Rename __nvgpu_set_enabled() to nvgpu_set_enabled(). The original
double underscore was present to indicate that this function is a
function with potentially unintended side effects (enabling a feature
has wide ranging impact).
To not lose this documentation a comment was added to convey that this
function must be used with care.

The pd_cache header declarations were oriignally part of the
gmmu.h header. This is not good from a unit isolation perspective
so this patch moves all the pd_cache specifics over to a new
header file: <nvgpu/pd_cache.h>.
Also a couple of static inlines that were possible when the code
was part of gmmu.h were turned into real, first class functions.
This allowed the pd_cache.h header to not include the gmmu.h
header file.
Also fix an issue in the nvgpu_pd_write() function where the data
was being passed as a size_t for some reason. This has now been
changed to a u32.

This unit test covers the page_table map/unmap logic as well
as low level PDE/PTE handling.
This patch contains a first phase aiming to cover most
functionality and code coverage but it does not cover
most error handling cases nor formal requirements.

Add a unit test to cover the pd_cache unit. This unit is
responsible for maintaining the page directory allocations.
It's effectively a DMA slab allocator since we want to be
able to pack multiple sub page sized page directories into
a single page.

This adds the initial unit test for the fuse module and testing for
gp10b. It verifies the exposed APIs for this device in the fuse module.
To allow the hal_init to pass before the HAL for
read_gcplex_config_fuse() can be overridden, the default behavior of the
POSIX implementation for nvgpu_tegra_fuse_read_gcplex_config_fuse() is
changed.
This provides 100% code and branch coverage for this unit/device.

We will need to organize the unit tests in order to keep the
units/ directory managable.
The basic idea here is to mirror the common/ structure in
nvgpu proper under units/. There's one additrion at the
moment though: posix. This is for posix environment related
tests.
Also added a fix for the runlist unit test. Add it to the
tmake sources and move the nvgpu-runlist/ directory to just
runlist/.

This unit test covers the nvgpu allocator high level logic for
calling nvgpu allocator imlementation routines. The nvgpu_allocator
code is generally very simple.
This gets to >90% coverage of the module. Once the fault injection
code is merged the failure path after nvgpu_mutex_init() will also
be coverable.

This will make it easier to stage the make build of userspace nvgpu
through module branching. Otherwise we will have a nightmare of
integration with almost certain dev-kernel lockdowns.
As functions get unit tested they should be added to the exports
file.

Add support for compiling nvgpu in a POSIX compliant userspace.
This code adds all of the necessary abstraction interfaces (mostly
stubbed) to enabled extremely limited and basic functionality in
nvgpu.
The goal of this code is to facilitate unit testing of the nvgpu
common core. By doing this in userspace it is much easier to write
tests that rely on very particular states within nvgpu since a user
can very precisely control the state of nvgpu.
