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.

Tickless idle is not yet supported. We program the timer period
to the desired system clock tick rate (sys_clock_hw_cycles_per_tick).
This was renamed to the same name used in the Altera Embedded IP
Peripherals Guide; used by other CPUs than Nios II.

Basic build framework for Nios2. Everything is stubbed out,
we just want to have a build going so that we can start to
parallelize implementation tasks.
This patch is not intended to be functional, but should be
able to produce a binary for all the nanokernel-based
sanity checks.

The PIT is an unsupported device. On x86 based platforms, the LOAPIC_TIMER and
HPET_TIMER are the only supported timers.

All driver Makefiles are adding the same cflags and they
have been done inconsistenly, make all drivers inherit
from the top level Makefile and remove unused includes.

The name of the device is SYSTICK. The device name should be part of the
file name, like all other timer drivers we support. The name
'cortex_m_timer' said nothing about which device the driver is for, since
it's way too generic: it could be for any timer present on any Cortex-M
board.

Updates references to CONFIG_BSP_DIR to CONFIG_PLATFORM as part of the
BSP -> platform clean up.
Note that despite the renaming, the usage of the config option remains
unchanged.

According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build. This patch converts to them to the newer ccflags-y which also
fixes the problem.
