[Mesa-dev] [PATCH] panfrost: Add pandecode (command stream debugger)

The `panwrap` utility can be LD_PRELOAD'd into a GLES app, intercepting
communication between the driver and the kernel. Modern panwrap versions
do no processing of their own; instead, they create a trace directory.
This directory contains the following files:
- control.log: a line-by-line plain text file, denoting important
syscalls (mmaps and job submits) along with their arguments
- memory_*.bin, shader_*.bin: binary dumps of mapped memory
Together, these files contain enough information to reconstruct the
command stream and shaders of (at minimum) a single frame.
The `pandecode` utility takes this directory structure as input,
reconstructing the mapped memory and using the job submit command as an
entrypoint. It then walks the descriptors as the hardware would, parsing
and pretty-printing. Its final output is the pretty-printed command
stream interleaved with the disassembled shaders, suitable for driver
debugging. For instance, the behaviour of two driver versions (one
working, one broken) can be compared by diff'ing their decoded logs.
pandecode/decode.c was originally a part of `panwrap`; it is the oldest
living code in the project. Its history is generally not worth
preserving.
panwrap itself will continue to live downstream for the foreseeable
future, as it is specifically written for the vendor kernel. It should
be simple, however, to produce equivalent traces directly from Panfrost,
bypassing the intermediate wrapping layer for well-behaved drivers.
