Kumar Gala bf53ebf2c8 arch: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  There are few places we dont convert over to the new
types because of compatiability with ext/HALs or for ease of transition
at this point.  Fixup a few of the PRI formatters so we build with newlib.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Anas Nashif c1347b4730 kernel: replace all remaining nanokernel occurances
replace include <nanokernel.h> with <kernel.h> everywhere and also fix
any remaining mentions of nanokernel.

Keep the legacy samples/tests as is.

Benjamin Walsh f6ca7de09c kernel/arch: consolidate tTCS and TNANO definitions
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.

Andrew Boie 17c0b372a2 x86: improve exception APIs
Previously, exception stubs had to be declared in assembly
language files. Now we have two new APIs to regsiter exception
handlers at C toplevel:

 _EXCEPTION_CONNECT_CODE(handler, vector)
 _EXCEPTION_CONNECT_NOCODE(handler, vector)

For x86 exceptions that do and do not push error codes onto
the stack respectively.

In addition, it's now no longer necessary to #define around
exception registration. We now use .gnu.linkonce magic such that
the first _EXCEPTION_CONNECT_*() that the linker finds is used
for the specified vector. Applications are free to install their
own exception handlers which will take precedence over default
handlers such as installed by arch/x86/core/fatal.c

Some Makefiles have been adjusted so that the default exception
handlers in arch/x86/core/fatal.c are linked last. The code has
been tested that the right order of precedence is taken for
exceptions overridden in the floating point, gdb debug, or
application code. The asm SYS_NANO_CPU_EXC_CONNECT API has been
removed; it was ill- conceived as it only worked for exceptions
that didn't push error codes. All the asm NANO_CPU_EXC_CONNECT_*
APIs are gone as well in favor of the new _EXCEPTION_CONNNECT_*()
APIs.

CONFIG_EXCEPTION_DEBUG no longer needs to be disabled for test
cases that define their own exception handlers.

Benjamin Walsh f703f7d0f6 debug: add target GDB server
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.
