As we use chained batch into itself to hang the gpu, there
was no need to end the batchbuffer with BATCH_BUFFER_END.
With the introduction of command parser, the batch
need to have proper BATCH_BUFFER_END in it or it
will be rejected.
While at it, shift the upper half of batch gtt_offset
accordingly with gen8+

To gain more coverage on interface, default context and banning.
As there is no proper reset support for gen <= 3, we only
do limited interface testing on those.

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.

And move the public interfaces into intel_batchbuffer.[hc].
A bit messy since we are fairly inconsistent with our header #include
handling.
Also exclude rendercopy.h from the documentation.

Tests _must_ be able to run as non-root and on non-intel platforms,
otherwise the enumeration is busted (since QA enumerates testcases on
a gpu-less xeon box).

If we stop all the rings, we can end up blaming the innocent
rings on hangcheck.

Use own copy of gem_quiescent_gpu() so that test still works
if it gets changed. Further improve the test by posting a batch
to rings in reverse order.

For BDW+, there BATCH_BUFFER_START is 3 * 32bits in length and
length needs to be encoded into the opcode.
