i965: Move brw_context format arrays to intel_screen

This allows us to query the driver's supported formats in i965's DRI code,
where often there is available a DRIscreen but no GL context.

To reduce diff noise, this patch does not completely remove
brw_context's format arrays. It just redeclares them as pointers which
point to the arrays in intel_screen.

Specifically, move these two arrays from brw_context to intel_screen:
    mesa_to_isl_render_format[]
    mesa_format_supports_render[]

And add a new array to intel_screen,

which brw_init_surface_formats() copies to ctx->TextureFormatSupported.

svga: fix pre-mature flushing of the command buffer

When surface_invalidate is called to invalidate a newly created surface
in svga_validate_surface_view(), it is possible that the command
buffer is already full, and in this case, currently, the associated wddm
winsys function will flush the command buffer and resend the invalidate
surface command. However, this can pre-maturely flush the command buffer
if there is still pending image updates to be patched.

To fix the problem, this patch will add a return status to the
surface_invalidate interface and if it returns FALSE, the caller will
call svga_context_flush() to do the proper context flush.
Note, we don't call svga_context_flush() if surface_invalidate()
fails when flushing the screen surface cache though, because it is
already in the process of context flush, all the image updates are already
patched, calling svga_context_flush() can trigger a deadlock.
So in this case, we call the winsys context flush interface directly
to flush the command buffer.

swr: invalidate attachment on transition change

Consider the following RT attachment order:
1. Attach surfaces attachments 0 & 1, and render with them
2. Detach 0 & 1
3. Re-attach 0 & 1 to different surfaces
4. Render with the new attachment

The definition of a tile being resolved is that local changes have been
flushed out to the surface, hence there is no need to reload the tile before
it's written to.  For an invalid tile, the tile has to be reloaded from
the surface before rendering.

Stage (2) was marking hot tiles for attachements 0 & 1 as RESOLVED,
which means that the hot tiles can be written out to memory with no
need to read them back in (they are "clean").  They need to be marked as
resolved here, because a surface may be destroyed after a detach, and we
don't want to have un-resolved tiles that may force a readback from a
NULL (destroyed) surface.  (Part of a destroy is detach all attachments first)

Stage (3), during the no att -> att transition, we  need to realize that the
"new" surface tiles need to be fetched fresh from the new surface, instead
of using the resolved tiles, that belong to a stale attachment.

This is done by marking the hot tiles as invalid in stage (3), when we realize
that a new attachment is being made, so that they are re-fetched during
rendering in stage (4).

Also note that hot tiles are indexed by attachment.

egl/android: Change order of EGLConfig generation (v2)

Many Android apps (such as Google's official NDK GLES2 example app), and
even portions the core framework code (such as SystemServiceManager in
Nougat), incorrectly choose their EGLConfig.  They neglect to match the
EGLConfig's EGL_NATIVE_VISUAL_ID against the window's native format, and
instead choose the first EGLConfig whose channel sizes match those of
the native window format while ignoring the channel *ordering*.

We can detect such buggy clients in logcat when they call
eglCreateSurface, by detecting the mismatch between the EGLConfig's
format and the window's format.

As a workaround, this patch changes the order of EGLConfig generation
such that all EGLConfigs for HAL pixel format i precede those for HAL
pixel format i+1. In my (chadversary) testing on Android Nougat, this

st/mesa: always set sampler swizzle according to the texture base format

Mainly don't (indirectly) call util_format_description here.

If the driver supports texture swizzling, this will always do the right
thing. If the driver doesn't support it, it doesn't matter.

st/mesa: add an entirely separate codepath for setting up buffer views

Remove handling of buffers from all texture paths.

cso: don't track the number of sampler states bound

This removes 2 loops from hot codepaths and adds 1 loop to a rare codepath
(restore_sampler_states), and makes sanitize_hash() slightly worse.

Sampler states, when bound, are not unbound for draw calls that don't need
them. That's OK, because bound sampler states don't add any overhead.

This results in lower CPU overhead in most cases.
