When reading back a BGRA surface the client expects the data in BGRA
order, and when we emulate the format by using a swizzled BGRA on GLES
we still have to use the original format information to read back the
data.
However, this results in mesa internally swizzling the RGBA data to BGRA
ordering on the CPU. This performance hit can be avoided for
applications that only blit or render to BGRA surfaces, because here we
can set the bgraswz tweak that does the szizzling on the GPU when
drawing or blitting to a BGRA surface and then we can read the data back
as is.
With that for vtest the bgraswz tweak becomes purley a performance
tweak. Replaying a trace of The Raven Remastered showed a 1% increase
of performance when enabling the bgraswz tweak.

Most function parameters in virglrenderer.h are opaque to the callers
(i.e., VMMs). Their definitions can be found in virglrenderer_hw.h.
In this commit, virglrenderer_hw.h simply includes virgl_hw.h.
virgl_hw.h is considered legacy however. New definitions that are not
virgl-specific will go into virglrenderer_hw.h.

Currently, even the input/output buffers are integer formats, we still
use float type for them. This is actually undefined behavior and MALI
GPU will do type conversion and cause unexpected results. To fix this,
we check the input buffer format for vertex shader and also color buffer
format for fragment shader, if they are integer types, just use integer
types in generated shaders. Since the old way works fine on other GPU,
only enable this fix for ARM MALI for now. The plan is to enable this
for other GPU also with auto detection.

Capset ids belong to virgl_hw.h. Mesa uses magic numbers right now
and can be fixed with this change.
Capset ids are also leaked in virtio_gpu.h, for use with
virgl_renderer_get_cap_set by qemu. We should replace
virgl_renderer_get_cap_set by something that enumerates all capsets
to stop the leaking, but that is another story.
