For enums we were doubling the underscore if the value had a numeric first

This means that with no flatshading we'll emit the single-byte
ZERO_ALL_FLAT_SHADE_FLAGS, and otherwise emit a set of FLAT_SHADE_FLAGS to
get all the bits we need set.

There's a _SET enum in the packet we could use to possibly set entire
ranges of the bitfield without using another packet, but this at least
fixes the conformance failure.

broadcom/vc5: Emit proper flatshading code for glShadeModel(GL_FLAT).

In updating the simulator, behavior changed slightly so that our old code
wasn't getting glxgears's flatshading interpolated right.  Emit flat
shading code just like we would for a normal flat-shaded varying, by
passing a flag in the shader key for glShadeModel(GL_FLAT) state and
customizing the color inputs based on that.

braodcom/vc5: Rely on OVRTMUOUT always being set.

It seems that the HW team has decided that it's the only supported mode,
and it's the mode I actually meant to be using but forgot.  Our table of
return_32_bit should have matched the default non-OVRTMUOUT behavior, so
this change should be invisible.

However, the change revealed that some my return_size checks for swizzling
were a bit confused in the shadow case, so I had to move them to draw time
once we have both the sampler and the view together.

Fixes assertion failures in the updated simulator, where the non-OVRTMUOUT
support has been removed.

broadcom/vc5: Move texture return channel setup into the compiler.

The compiler decides how many LDTMUs we're going to emit, and that must
match the P1 flags.  This brings the return channel counting to a single
place (so all that's passed into the compiler is "how many return channels
you may request from this texture's format), and was a necessary step for
shadow samplers once we stop using OVRTMUOUT=0.

broadcom/vc5: Switch to setting the primitive list format in the RCL.

This means that we get a single copy of it emitted, instead of once at the
start of each tile (though it's still executed once per tile).  Fixes
assertion failures with the updated simulator.

broadcom/vc5: Switch to using the C++ interface for the simulator.

In newer versions they've removed the C interface, so make one here.  This
also isolates the Mesa codebase from the simulator codebase, so we don't
have conflicts over things like "unreachable"

combo is also good for readback of BGRX1010102 framebuffers, not

egl/x11: Handle depth 30 drawables for EGL_KHR_image_pixmap.

Enables eglCreateImageKHR() with target set to
EGL_NATIVE_PIXMAP_KHR to handle color depth 30
X11 drawables.

Note that in theory the drawable depth 32 case in the
current implementation is ambiguous: A depth 32 drawable
could be of format ARGB8888 or ARGB2101010, therefore an
assignment of __DRI_IMAGE_FORMAT_ARGB8888 for a pixmap of
ARGB2101010 format would be wrong. In practice however, the
X-Server (as of v1.19) does not provide any depth 32 visuals
for ARGB2101010 EGL/GLX configs. Those are associated with
depth 30 visuals without an alpha channel instead. Therefore
the switch-case depth 32 branch is only executed for ARGB8888
pixmaps and we get away with this.

Tested with KDE Plasma 5 under X11, DRI2 and DRI3/Present,
selecting EGL + OpenGL compositing and different fbconfigs
with/without 2 bit alpha channel. glxinfo confirms use of
depth 30 visuals for ARGB2101010 only.

egl/x11: Match depth 30 RGB visuals to 32-bit RGBA EGLConfigs.

Similar to the matching of 24 bit RGB visuals to 32-bit
RGBA EGLConfigs, so X11 compositors won't alpha-blend any
config with a destination alpha buffer during compositing.

Additionally this fixes failure to select ARGB2101010
configs via eglChooseConfig() with EGL_ALPHA_BITS 2 on
a depth 30 X-Screen. The X-Server doesn't provide any
visuals of depth 32 for ARGB2101010 configs, it only

not ever get a visual for such a config.

i965: Drop support for the legacy SNORM -> Float equation.

Older OpenGL defines two equations for converting from signed-normalized
to floating point data.  These are:

    f = (2c + 1)/(2^b - 1)                (equation 2.2)
    f = max{c/2^(b-1) - 1), -1.0}         (equation 2.3)

Both OpenGL 4.2+ and OpenGL ES 3.0+ mandate that equation 2.3 is to be
used in all scenarios, and remove equation 2.2.  DirectX uses equation
2.3 as well.  Intel hardware only supports equation 2.3, so Gen7.5+
systems that use the vertex fetcher hardware to do the conversions
always get formula 2.3.

This can make a big difference for 10-10-10-2 formats - the 2-bit value
can represent 0 with equation 2.3, and cannot with equation 2.2.

Ivybridge and older were using equation 2.2 for OpenGL, and 2.3 for ES.
Now that Ivybridge supports OpenGL 4.2, this is wrong - we need to use
the new rules, at least in core profile.  That would leave Gen4-6 doing
something different than all other hardware, which seems...lame.

With context version promotion, applications that requested a pre-4.2
context may get promoted to 4.2, and thus get the new rules.  Zero cases
have been reported of this being a problem.  However, we've received a
report that following the old rules breaks expectations.  SuperTuxKart
apparently renders the cars red when following equation 2.2, and works
correctly when following equation 2.3:

https://github.com/supertuxkart/stk-code/issues/2885#issuecomment-353858405

So, this patch deletes the legacy equation 2.2 support entirely, making
all hardware and APIs consistently use the new equation 2.3 rules.

If we ever find an application that truly requires the old formula, then
we'd likely want that application to work on modern hardware, too.  We'd
likely restore this support as a driconf option.  Until then, drop it.

This commit will regress Piglit's draw-vertices-2101010 test on
pre-Haswell without the corresponding Piglit patch to accept either
formula (commit 35daaa1695ea01eb85bc02f9be9b6ebd1a7113a1):

    draw-vertices-2101010: Accept either SNORM conversion formula.

meta: Don't pollute the texture 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.
