Currently we have two sets of functions for bit counts, one in gallium
and one in core mesa. The ones in core mesa are header only in many
cases, since they reduce to "#define _mesa_bitcount popcount", but they
provide a fallback implementation. This is important because 32bit msvc
doesn't have popcountll, just popcount; so when nir (for example)
includes the core mesa header it doesn't (and shouldn't) link with core
mesa. To fix this we'll promote the version out of gallium util, then
replace the core mesa uses with the util version, since nir (and other
non-core mesa users) can and do link with mesautils.

Now that all the build scripts are compatible with both Python 2 and 3,
we can flip the switch and tell Meson to use the latter.
Since Meson already depends on Python 3 anyway, this means we don't need
two different Python stacks to build Mesa.

I missed an important part when porting the change over, fixing my
compiler warning but breaking -Werror=format-security.

These will match the names that the CLIF parser expects to see. I may in
the future decide to change more of the other names so that I match the
names the HW/closed SW team uses for their packets, rather than the names
in the spec (which only they and I can read anyway).
This matches what CLIF parsing expects, and makes
TILE_BINNING_MODE_CONFIGURATION_COMMON_CONFIGURATION into a much more
legible TILE_BINNING_MODE_CFG_COMMON.
The CLIF format expects american english spelling, and the rest of Mesa is
too. I was previously adhering to the spec's spelling, which is
counterproductive.
V3D only has one of these (the top 16 bits of a float32) left in its CLs,
but VC4 had many more. This gets us proper pretty-printing of the values
instead of a large uint.
Previously, we emitted in XML order, which I happen to type in the
decreasing offset order of the specifications. However, the CLIF parser
wants increasing offsets.
With CLIFs, the parser will choose an address for the buffer being
created, so we need to use effectively relocations to buffers instead of
the addresses that the driver uses. This is also a whole lot more
intelligible for console output than raw addresses!
To generate CLIF files that the v3dv3 simulator can parse, we're going to
need to decode addresses, and for that we'll need the vaddr lookup
function from the clif structure from within v3d_decoder.
This reflects a change on the HW/closed SW side to drop this unused HW.
With it dropped on their side, the CLIF parser no longer expects to find
VG fields.
Python 2 has a range() function which returns a list, and an xrange()
one which returns an iterator.
Python 3 lost the function returning a list, and renamed the function
returning an iterator as range().
As a result, using range() makes the scripts compatible with both Python
versions 2 and 3.

We weren't using the field yet, so it didn't affect anything.
Fixes: c0476d964a ("v3d: Express dithering mode in the same way that the CLIF parser does.")
We were overlapping it with the threadable/nan flags, resulting in
incorrect relocations (threadable/nan included in the offset) and wrong
ordering in the CLIF files.
The XML ends up noisier if you're only looking at one version, but from
the diffstat there's obvious wins in terms of deduplication. This will
get even more significant if we ever support 3.2 or 4.0.
The XML zipper wants one XML per version for filling out its tables, but
we want to do more than one GPU version per XML now. Assume that the
"gen" field will be the same as min_ver and look up our XML text assuming
that they're listed in increasing min_ver.
It turns out that most V3D versions change very few packets, so keeping
separate copies of the XML per version makes changing the XML a pain as
you have to replicate your changes to each one. This is the start of
changing it so that one XML can generate headers for multiple versions.
Right now, we name these fields as "field name minus one" so that your C
code obviously states what the value should be. However, it's easy enough
to handle at the codegen level with another little XML attribute, meaning
less C code and easier-to-read values in CLIF dumping and gdb as well.
(The actual CLIF format for simulator and FPGA replay takes in
pre-minus-one values, so we need it there too).
For a meson -Db_ndebug=true release build on x86_64, reduces text size of
libv3d.a from 53.0k to 51.6k. Inspired by 0d5329d626 ("anv: Disable
__gen_validate_value if NDEBUG is set.")
You'd need src/broadcom/cle/ in the -I previously, for srcdir != builddir.
nir was fine at that, but automake didn't have it.

We try to emit a #error and continue so that you can debug the missing
type at C compile time, but were missing a couple of definitions in that
path (sigh, python).
