K_THREAD_DEFINE() can no longer specify a thread group. However, it now
accepts a 'delay' parameter just as k_thread_spawn() does.
To create a statically defined thread that may belong to one or more thread
groups the new internal _MDEF_THREAD_DEFINE() macro is used. It is only used
for legacy purposes.
Threads can not both have a delayed start AND belong to a thread group.

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.

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.

Simplified some documentation, removing inconsistencies and making
it easier to understand by separating PM infrastructure areas and
soc specific components that implement the hooks.
Removed the DEVICE_SUSPEND_ONLY policy as it is redundant and
causes high complexity in the flow. It is also not practical
to use it because it was meant to be used without doing CPU or SOC
low power state operations. This means it would do device PM
operations in the ISR of the system timer used by the scheduler.
This can disrupt the scheduler time.
Added a check of a flag around the notification sent from the ISR
of the wake event and created APIs to set/clear it. This will
allow disabling the notification when not needed from
_sys_soc_suspend().
