95c3e56961 gpu: nvgpu: unit: propagate fault injection to threads 
Change approach to how the fault injection state is stored to facilitate
propagating fault injection state to child-threads. Rather than each
unit maintaining a thread-local object, there is a thread-local
container stored in the posix-fault-injection itself. This container is
initialized for each test module so that is independent of other other
test modules (for parallel test module execution). When child threads
are created with nvgpu_create_thread(), the fault injection container is
configured for the child.

acc65f6e84 gpu: nvgpu: bug: move nvgpu_do_assert_print() into assert.c 
There was a header file circular dependency that was preventing
including some files. For example, for utils.h to include safe_ops.h
would include bug.h which included log.h which included bitops.h which
included utils.h. To break this loop, the macro nvgpu_do_assert_print()
into a function in a new file assert.c. With this change, log.h is no
longer required in bug.h.

This change also required adding a few includes in C files that were
picking up definitions through the chain above.
