This moves the processing packets of upper layers from RX thread to the
system workqueue so they have the same priority as the TX callbacks
which has the added benefit of making any protocol on top of L2CAP to
be executed using system wq stack.

The struct json_obj_descr definition allocates only 2 bits for type
alignment. Instead of using them literally minus 1 to encode 1, 2, or 4,
let's store the alignment's shift value instead so that 1, 2, 4 or 8 can
be encoded with the same 2 bits to accommodate 64-bit builds.

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.

The fifo/lifo API is implemented on top of the queue API with macros
that blindly force a cast to struct k_queue. Providing a reference to
the _queue member from the k_fifo structure is much cleaner as it let
the compiler perform pointer type checking. Generated code is identical.

We had architectures doing this differently, some had a dedicated

specific sys_io implementation into a sys_io file and include it
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.

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.

It's useful to be able to inspect the key returned from

commands. Dedicated buffer is used to story all command lineary.
History capacity is in bytes not in number of entries, e.g.
