests should actually fail.
