[0/4] drm/i915: uAPI clean-ups part 2

This patch series is the second installment of my quest to clean up the
i915 uAPI.  The first three patches delete interfaces which have only ever
been used by i-g-t and never any real userspace.  In the case of NO_ZEROMAP,
it's unclear exactly how this happened.  There were userspace patches for
it back in the day, they just never landed.  For the others, there was
never any userspace beyond i-g-t and they never should have landed in the
first place.

The last patch moves the SINGLE_TIMELINE API to an emulation using syncobj
to help simplify some of our locking infrastructure.

Test-with: [e-mail]
