A non-tickless system with 10ms granularity was occasionally
taking up to 70ms for the cancellation to be propagated back.

Currently, a queue/fifo getter chooses how long to wait for an
element. But there are scenarios when putter would know better,
there should be a way to expire getter's timeout to make it run
again. k_queue_cancel_wait() and k_fifo_cancel_wait() functions
do just that. They cause corresponding *_get() functions to return
with NULL value, as if timeout expired on getter's side (even
K_FOREVER).
This can be used to signal out of band conditions from putter to
getter, e.g. end of processing, error, configuration change, etc.
A specific event would be communicated to getter by other means
(e.g. using existing shared context structures).
Without this call, achieving the same effect would require e.g.
calling k_fifo_put() with a pointer to a special sentinal memory
structure - such structure would need to be allocated somewhere
and somehow, and getter would need to recognize it from a normal
data item. Having cancel_wait() functions offers an elegant
alternative. From this perspective, these calls can be seen as
an equivalent to e.g. k_fifo_put(fifo, NULL), except that such
call won't work in practice.

ztest has a number of assert style macros and used a baseline assert()
that varies from the system definition of assert() so lets rename
everything as zassert to be clear.

This option is added in order to support Xtensa, which needs more stack than
other architecture. This allows having a centralized way to change stack
requirements for all tests.
This extra stack size is eaqual to 0 for most architectures, except Xtensa
which requires additional 768 bytes for each stack.
