The old python code used sys.is_big_endian to select between little-endian
and big-endian formats, which meant that the build and host endiannesses
needed to be the same. This patch instead generates both big- and little-
endian layouts, using PIPE_ARCH_BIG_ENDIAN to select between them.

_mesa_HashTable is not well-suited for us: it locks a mutex unnecessarily and
it does not accept 0 as the key (and have branches to handle 1 specially).
What we really need is a sparse array. Whether it should be implemented as a
hash table, a list, or a bsearch()-able array requires investigations of the
use models.
We choose to implement it as a list for now, assuming it is common to have a
short list of IDs in each (source, type) namespace. The code is simpler, and
the memory footprint is lower. This also fixes several corner cases such as
making messages to have different states at different severities.

Do not copy the debug group until it is about to be written. One likely
scenario of using glPushDebugGroup/glPopDebugGroup is to enclose a sequence of
GL commands and give them a human-readable description. There is no message
control change in this scenario, and thus no need to copy.
This also reduces the initial size of gl_debug_state from 306KB to 7KB.

copy(): copy all elements from one namespace to another
clear(): clear all elements (to free the memories)

A debug namespace is like a sparse array. The length of the array is huge,

When GL_DEBUG_OUTPUT_SYNCHRONOUS is GL_TRUE, drivers are allowed to log debug
messages from other threads. That requires gl_debug_state to be protected by
a mutex, even when it is a context state. While we do not spawn threads in
Mesa yet, this commit makes it easier to do when we want to.
Since the definition of struct gl_debug_state is no longer needed by the rest
of the driver, move it to main/errors.c. This should make it even harder to
use the struct incorrectly.

GL (3.0) allows you to clear individual color buffers in a fb. In fact
for fbs containing both int and float/normalized color buffers this is
required (because the clearing values are otherwise undefined if applied
to all buffers). The gallium interface was changed a while ago, but llvmpipe
ignored it (hence doing such individual clears always resulted in clearing
all buffers, plus some assorted asserts due to the mixed fbs).
So change the clear command to indicate the buffer to be cleared. Also, because
indicating the buffer to be cleared would have made lp_rast_arg_cmd larger
which is unacceptable (we're trying to shrink it some day) allocate the clear
value in the scene and just pass a pointer.
There's several advantages and disadvantages here:
+ clearing individual buffers works (we could also actually bin such clears now
if they'd come through clear_render_target() if the surface is in the current
fb, though we didn't do this before for the single rb case and still don't try).
+ since there's one clear per rb, we do the format conversion in setup rather
than per bin. Aside from the (drop in the ocean...) performance advantage this
means that clearing to very small values (that is, denormal when converted to
the format) should work for small float (fp16 etc.) formats, as the util code
couldn't handle it correctly before (because cpu denorms are disabled when
executing the bin commands, screwing up the magic conversion and flushing
the values to 0, though this was not verified).
- there's some overhead for traditional old-style clear-all MRT cases, since
there's one rast clear command per rb instead of one for all rbs.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=76976.
v2: get rid of the ugly manual memcpy stuff and just use union util_color.
This is 32 bytes instead of 16 but as the allocation is per scene we can live
with those additional 16 bytes (and the additional 128 bytes in the setup
context), which makes the code much more obvious. Suggested by Brian.
