drm/i915: Explicitly track DRM clients
Tracking DRM clients more explicitly will allow later patches to
accumulate past and current GPU usage in a centralised place and also
consolidate access to owning task pid/name.
Unique client id is also assigned for the purpose of distinguishing/
consolidating between multiple file descriptors owned by the same process.
v2:
Chris Wilson:
* Enclose new members into dedicated structs.
* Protect against failed sysfs registration.
v3:
* sysfs_attr_init.
v4:
* Fix for internal clients.
v5:
* Use cyclic ida for client id. (Chris)
* Do not leak pid reference. (Chris)
* Tidy code with some locals.
v6:
* Use xa_alloc_cyclic to simplify locking. (Chris)
* No need to unregister individial sysfs files. (Chris)
* Rebase on top of fpriv kref.
* Track client closed status and reflect in sysfs.
v7:
* Make drm_client more standalone concept.
v8:
* Simplify sysfs show. (Chris)
* Always track name and pid.
v9:
* Fix cyclic id assignment.
v10:
* No need for a mutex around xa_alloc_cyclic.
* Refactor sysfs into own function.
* Unregister sysfs before freeing pid and name.
* Move clients setup into own function.
v11:
* Call clients init directly from driver init. (Chris)
v12:
* Do not fail client add on id wrap. (Maciej)
v13 (Lucas): Rebase.
v14:
* Dropped sysfs bits.
v15:
* Dropped tracking of pid/ and name.
* Dropped RCU freeing of the client object.
