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.

Unused and fairly convoluted for little reason. In practise we want a
full run when changes are made - fixing one test can easily regress
another.
Furthermore, this only works with deqp and does not throw a error when
attempted with piglit.
If needed we can reinstate this, it should handle both deqp and piglit.

There's no good reason to keep this code here; it's not like it saves us

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.

With 6a3cd2bd vrend: send list of readback-formats to guest
stricter format checks were introduced on GLES. This may lead to format
conversions in guest and host that can be avoided for additional
implementation specific readback formats. So when we build the format list
also check whether a bound texture format can also be read back from the
fbo and report the standard and additional formats also to the guest.
v2: Make things simpler and more correct (Erik) i.e.:
- default to false in the check for readback formats
- rename test function to indicate that we test color formats only
- don't pass the gl_version, instead use the epoxy functions
to get the platform info
v3: - check for DS readback support (Thanks to Erik for pointing out that this
is not available in unextended GLES)
- drop some superfluous braces (Erik)
v4: - move DS checks to separate commit (Erik)
v5: - split patch to move preparations that don't change
functionality to preceeding patches
- reduce the amount of error checking (Erik)
- only check readback for formats that can actually be used as
render targets
- remove some temporary variables (Erik)
