Reason: the second parameter in glBufferSubData() is the offset,
but in vrend_read_from_iovec_cb() function in iov.c, the "count"
is passed to it causing to possibly write beyond the buffer boundary
(or at wrong offset).

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.
v2: Handle missing extension better.
v3: Update commit message with more details on usage.

virgl_renderer_resource_get_info() doesn't return the underlying image
stride. eglExportDMABUFImageMESA() does. This fixes imports failing
due to a stride mismatch under certain resolutions. (note that qemu
uses its own export methods, perhaps because Gerd noticed the problem
with virgl egl export functions)

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.
Fixes:

Two functions are extracted from vrend_renderer_resource_create to
make it possible to allocate a texture resource without adding too much
code duplication:
vrend_renderer_resource_copy_args:
copies all required arguments from the args struct into the
already allocated resource
vrend_renderer_resource_allocate_texture:
Allocate a texture using the parameters in the given resource struct
v2: * instead of extracting the complete allocation also including buffers,
only extract the parts that copy the parameters and allocate the texture
* use latest upstream that also includes texture storage objects
