Basically, all driver file names should start with the driver type as
prefix: wdt_ in case of watchdogs here, and not something custom like
wdog_.
For clarity, wdog_ prefix could be changed to wdt_ in the source code
also but that's a detail and will not be addressed here.

The _k_mutex linker section is used to gather instances of
struct k_mutex into a list so that init_mutex_module() could iterate
that list to perform runtime initialization tasks. In this case, we're
not defining a struct k_mutex but rather a struct pthread_mutex which is
a completely different structure. Not only those struct pthread_mutex
would be corrupted with unexpected data, but since they're not the
same size as struct k_mutex, the actual struct k_mutex instances that
follow in the list would be misaligned and get corrupted too.
There is nothing that requires runtime initialization in the static
definition of a struct pthread_mutex so let's remove the section
attribute.

With code that looks like this:
for (int i = ARRAY_SIZfoo) - 1; i >= 0; i--) ...
If foo is empty, ARRAY_SIZfoo) will return 0. But since it is
implemented using an unsigned long, the answer to 0UL - 1 is
18446744073709551615 on a 64-bit system, and that doesn't fit into
an int. The compiler complains with:
warning: overflow in conversion from ‘long unsigned int’ to ‘int’ changes value from ‘18446744073709551615’ to ‘-1’ [-Woverflow]
Let's fix that and get the expected behavior simply by turning the
unsigned long into a signed long.

instead.
Move bits_portable.h to arch/common and split the file so more
architecture can reuse some of the definitions here instead of
duplicating code.
Where applicable use the common sys_io/ffs definitions.

ip register holds the stack_info.size (it is passed as argument
into z_arch_user_mode_enter(.)). We trust that the value of
stack_info.size contains the accurate size of the writable
stack buffer, above stack_info.start (as specified in kernel.h).
Therefore, we do not need to subtract any bytes for the MPU
stack guard. This allows us to clean-up one more occurrence of
CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT in userspace.S.

The internal "reschedule" API has always understood the idea that it
might run in a ISR context where it can't swap. But it has always
been happy to swap away when in thread mode, even when the environment
contains an outer lock that would NOT be expecting to swap! As it
happened, the way irq locks are implemented (they store flag state
that can be restored without context) this would "work" even though it
was completely breaking the synchronization promise made by the outer
lock.
But now, with spinlocks, the error gets detected (albeit in a clumsy
way) in debug builds. The unexpected swap triggers SPIN_VALIDATE
failures in later threads (this gets reported as a "recursive" lock,
but what actually happened is that another thread got to run before
the lock was released and tried to grab the same lock).
Fix this so that swap can only be called in a situation where the irq
lock key it was passed would have the effect of unmasking interrupts.
Note that this is a real behavioral change that affects when swaps
occur: it's not impossible that there is code out there that actually
relies on this "lock breaking reschedule" for correct behavior. But
our previous implementation was irredeemably broken and I don't know
how to address that.

Architectures that lack implementations of synchronous traps (via
Z_ARCH_EXCEPT()) end up using a z_except_reason() implementation that
doesn't actually trap at all. It just invokes
z_NanoFatalErrorHandler() in the current thread context.
That has two problems:
First, it was just blindly assuming that the error handling invoked
would abort the current thread, swap away, and never return. But that
can be application code in z_SysFatalErrorHandler that we can't
control.
Second, it was too broad with this assumption and stuff a
CODE_UNREACHABLE hint in for the compiler. But in fact
z_except_reason() may be invoked in interrupt context (for example the
stackprot check) where it may NOT swap away and WILL return
synchronously from the call. This doesn't seem to have caused a
miscompilation in production code, but it made a total voodoo hash out
of my debugging around this macro for an hour or so until I figured
out why my logging was being optimized out.
Do the abort unconditionally instead of relying on the app, and remove
the incorrect compiler hint.

Contrary to the comment in code, this test is NOT, in fact, compiled
with a traditional ticked kernel. Spinning won't work reliably
because interrupts won't necessarily be delivered when you expect.
This test case would fail spuriously as I moved things around when
debugging.
Doing it right (using a k_timer in this case) is actually less code
anyway.

The z_reschedule() call (as of the accompanying fix) will not swap
away from a thread if called with a nested irq lock held.
But for the specific case of aborting the current thread, we
absolutely need to swap regardless of how many locks the thread that
just aborted might have held. So call z_swap() explicitly here.
This preserves the existing z_reschedule() call in other circumstances
for compatibility with existing test cases, but adds a note explaining
why it's there when the only obvious reason for it is already covered.
