[PATCH v3 00/22] Refactor VM bind code

[Matthew Brost <matthew.brost@intel.com>]

Implement proper error handling for VM bind IOCTL by allowing failures
of GPU memory allocation (either system or VRAM) to be propagated to
user without corrupting VM state. Mainly implemented by converting VM
bind IOCTL to 1 job per IOCTL rather than potential many jobs.

Broken into roughly 4 parts:
Part 1: Prep patches, patches 1-11
Part 2: 1 jobs per VM bind IOCTL and error handling, patches 12-17
Part 3: CPU binds, patches 18-21
Part 4: Error injection for testing, patch 22

For reviewing, let's focus on part 1 for now and see if patches from
that part can start to get merged.

Tested with [1] and new error handling appears to be working. Also
tested with existing tests at every patch in the series and should be
working at every patch in the series.
