Changes in v4:
  - Remove mention of vague "dma_fence rules" in timedout_job() again
    since I couldn't get input on what those rules precisely are.
  - Address a forgotten TODO. (Me)
  - Reposition "Return:" statements to make them congruent with the
    official kernel style. (Tvrtko)
  - Change formatting a bit because of crazy make htmldocs errors. (Me)

Changes in v3:
  - timedout_job(): various docu wording improvements. (Danilo)
  - Use the term "ring" consistently. (Danilo)
  - Add fully fledged docu for enum drm_gpu_sched_stat. (Danilo)

Changes in v2:
  - Document what run_job() is allowed to return. (Tvrtko)
  - Delete confusing comment about putting the fence. (Danilo)
  - Apply Danilo's RB to patch 1.
  - Delete info about job recovery for entities in patch 3. (Danilo, me)
  - Set the term "ring" as fix term for both HW rings and FW rings. A
    ring shall always be the thingy on the CPU ;) (Danilo)
  - Many (all) other comments improvements in patch 3. (Danilo)

This is as series succeeding my previous patch [1].

I recognized that we are still referring to a non-existing function and
a deprecated one in the callback docu. We should probably also point out
the important distinction between hardware and firmware schedulers more
cleanly.

Please give me feedback, especially on the RFC comments in patch3.

(This series still fires docu-build-warnings. I want to gather feedback
on the opion questions first and will solve them in v2.)

Thank you,
Philipp
