Two functions are proposed:
- sys_memcpy_swap(): will memcpy and swap the 2 given buffers
- sys_mem_swap(): will swap the buffer in place.
The idea is to propose 2 different functions optimized for 2 different
usage.

Reverts a change that was made to the defragmentation routine
when memory pool support was ported from the microkernel to the
unified kernel.
The change was intended to improve the readability of the algorithm,
but introduced a subtle change in behavior. For example, when
k and i are zero and the number of block set entries is one
the original algorithm did not execute the while loop, while the
revised algorithm executed the loop once.

Build breaks when enabling CONFIG_NEWLIB_LIBC because it has its own
sched.h file.
This is a bad symptom of a greater issue: the build system passes many
'-I<path>' options to the compiler, and that allows including header
files by simply specifying their names (when located somewhere else than
<zephyr>/include/) and can cause clashes when several files in different
locations have the same name, like in this case.
Fixes ZEP-1062.

Revises the test to account for changes in LIFO object behavior
in the unified kernel.
Note: A LIFO object shouldn't really be used to try and pass
data items between two different threads in an ordered manner,
as this test is doing. Ordered behavior should only be expected
when a single thread is adding and removing items from a LIFO.
A LIFO is typically used to pass data items between different
threads when ordering doesn't matter -- for example, when using the
LIFO to implement a shared pool of data items that can be allocated
and returned by a bunch of threads. (A LIFO object is more efficient
than a FIFO object for implementing this kind of pool.)

that incorrectly added task to the EXE task group.
(This is problematic because the regression task also
starts the helper task!)
Revises test code to use legacy kernel types for task id and
task priority values, rather than using "int", since these
types are not necessarily integer values in the unified kernel.
Revises task/thread priorities used by test so they fit within

When adding a thread to the ready queue, it is often known at that time
if the thread added will be the next one to run or not. So, instead of
simply updating the ready queues and the bitmask, also cache what that
thread is, so that when the scheduler is invoked, it can simply fetch it
from there. This is only done if there is a thread in the cache, since
the way the cache is updated is by comparing the priorities of the
thread being added and the cached thread.
When a thread is removed from the ready queue, if it is currently the
cached thread, it is also removed from the cache. The cache is not
updated at this time, since this would be a preemptive fetching that
could be overriden before the newly cached thread would even be
scheduled in.
Finally, when a thread is scheduled in, it now becomes the cached thread
since the fact that it is running means that by definition it was the
next one to run.
Doing this can speed up considerably some context switch times,
especially when a thread is preempted by an interrupt and the same
thread is scheduled when the interrupt exits.
