- Make the domain scheduler timeslice type nanoseconds to future proof
the interface
- Return -ENOSYS from ioctls if the nvs code is not initialized
- Return the number of domains also when user supplied array is present
- Use domain id instead of name for TSG binding
- Improve documentation in the uapi headers
- Verify that reserved fields are zeroed
- Extend some internal logging
- Release the sched mutex on alloc error
- Add file mode checks in the nvs ioctls. The create and remove ioctls
require writable file permissions, while the query does not; this
allows filesystem based access control on domain management on the
single dev node.

GVS: Gerrit_Virtual_Submit
Add software scheduler and domain data structures for a general
scheduler and bookkeeping code to create, remove and list them and to
keep logs for debugging and development; as a first step, this will only
serve as the heart of nvgpu-internal domain scheduler.
Long term, this code is intended to work in arbitrary configurations -
running on GSP, CPU, or elsewhere, and controlling the GPU or something
else.
