Now that the main nvsched code exists in the nvgpu build, make it
control the runlist domains. As a new nvs domain is created, create the
relevant runlist data too. To support the default domain, create a
default nvs domain at boot.
The scheduling domain code owns the responsibility of domain lifetime,
and runlist domains exist to serve that logic although the RL domains
are directly used by channel and TSG logic. Add refcounting to the
scheduler uapi level to make sure that busy domains (that still have TSG
participants) do not get removed too early.
Adjust error injection sensitive unit tests to match the updated logic.

The NEXT bit can remain set for the channel if timeslice expires before
scheduler clears it. Due to this nvgpu fails TSG unbind and in turn
nvrm_gpu fails channel close. In this case, checking the channel hw
state after some time can help see NEXT bit cleared by scheduler.
Reenable the tsg and return -EAGAIN to nvrm_gpu for it to retry again.

Make Recovery and quiesce co-exist to support quiesce state
on unrecoverrable errors. Currently, the quiesce code is wrapped
under ifndef CONFIG_NVGPU_RECOVERY. Isolate the quiesce code from
recovery config, thereby enabling it on all builds.
On Linux, the hung_task checker(check_hung_uninterruptible_tasks()
in kernel/hung_task.c) complains that quiesce thread is stuck for
more than 120 seconds.
INFO: task sw-quiesce:1068 blocked for more than 120 seconds.
The wait time of more than 120 seconds is expected as quiesce
thread will wait until quiesce call is triggered on fatal
unrecoverable errors. However, the INFO print upsets the
kernel_warning_test(KWT) on Linux builds. To fix the failing
KWT, change the quiesce task to interruptible instead of
uninterruptible as checker only looks at uninterruptible tasks.

Refactor user managed syncpoints out of the channel sync infrastructure
that deals with jobs submitted via the kernel api. The user syncpt only
needs to expose the id and gpu address of the reserved syncpoint. None
of the rest (fences, priv cmdbufs) is needed for that, so it hasn't been
ideal to couple with the user-allocated syncpts.
With user syncpts now provided by channel_user_syncpt, remove the
user_managed flag from the kernel sync api.
This allows moving all the kernel submit sync code to be conditionally
compiled in only when needed, and separates the user sync functionality
in a more clear way from the rest with a minimal API.
[this is squashed with commit 5111caea601a (gpu: nvgpu: guard user
syncpt with nvhost config) from

This patch adds boundary value check for common.fifo parameters as
listed below.
1. nvgpu_channel_setup_bind() includes a condition to check that value
of num_gpfifo_entries does not exceed 2^31. Otherwise prints message and
returns error.
2. nvgpu_tsg_bind_channel() includes a condition to check if channel
subctx had ASYNC id. If true, runqueue selector is set to 1 and 0
otherwise. This check is to be moved from devctl to common.fifo.

Currently, in fifo unit, unit_assert() is redefined as assert with
common bail_out action. However, name assert() creates confusion with
