vallium: initial import of the vulkan frontend

This is the initial import of the vallium frontend for gallium.
This is only good enough to run the triangle and the gears demo
(wrongly) from Sascha demos.

Improvements are mostly on the llvmpipe side after this.

It contains an implementation of the Vulkan API which is mapped
onto the gallium API, and is suitable only for SOFTWARE drivers.

Command buffers are recordred into malloced memory, then later
they are played back against the gallium API. The command buffers
are mostly just Vulkan API marshalling but in some places the information is
processed before being put into the command buffer (renderpass stuff).

Execution happens on a separate "graphics" thread, againt the gallium API.

There is only a single queue which wraps a single gallium context.

Resources are allocated via the new resource/memory APIs.
Shaders are created via the context and bound/unbound in the
second thread.

(No HW for reasons - memory management, sw paths for lots of paths,
pointless CPU side queue)

gallium: add an interface for memory allocations.

In order to support vulkan over gallium for the sw renderers,
there needs to be a vulkan-like memory allocation API.

It doesn't need to be overly complicated for the needs of the sw
renderers.

The vallium layer will allocate resources and memory separately
and bind them via this API.

gallium: Use unpack_rgba() instead of fetch_rgba in translate_generic

This is the only user of fetch_rgba outside of llvmpipe, and it's in the
fallback path of this fallback path.  Looking at an example of these two
functions, b8g8r8a8's unpack_rgba is 2.7x as long as fetch_rgba.  It feels
reasonable to sacrifice some perf in this already slow (VBO readback, and
a function pointer call per attribute per vertex) path to reduce our
binary size.  And, if I ever finish getting unpack codegen to switch to
rows instead of rects, that factor will go back down.
