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.

Note: there's a handful more in src/gallium, although that's left as-is
to minimise merge conflicts as we have to port things from Mesa.

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

This adds a string buffer implementation + unit tests with
the following features:
- growing reallocation on append
- variadic printf-like append function
- indenting
- error state tracking (stop appending on errors)
This will be used in the GLSL shader construction to clean up
the bad string length issues we have now.
The variadic append is based on one Erik Faye-Lund wrote.
v1.1: improve indenting

- virgl maps VIRGL_FORMAT_B8G8R8X8_UNORM to GL_RGBA8
- _mesa_choose_tex_format() maps GL_RGBA8 to
MESA_FORMAT_R8G8B8A8_UNORM or MESA_FORMAT_A8B8G8R8_UNORM or
MESA_FORMAT_B8G8R8A8_UNORM.
- it ends up in (gl_texture_image *)img->TexFormat
- then in intel (_DRIImage *) image->format.
- on create image, image->dri_format = driGLFormatToImageFormat() (to
ex: MESA_FORMAT_R8G8B8A8_UNORM -> __DRI_IMAGE_FORMAT_ABGR8888)
- on query, intel_lookup_fourcc() -> __DRI_IMAGE_FOURCC_ABGR8888 == GBM_FORMAT_ABGR8888.
For some reason, driGLFormatToImageFormat() doesn't map
MESA_FORMAT_A8B8G8R8_UNORM, so I only check the two possible values I

the protocol failed to handle larger shaders, this allow
the renderer to reassemble large shaders and recombined
the chunks before passing them to the GLSL translation.
This also enhances the renderer protocol to allow
for some more info in the shader object, and removes
the separate vs/gs/fs variants in favour of a type field
in the shader.
This fixes a number of issues with how transform feedback works
it does requires ARB_transform_feedback3 to work at all, but
hopefully this extension is widespread enough, if not we can
revisit later.
It uses transform feedback objects to store the stream out
state.
