Unit test to target the interface.bsearch unit. The goal here is to
provide line coverage for the unit. Considering that the underlying
implementation is using POSIX's bsearch, there is no need to verify
the behavior of bsearch in depth.

Introduce nvgpu_bitmap_set() and nvgpu_bitmap_clear() APIs to wrap the
bitmap_set() and bitmap_clear() APIs, respectively. The new nvgpu_*
versions accept unsigned length parameters since length is logically an
unsigned value where bitmap_set and bitmap_clear accept signed values.
We inherit bitmap_set and bitmap_clear from the OS, so we can't
directly change those.
Also, change uses of the old APIs to the new ones.
These changes resolve MISRA Rule 10.3 violations for implicit assignment
of objects of different essential or narrower type.

invalid values due to integer promotions. So, for sanity, we should

This reverts commit ade1d50cbe.
Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.
Use an array of pointers to runlists in fifo_gk20a. The array
keeps existing indexing by runlist_id. In this patch a context
is still allocated for each possible runlist, but follow up
patch will allow to skip context allocation for inactive
runlists.

Move bus related HAL code to new top level HAL directory: hal/.
This directory should mirror the common directory as much as
possible.
There's some nice pros here:
1. Isolate HAL and common code.
2. Since the common directory should not be including HAL
related headers directly this structure will make it
easier to catch these sorts of bugs with a script.

Drop the "runlist_" part in the runlist section of the HAL ops. For
example:
- old: g->ops.runlist.runlist_wait_pending
- new: g->ops.runlist.wait_pending
At the same time, drop the "fifo_" part from the function names. For
example:
- old: gk20a_fifo_runlist_wait_pending
- new: gk20a_runlist_wait_pending
Also rename eng_runlist_base_size to count_max. The size of the
eng_runlist_base register array depicts the maximum possible number of
runlists in the chip for which count_max is more descriptive.

There should not be any compilation issues with POSIX build if we
include nvlink.c to it.
2. Rename the nvlink file in POSIX build to avoid the tmake
duplicate filename issue.
3. Set CONFIG_TEGRA_NVLINK for POSIX to enable reporting of MISRA
violations in nvlink code by the MISRA scanner.
4. To fix the build issues:
a. Add stubs in POSIX
b. Return the 'err' variable set during dev_shutdown() as 'err'
