If host support dual_src_blend extension, it's possible we need

We can't explicitly set it in GLSL in such cases.

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.

A blob resource is a container for:
- VIRGL_RENDERER_BLOB_MEM_GUEST: a guest memory allocation
(referred to as a "guest-only blob resource")
- VIRGL_RENDERER_BLOB_MEM_HOST3D: a host3d memory allocation
(referred to as a "host-only blob resource")
- VIRGL_RENDERER_BLOB_MEM_HOST3D_GUEST: a guest + host3d memory allocation
(referred to as a "default blob resource").
Blob resources can be used to implement new features and fix shortcomings
with the current resource create path. The subsequent patches show how
blob resources may be leveraged to implement GL_ARB_buffer_storage
and GL4.5.
