Since the last patched value does not match the presumed relocation
value we submit to the kernel, it occasionally makes mistakes. Also note
that the libdrm interface makes the same presumptive mistake, and would
easily be broken by a threaded environment.

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
tests, we also now double check that we do not use more batch space than
declared.

And shovel all the various helpers in there.
Also move igt_set_vt_graphics_mode to igt_kms.h since the function is
implemented in igt_kms.c. And it fits better. I kinda missed this in
the prep work.

With the header cleanup we can now give this header a suitable name,
since it now really only contains register access and other I/O
functions and assorted definitions.

NOTE: Some subtests are still failing, but I haven't found the bug yet.
At least this should help QA meanwhile.

This provides a macro that allows us to update all the arbitrary blit
commands we have stuck throughout the code. It assumes we don't actually
use 64b relocs (which is currently true). This also allows us to easily find
all the areas we need to update later when we really use the upper dword.
This block was done mostly with a sed job, and represents the easier
in test blit implementations.

This is basically a "drop cache" interface to the igt_debugfs
facilities. Also, update existing users.

A typo in the relocation tests made both sub-tests perform the
same action: drop *all* caches.

In the past new testcases with subtest often forgot to add the call to
igt_exit at the end of their main() function. That is now caught with
a bit more obnoxious asserts, but it's still a nuissance.
This little igt_main macro takes care of that (and also of calling the
subtest machinery initialization code correctly).
If no one objects I'll roll this out for all the simple cases (i.e.
those tests that don't have additional argv parsing on top of the
subtest machinery).
v2: Roll it out across the board.

With the new _f variants we can replace almost all of them.
Also remove a ton of checks for argc != 1, they're a bit useless ...

- Clear the igt_helper_process struct to avoid hitting asserts.
- Fix up the logic for enumerating forked processes.

Mostly a sed job with too manual fixups:
- one case of using _exit instead of exit
- and one case which under some conditions use 77, so convert that
check to an igt_skip.

Let's start by a small set of tests, to eventually consider running
more.
The current list should then be:
gem_mmap
gem_pread_after_blit
gem_ring_sync_loop
gem_ctx_basic
gem_pipe_control_store_loop
gem_storedw_loop_render
gem_storedw_loop_blt
gem_storedw_loop_bsd
gem_render_linear_blits
gem_tiled_blits
gem_cpu_reloc
gem_exec_nop
gem_mmap_gtt
v2 add (Daniel Vetter)
gem_exec_bad_domains
gem_exec_faulting_reloc
gem_flink
gem_reg_read
gem_reloc_overflow
gem_tiling_max_stride
prime_*

- fixup pitch mess noticed by Chris Wilson.
- we need to diable bo reuse otherwise the kernel won't do the relocs
(we might get an already gtt-bound batch from the dummy load).
