Gen7+ has per-stage sampler state pointer update packets, so we emit

we have a single packet, so we delay until we've changed everything

When the driver was originally written, it only supported texturing in
the pixel shader backend; vertex and geometry shader texturing came much
later. Originally, the pixel shader was referred to as "WM" (the
Windowizer/Masker unit). So, this code happened to only be relevant for
the WM stage, at the time.
However, sampler state really applies to all stages, so putting "wm" in
the filename doesn't make sense. I dropped it in gen7_sampler_state.c;
at this point the asymmetry just trips people up.

When using (d3d10) conformant out-of-bound behavior for texel fetching
(currently always enabled) the level still needs to be set to a safe value
even though the offset in the end won't get used because the level is used
to look up the mip offset itself and the actual strides, which might otherwise
crash.
For simplicity, we'll use level 0 in this case (this ought to be safe, llvmpipe
does not actually fill in level 0 information if first_level is larger, but
some random strides / offsets shouldn't hurt as ultimately we always use
offset 0 in this case).

The kms-dri swrast driver cannot share buffers using the GEM,
so it must tell the loader to disable extensions relying on
that, without disabling the image DRI extension altogether
(which would prevent the loader from working at all).
This requires a new gallium capability (which is queried on
the pipe_screen and for swrast drivers it's forwarded to the
winsys), and requires a new version of the DRI image extension.

We've had bugs in the past where we have been inadvertently matching the

Just as we did in the pre-processor in the previous commit, we can use:
%option warn nodefault
in the compiler to instruct flex to not generate the default rule, and
further to warn if our set of rules could let any characters go unmatched.
With this warning active, flex actually warns that the catch-all rule we
recently added to the compiler could never be matched. Since that is all
safely determined at compile time now, we can safely drop this run-time
compiler error message, (as we do in this commit).

We've had multiple bugs in the past where we have been inadvertently matching
the default rule, (which we never want to do). We recently added a catch-all
rule to avoid this, (and made this rule robust for future start conditions).
Kristian pointed out that flex allows us to go one step better. This syntax:
%option warn nodefault
instructs flex to not generate the default rule at all. Further, flex will
generate a warning at compile time if the set of rules we provide are
inadequate, (such that it would be possible for the default rule to be
matched).
With this warning in place, I found that the catch-all rule was in fact
missing something. The catch-all rule uses a pattern of "." which doesn't
match newlines. So here we extend the newline-matching rule to all start
conditions. That is enough to convince flex that it really doesn't need
any default rule.

In some of the recent glcpp bug-fixing, we found that glcpp was emitting
unrecognized characters from the input source file to stdout, and dropping
them from the source passed onto the compiler proper.
This was obviously confusing, and totally undesired.
The bogus behavior comes from an implicit default rule in flex, which is
that any unmatched character is implicitly matched and printed to stdout.
To avoid this implicit matching and printing, here we add an explicit
catch-all rule. If this rule ever matches it prints an internal compiler
error. The correct response for any such error is fixing glcpp to handle
the unexpected character in the correct way.

Previously, the '\r' character was not explicitly matched by any lexer
rule. This means that glcpp would have been using the default flex rule to
match '\r' characters, (where they would have been printed to stdout rather
than actually correctly handled).
With this commit, we treat '\r' as equivalent to '\n'. This is clearly an
improvement the bogus printing to stdout. The resulting behavior is compliant
with the GLSL specification for any source file that uses exclusively '\r' or
'\n' to separate lines.
For shaders that use a multiple-character line separator, (such as "\r\n"),
glcpp won't be precisely compliant with the specification, (treating these as
two newline characters rather than one), but this should not introduce any
semantic changes to the shader programs.

This test is written to exercise a bug which I recently wrote, (but
fortunately caught and fixed before ever committing it).
For the curious:
The bug happened when the NEWLINE_CATCHUP code didn't actually return the
NEWLINE token (due to the skipping). This resulted in the lexer continuing
on through all the subsequent rules while still in the NEWLINE_CATCHUP start
condition, (which then triggered the internal-compiler-error catch-all
rule).
What is intended is for the return of the NEWLINE token to start a new
iteration of the lexer loop, at which time the NEWLINE_CATCHUP-handling code
will reset from the <NEWLINE_CATCHUP> to the <INITIAL> start condition.

These operators aren't defined for preprocessor expressions, so we never
implemented them. This led them to be misinterpreted as strings of unary

In fact, what is actually desired is to generate an error if these operators
appear in any preprocessor condition.
So this commit looks like it is strictly adding support for these
operators. And it is supporting them as far as passing them through to the
subsequent compiler, (which was already happening anyway).
What's less apparent in the commit is that with these tokens now being lexed,
but with no change to the grammar for preprocessor expressions, these
operators will now trigger errors there.
