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.

There's no good reason to keep this code here; it's not like it saves us
a lot of logic, and it's unused apart from inside the glsl main.
This has the benefit of keeping struf a bit simpler; less mechanisms
needs to know about each other. Since I plan on adding more
functionality to strbuf, this will make things a lot easier.
Sadly, we don't have an easy way of doing unit-tests for the
vrend_shader internals. So for now I'm just dropping the tests here.
It's not ideal, I know, but yeah... Sorry? :P
