Many tests used various incarnations of the mock register framework.
This was based on a dump of gv11b registers. Tests that greatly
benefitted from having generally sane register values all rely
heavily on this framework.
However, every test essentially did their own thing. This was not
efficient and has caused a some issues in cleaning up the device and
host code.
Therefore introduce a much leaner and simplified register framework.
All unit tests now automatically get a good subset of the gv11b
registers auto-populated. As part of this also populate the HAL with
a nvgpu_detect_chip() call. Many tests can now _probably_ have all
their HAL init (except dummy HAL stuff) deleted. But this does
require a few fixups here and there to set HALs to NULL where tests
expect HALs to be NULL by default.
Where necessary HALs are cleared with a memset to prevent unwanted
code from executing.
Overall, this imposes a far smaller burden on tests to initialize
their environments.
Something to consider for the future, though, is how to handle
supporting multiple chips in the unit test world.

Earlier, libnvgpu-drv.so and unit tests were being built with safety
debug profile unconditionally for all qnx and l4t builds.
In order to get coverage numbers corresponding to the release build
let us remove the overriding of the build profile for safety qnx
build. This also needs that these components are built only for
safety qnx and l4t builds.
For x86 and L4T userspace build, default profile is still set to
safety-debug.

Add macros for whitelisting coverity violations. These macros use pragma
directives. The pragma directives and whitelisting macros are only
enabled when a coverity scan is being run.
The whitelisting macros have been added to a new header called
static_analysis.h. The contents of safe_ops.h (CERT C safe ops) have
been moved into static_analysis.h because this will be the new header
for static analysis related macros/defines/etc.

Add the ability to override an apparently non-safe profile build
with the safe profile. This let's us force the safety profile build
in the userspace build (make under userspace/) and the tmake build
used for unit testing. Doing this keeps the tmake build closer to
the userspace which helps prevent regressions in the userspace
build as it has no direct GVS coverage.

Note that cflags are added to variable NVGPU_COMMON_CFLAGS that need

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.
