For good performance while being able to generate decent hang reports.
The report doesn't contain the parsed IB and the buffer list, but it
isolates the draw call and dumps shaders while not having to flush
the context.

This is for GPU hangs that are harder to reproduce and require interactive
playing for minutes or even hours.

dd_pipe.h explains some implementation details. Initializing, copying
(recording) and clearing states is most of the code.

The performance should be at least 50% of the normal performance depending
on the circumstances. (i.e. 50% is expected to be the worst case scenario,
not the best case) The majority of time is spent in
dump_debug_state(PIPE_DUMP_CURRENT_SHADERS) and that's after all
the optimizations in later patches. There is no obvious way to optimize
that further.

Make them akin to shader buffers, with no refcounting/etc. Just used to
pass data about the bound image in ->set_shader_images.

This currently just writes out the name of dump files, which can be useful
to easily correlate those files with other log outputs (driver debug output,
apitrace calls, etc.)

When we know that hangs occur only very late in a reproducible run (e.g.
apitrace), we can save a lot of debugging time by skipping the flush and hang
detection for earlier draw calls.

v2: lots of improvements

This is like identity or trace, but simpler. It doesn't wrap most states.

Run with:
GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.

If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
/home/$username/dd_dumps/$processname_$pid_$index.

Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.

You can also do:
GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.

Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.

v2: drop pipe-loader changes, drop SConscript
rename dd.h -> dd_pipe.h
