Add helper to scan the CP_INDIRECT_BUFFERs, and then work backwards
accounting for data buffered via ROQ prefetch to deduce the actual
SQE position at the time of the crash.

We were previously checking only every 8 dwords within the packet. We
should instead just check if the hang location comes within the packet.

This was causing us to use the size of the previous packet. Which just
happened to land on a valid packet because pkt2 only followed a
CP_INDIRECT_BUFFER.

I have multiple examples where this register is too large by one
when comparing to the ROQ read/write pointers in CP_ROQ_*_STAT and the
ROQ data itself, as if it includes the dword most recently read too. I
have an example where it's off by 2 compared to the read pointer, but
the read pointer is also off by 1 itself judging by the SQE program
counter, so that may just be them not getting synchronized. This
off-by-one was getting in the way of figuring out exactly IB2 was being
processed in the next commit.

These don't correspond to the a3xx *_STAT registers, which we're about
to add so we need to rename them. The closest analogue is CP_CSQ_AVAIL,
although the sense is inverted (and we're not sure what the low 16 bits
are about). Also, the a3xx distinction between CSQ and STQ doesn't exist
anymore so don't use these outdated terms.

The offsets table stores offsets of a buffer (such as cmdstream) that
we've already dumped. The suballoc pool results in more suballocated
cmdstream allocated from a single backing buffer, meaning that we need
to increase the size of this table.

We can end up logging both the buffer that the toplevel cmdstream is
allocated, as well as the sub-allocated part of that buffer. Possibly
the kernel could do better about this, but to avoid undecodeable
cmdstream dumps and devcores, detect this case and deal with it.

The source code for rddecompiler includes adreno_common.xml.h, which is
a generated header. In order to ensure that the header has been written
when compiling rddecompiler.c, we need a dependency here.

Decompiles a single cmdstream from .rd into compilable C source.
Given the address space bounds the generated program creates
a new .rd which could be used to override cmdstream with 'replay'.
Generated .rd is not replayable on its own and depends on buffers
provided by the source .rd.

This adds an option to override a single cmdstream while replaying
.rd capture. Cmdstream for override is stored in the same .rd format,
where there is only one RD_CMDSTREAM_ADDR section and any amount
of buffers.
Instead of using provided .rd file, 'replay' calls external program
to generate it first, in order to be able to pass the range of
GPU addresses available for the new buffers.
Usage example:
./replay --override=13 --generator=~/cmdstream_gen

source_root() function is deprecated in Meson version 0.56.0 because
it returns the source root of the parent project if called from a
subproject.
Why would anyone need Mesa as a meson subproject?
It would be used as subproject in a project generated by command buffer
"decompiler" for Freedreno.

Replay command stream obtained from:
- /sys/kernel/debug/dri/0/rd
- /sys/kernel/debug/dri/0/hangrd
!!! Command stream capture should be done with ALL buffers:
- echo 1 > /sys/module/msm/parameters/rd_full
Requires kernel with MSM_INFO_SET_IOVA support.
This tool is intended for reproduction of various GPU issues:
- GPU hangs, note that command stream obtained from hangrd
may not reproduce (rarely) the hang, since the buffers are
snapshotted at the moment of the hang and not at the start
of the hanging command stream.
- TODO: Misrendering, would require marking framebuffer images
at each renderpass in order to fetch and decode them.
Code from Freedreno/Turnip is not re-used here since the relevant
pieces may introduce additional allocations which cannot be allowed
during the replay.

The default lib prefix is `lib`, so adding `lib` to the lib name just
results in `liblibbroadcom_v3d.a` for instance.
Those are internal, build-temporary static libraries that end up being
linked into the real user-visible libraries, so it doesn't really
matter, but we might as well just clean up their names anyway.

Since these were reverse-engineered, it's become clear that IBO
descriptors are just a subset of texture descriptors, and bindless reads
of readonly images actually use isam on the IBO descriptor, further
confirming that the two are always compatible, even if not all of the
texture fields exist for IBOs. It's pointless to have a separate type
for IBOs, and just leads to things getting out-of-sync unnecessarily
which has already happened. Just remove it and use TEX_CONST insted.

We no longer have reg defs for the HI fields, so all we can access from
lua is the low 32 bits. LUA has only double-precision floats for numbers,
so we can't fix that. However, the high bits are almost always the same,
so it's not that big of a deal to be ignoring them for this script.

Now they run automatically in parallel with other unit testing, rather
than needing a separate script and environment to run them.
Instead of doing shell script filtering afterwards, I just added a little
flag to suppress printing the path name. Also dropped the "Parsing
<file>" in addition to "Reading <file>" in the tested script, since it's
redundant and baked the path name into the reference.
