If nr_samples is 1 we allocate textures as MULTISAMPLE, so we also need to handle
the textures in later use as a multisample texture. In addition, on GLES blits to
a multisample texture are not allowed as target, and we must use the GL blit
fallback for all texture types.
v2: Correct more checks including the one in check_resource_valid (Gurchetan)
v3: Also update the tests to use only 0 for no samples and >= 1 for samples

Transfer strides are either set internally or coming from
virgl_renderer_transfer_{write,read}_iov. As far as I can tell,
Mesa always passes sane values. We also expect sane values in
places like vrend_renderer_transfer_write_iov,
vrend_transfer_send_readpixels, and vrend_transfer_send_getteximage
already. Let's reject bad strides.
This fixes, for example, transfers to 1D array (thus box->height is
1) with non-default stride.

This commit improves bound checking by more accurately calculating
the expected transfer size. This improvement is achieved in two ways:
1. Using the image level (layer_)stride when the (layer_)stride is 0,
which matches the interpretation we use for performing the actual
read/write.
2. Calculating the transfer size by using the exact end offset in
the image, instead of using multiples of whole image rows.
The increased accuracy increases safety, and also allows us to support
some transfers with explicit strides that were previously rejected (see
added test).

There is no need to fail such transfers, in the same way we don't fail
when we are given a stride for targets without height, especially since
both stride and layer_stride have a valid (albeit possibly not very
useful) interpretation for all targets types.

Initialize the transfer box fully (and properly), instead of relying on
virgl to ignore values not relevant to the target type.

For some reason it is not possible to create a normal EGL context when
a mesa software renderer is used as a backend, and hence the unit tests
will all fail. Make it possible to force a surfaceless EGL context by
specifying the environment variable
