Move create_stereo_fb from testdisplay to igt_create_stereo_fb in igt_fb
so that it can be used in other tests.
v2: update for new igt_create_fb API
add parameters for format and tiling

Instead of building batch directly to memory, build into cmd and
state arrays. This representation allows us more flexibility in batch
state expression and batch generation/relocation.
As a bonus, we can also attach the line information that produced the
batch data to help debugging.
There is no change in the output states produced. This can be considered
as a preparatory patch to help introduce gen8 golden state.

- Use keys in just one env variable to enable/disable it.
- Add an informational message so that the users knows when to press
the key (more useful over ssh than when run on the terminal ofc).
- Improve the documentation so that it's clearer how to use this
when running tests.

If we don't reset exit_handler_count before forking, we may have a
case where the forked process is killed before it even does
"exit_handler_count = 0": in that case, it is still finishing forking.
When that happens, we may end up calling our exit handlers. On the
specific bug I'm investigating, we call igt_reset_connnectors(), which
ends up in a deadlock inside malloc_atfork. If we attach gdb to the
forked process and get a backtrace, we have:

After doing some searches for "stuck at malloc_atfork", it seems to me
we probably shouldn't be doing any malloc calls at this point of the
code, so the best way to do that is to make sure we can't really run
the exit handlers.
So on this patch, instead of resetting the exit handlers after
forking, we reset them before forking, and then restore the original
value on the parent process.
I can reproduce this problem by running "./kms_flip --run-subtest
2x-flip-vs-modeset" under an infinite loop. Usually after a few
hundred calls, we end up stuck on the deadlock mentioned above. QA
says this problem happens every time, but I'm not sure what is the
difference between our environments that makes the race condition so
much easier for them.
The kms_flip.c problem can be considered a regression introduced by:
commit eef768f283466b6d7cb3f08381f72ccf3951dc99
Author: Thomas Wood <thomas.wood@intel.com>
Date: Wed Jun 18 14:28:43 2014 +0100
tests: enable extra connectors in kms_flip and kms_pipe_crc_basic
even though this commit is not the one that introduced the real
problem.
It is also possible to reproduce this problem with a few modifications
to template.c:
- Add a call to igt_enable_connectors() inside the first fixture.
- Add igt_fork_signal_helper() and igt_stop_signal_helper() calls
around subtest B.
Note that the crucial piece is that the parent actively kills helper
children, and if we skip tests this can happen _really_ fast. See e.g.

Since relocations are variable size, depending upon generation, it is
easier to handle the resizing of the batch request inside the
BEGIN_BATCH macro. This still leaves us with having to resize commands
in a few places - which still need adaption for gen8+.

This reveal that quite a few locations were writing relocation offsets
but only allowing for 32 bit addresses. To reveal such places in active

declared.

Some of the workarounds are lost followed by a gpu reset, suspend/resume;
this patch adds a test which compares register state before and after
