radeonsi: Do colorformat endian swap for PIPE_USAGE_STAGING

There is an old if statement (dated to 2011) that prevented doing
endian swap for colorformat, in case the buffer is marked as
PIPE_USAGE_STAGING.

This is now wrong because st_ReadPixels() reads into a destination
texture that is marked with PIPE_USAGE_STAGING. Therefore, even if
the texture is rendered correctly to the monitor, when reading it
back we get unswapped/wrong values.

This patch makes the check_rgba() function in gl-1.0-readpixsanity
piglit test pass in big-endian.

i965/meta: Don't pollute the framebuffer namespace

In OpenGL ES (all versions!) and OpenGL compatibility profile,

Some meta operations can be called recursively.  Future changes (the
"Don't pollute the ... namespace" changes) will cause objects with
invalid names to be used.  If a nested meta operation tries to restore

This also fixes another latent bug in meta.  In a multithreaded,
multicontext application, one thread can delete an object that is bound
in another thread.  That object continues to exist until it is unbound
(i.e., its refcount drops to zero).  Meta unbinds objects all over the
place.  As a result, the rebind in _mesa_meta_end could fail because the
object vanished!

See https://bugs.freedesktop.org/show_bug.cgi?id=92363#c8.

i965: Push most TES inputs in vec4 mode.

(This is commit 4a1c8a3037cd29938b2a6e2c680c341e9903cfbe for vec4 mode.)

Using the push model for inputs is much more efficient than pulling
inputs - the hardware can simply copy a large chunk into URB registers
at thread creation time, rather than having the thread send messages to
request data from the L3 cache.  Unfortunately, it's possible to have
more TES inputs than fit in registers, so we have to fall back to the
pull model in some cases.

However, it turns out that most tessellation evaluation shaders are
fairly simple, and don't use many inputs.  An arbitrary cut-off of
24 vec4 slots (12 registers) should suffice.  (I chose this instead of
the 32 vec4 slots used in the scalar backend to avoid regressing a few
Piglit tests due to the vec4 register allocator being too stupid to
figure out what to do.  We probably ought to fix that, but it's a
separate issue.)

Thread 1: writes data
Thread 1: Unlock

Without this patch, the buffer is initially dirty
and in the list of things to upload after its creation.
The draw call will then upload the data and unset the dirty flag,
and the Unlock won't trigger a second upload.

Fixes regression introduced by cc0114f30b587a10766ec212afb3ad356099ef23:

st/nine: Fix Multithreading issue with MANAGED buffers

d3d calls are protected by mutexes, however if app is doing in
two threads:

Thread 1: buffer Lock
Thread 2: Draw call
Thread 1: writes data
Thread 1: Unlock

Then before this patch, the Draw call would begin to upload
the buffer.

Solves this by moving the moment we add the buffer to the queue
of things to upload (We move it from Lock time to Unlock time).

r600: Make enum alu_op_flags unsigned

In builds with clang, there are several errors related to the enum

Since the rework on gallium pipe formats, there is no more need to do
endian swap of the colorformat in the h/w, because the conversion between
mesa format and gallium (pipe) format takes endianess into account (see
