i965/meta: Don't pollute the framebuffer namespace
tl;dr: For many types of GL object, we can *NEVER* use the Gen function.
In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions. The GL spec is very
clear about how you can mix-and-match generated names and non-generated
names: you can use any name you want for a particular object type until
you call the Gen function for that object type.
Here's the problem scenario:
- Application calls a meta function that generates a name. The first
Gen will probably return 1.
- Application decides to use the same name for an object of the same
type without calling Gen. Many demo programs use names 1, 2, 3,
etc. without calling Gen.
- Application calls the meta function again, and the meta function
replaces the data. The application's data is lost, and the app
fails. Have fun debugging that.

meta: Save and restore the framebuffer using gl_framebuffer instead of GL API object handle
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
an object named 0xDEADBEEF, it will fail.
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.
Using _mesa_reference_<object type> to save and restore the objects
prevents the refcount from going to zero.

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.)

This produces IR like
(loop (

can I unroll this?"
We can detect this another way. If there is no limiting_terminator

On my very old checkout of shader-db, this removes a loop from Orbital

from a non-existant front color buffer. The front color buffer is
created on demand in st/mesa. Since the missing buffer bounds were
effectively 0 x 0 the glReadPixels was totally clipped and returned
early.
The fix involves creating the real front color buffer when we're about
to try reading from it.
Tested with llvmpipe and VMware driver on Linux, Windows.

gallium/radeon: Correctly translate colorswaps for big endian
The current code in r600_translate_colorswap uses the swizzle information
to determine which colorswap to use.
This works for BE & LE when the nr_channels is <4, but when nr_channels==4
(e.g. PIPE_FORMAT_A8R8G8B8_UNORM), this method can not be used for both BE
and LE, because the swizzle info is the same for both of them.
As a result, r600g doesn't support 24bit color formats, only 16bit, which
forces the user to choose 16bit color in X server.
This patch fixes this bug by separating the checks for LE and BE and
adapting the swizzle conditions in the BE part of the checks.
Tested on an Evergreen GPU (Cedar GL FirePro 2270) running inside POWER7
Big-Endian Machine.

mesa: use sizeof on the correct type
Before the luminance stride was based on the size of GL_FLOAT
which is just the type constant (0x1406). Change it to use the
size of GLfloat.
