Rewrites the timestamping logic to always generate timestamps
via a function pointer that is initialized to sys_cycle_get_32(),
but can be changed to point to a user-supplied function. This
eliminates the need for an if/then/else construct in every place
that a timestamp is generated.

Prepares the kernel event logger APIs for inclusion in the

* Gets rid of obsolete thread monitor code.
* Renames "timer_func" global variable to "_sys_k_timer_func"
to align it with kernel naming conventions.

There was no check to see if the head of a list was empty before trying
to fetch the next node in the list. The fix is added to
sys_dlist_peek_next() so that it also return NULL if the node parameter
is NULL, in addition to being the tail of the list.
Since the value is not used until the second iteration of the loop, and
there will be no second iteration if the list is empty, as long as the
CPU does allow reading at address 0, this was not causing any issues.
Our ARC targets did not seem to like that.
Fixes ZEP-1263 and ZEP-1297.

There was a lot of duplication between architectures for the definition
of threads and the "nanokernel" guts. These have been consolidated.
Now, a common file kernel/unified/include/kernel_structs.h holds the
common definitions. Architectures provide two files to complement it:
kernel_arch_data.h and kernel_arch_func.h. The first one contains at
least the struct _thread_arch and struct _kernel_arch data structures,
as well as the struct _callee_saved and struct _caller_saved register
layouts. The second file contains anything that needs what is provided
by the common stuff in kernel_structs.h. Those two files are only meant
to be included in kernel_structs.h in very specific locations.
The thread data structure has been separated into three major parts:
common struct _thread_base and struct k_thread, and arch-specific struct
_thread_arch. The first and third ones are included in the second.
The struct s_NANO data structure has been split into two: common struct
_kernel and arch-specific struct _kernel_arch. The latter is included in
the former.
Offsets files have also changed: nano_offsets.h has been renamed
kernel_offsets.h and is still included by the arch-specific offsets.c.
Also, since the thread and kernel data structures are now made of
sub-structures, offsets have to be added to make up the full offset.
Some of these additions have been consolidated in shorter symbols,
available from kernel/unified/include/offsets_short.h, which includes an
arch-specific offsets_arch_short.h. Most of the code include
offsets_short.h now instead of offsets.h.

Defines an object tracing list for each kernel object type
that supports object tracing, and ensures that both statically
and dynamically defined objects are added to the appropriate list.
Ensure that each static kernel object is grouped together with
the other static objects of the same type. Revise the initialization
function for each kernel type (or create it, if needed) so that
each static object is added to the object tracing list for its
associated type.
Note 1: Threads are handled a bit differently than other kernel
object types. A statically-defined thread is added to the thread
list when the thread is started, not when the kernel initializes.
Also, a thread is removed from the thread list when the thread
terminates or aborts, unlike other types of kernel objects which
are never removed from an object tracing list. (Such support would
require the creation of APIs to "uninitialize" the kernel object.)
Note 2: The list head variables for all kernel object types
are now explicitly defined. However, the list head variable for
the ring buffer type continues to be implicitly defined for the
time being, since it isn't considered to be an core kernel object
type.

By default, kernel event logger is using the system timer. But on
some platforms where the timer driver maintains the system timer
cycle accumulator in software, such as ones using the LOAPIC timer,
the system timer behavior leads to timestamp errors. For example,
the timer interrupt is logged with a wrong timestamp since the HW
timer value has been reset (periodic mode) but accumulated value not
updated yet (done later in the ISR).
This patch is adding the possibility to register a timer callback
function that will be used by the kernel event logger. For example,
on Quark SE, this allows using RTC or AON counter which accuracy is
sufficient and behavior more straight forward compared to system
timer.

The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).
It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.
