- the interrupt (both regular and fast) now does not do rescheduling
if the current thread is a coop thread or if the scheduler is not locked
- the _nanokernel.flags cache of _current.flags is not used anymore
(could be a source of bugs) and is not needed in the scheduling algo
- there is no 'task' field in the _nanokernel anymore: scheduling routines
call _get_next_ready_thread instead
- the _nanokernel.fiber field is replaced by a more sophisticated
ready_q, based on the microkernel's priority-bitmap-based one
- thread initialization initializes new fields in the tcs, and does not
initialize obsolete ones
- nano_private includes nano_internal.h from the unified directory
- The FIBER, TASK and PREEMPTIBLE flags do not exist anymore: the thread
priority drives the behaviour
- the tcs uses a dlist for queuing in both ready and wait queues instead
of a custom singly-linked list
- other new fields in the tcs include a schedule-lock count, a
back-pointer to init data (when the task is static) and a pointer to
swap data, needed when a thread pending on _Swap() must be passed more
then just one value (e.g. k_stack_pop() needs an error code and data)
- the 'fiber' and 'task' fields of _nanokernel are replaced with an O(1)
ready queue (taken from the microkernel)
- fiberRtnValueSet() is aliased to _set_thread_return_value since it
also operates on preempt threads now
- _set_thread_return_value_with_data() sets the swap_data field in
addition to a return value from _Swap()
- convenience aliases are created for shorter names:
- _current is defined as _nanokernel.current
- _ready_q is defined as _nanokernel.ready_q
- _Swap() sets the threads's return code to -EAGAIN before swapping out
to prevent timeouts to have to set it (solves hard issues in some
kernel objects).

This mechanism was intended to reserve space during the first pass for
certain data structures created by gen_idt, but this is unnecessary.
The only memory addresses that must be fixed between the two passes are the
locations of the interrupt stubs, which are in the .text section much
earlier than the generated data structures; they do not shift.

EM7D was recently merged, and one change suggested there was
to remove conditional checks for NSIM. It is OK to have the simulator
use the exact same memory addresses and sizes as would be found on the
board. This submission fixes EM9D and EM11D to be the same -- i.e.
to not have NSIM conditionals.

Since the unified kernel's build system doesn't properly handle
a file in the 'legacy' directory if it contains an initialization
function, some legacy code can't be located there. To avoid confusion,
the revised convention for legacy code is to keep any file that
contains only legacy code in the main kernel directory, and to give
it a "legacy_" prefix.

Ensures that all APIs which accept a timeout value wait for at least
the specified amount of time, and do not time out prematurely.
* The kernel now waits for the next system clock tick to occur before
the timeout interval is considered to have started. (That is, the only
way to ensure a delay of N tick intervals is to wait for N+1 ticks
to occur.)
* Gets rid of ticks -> milliseconds -> ticks conversion in task_sleep()
and fiber_sleep() legacy APIs, since this introduces rounding that
-- coupled with the previous change -- can alter the number of ticks
being requested during the sleep operation.
* Corrects work queue API that was incorrectly shown to use a delay
measured in ticks, rather than milliseconds.

For XIP images, in order to avoid the situation when
__data_rom_start is 32-bit aligned, but the actual data is placed
after rodata section, which may not end exactly at 32-bit border,
pad rodata section, so __data_rom_start points at data and it is
32-bit aligned.
On non-XIP images this may enlarge image size up to 3 bytes.
This is generally not an issue, since modern ROM and FLASH
memory is usually 4k aligned.
