Using BEGIN_BATCH can lead to a nice inf recursion through require_space
-> flush_batch -> BEGIN_BATCH.
Also fix things up to always require BATCH_RESERVED. We need 2 dwords
for the gen5 workaround and 2 dwords for MI_BB_END.
Assures that signals interrupting the wait works properly. Because of
the scheduling around signals, interrupted waits will *seem* faster as
the GPU continues to work while all the CPU scheduling stuff happens.

We should get more kms tests soon, and not needing to copy-paste a
nice test pattern should be useful.
That establishes a firm depency of i-g-t on cairo over everything, but
I don't care so much about that.

The path isn't properly autodetected and it yells stupid stuff into
stderr. Which causes spurious failures.
And really, these are automated tests. If you need to look at the output,
something is wrong.

Somehow nobody noticed this before, but we were missing blt and bsd6
initialization on Gen7.

It optimized away the read loops ;-)
Also fix up the size to not be 1/4th of the one we want for tiled
buffer tests.

For now, only print their content for diffing, but also add the necessary
bits that can be used for more verbose output in the fugure.

Unfortunately this requires slab poisoning to catch anything :(
Also add a new helper to drmtest to get the available fence count.

Now with more tiling transition tests. Changes:
- refactoring to reuse the tiling transition functions.
- add a tiled->untiled transition
- add a tiled->tiled transition with different stride
- add a check at the end to ensure that the tiling has indeed changed
on the test_bo

This is a command-line tool that allows us to display and modify the
InfoFrames we send.

Although the address space for GTT mappings may only be 32-bits, we need
to use the explicit 64-bit mmap interface so that on a 32-bit platform
the offset we pass is not truncated to 31-bits.
Fixes gem_mmap_offset_exhaustion on 32-bit platforms.
