ztest was not working with unified kernel and v1 APIs and not many tests are
using ztest right now, so instead of making it work with old APIs, convert it
to unified kernel completely so that new tests written using ztest would be
unified kenrel based.

Provides users with a more compact and intuitive API for kernel
timers.
Provides legacy support for microkernel timers and nanokernel
timers by building on the new kernel timer infrastructure.
Each timer type requires only a small amount of additional
wrapper code, as well as the addition of a single pointer
field to the underlying timer structure, all of which will be
easily removed when support for the legacy APIs is discontinued.

Revises the test to account for changes in LIFO object behavior
in the unified kernel.
Note: A LIFO object shouldn't really be used to try and pass
data items between two different threads in an ordered manner,
as this test is doing. Ordered behavior should only be expected
when a single thread is adding and removing items from a LIFO.
A LIFO is typically used to pass data items between different
threads when ordering doesn't matter -- for example, when using the
LIFO to implement a shared pool of data items that can be allocated
and returned by a bunch of threads. (A LIFO object is more efficient
than a FIFO object for implementing this kind of pool.)

Fixes bug with the private definition of the helper task
that incorrectly added task to the EXE task group.
(This is problematic because the regression task also
starts the helper task!)
Revises test code to use legacy kernel types for task id and
task priority values, rather than using "int", since these
types are not necessarily integer values in the unified kernel.
Revises task/thread priorities used by test so they fit within
the unified kernel's default priority range.

Binutils ld has an annoying misfeature (apparently a regression from a
few years ago) that alignment directives (and alignment specifiers on
symbols) apply only to the runtime addresses and not, apparently, to
the load address region specified with the "AT>" syntax. The net
result is that by default the LMA output ends up too small for the
addresses generated in RAM. See here for some details:
https://sourceware.org/ml/binutils/2013-06/msg00246.htmlhttps://sourceware.org/ml/binutils/2014-01/msg00350.html
The required workaround/fix is that AFAICT any section which can have
inherit a separate VMA vs. LMA from a previous section must specify an
"ALIGN_WITH_INPUT" attribute. Otherwise the sections will get out of
sync and the XIP data will be wrong at runtime.
No, I don't know why this isn't the default behavior.
A further complexity is that this feature only works as advertised
when the section is declared with the "AT> region" syntax after the
block and not "AT(address)" in the header. If you use the header
syntax (with or without ALIGN_WITH_INPUT), ld appears to DOUBLE-apply
padding and the LMA ends up to big. This is almost certainly a
binutils bug, but it's trivial to work around (and the working syntax
is actually cleaner) so we adjust the usage here.
Note finally that this patch includes an effective reversion of commit
d82e9dd9 ("x86: HACK force alignment for _k_task_list section"), which
was an earlier workaround for what seems to be the same issue.

This test is prompted by incorrect multilib selection for Cortex-M4
(armv7e-m subarchitecture) in Zephyr SDK 0.8.1 toolchain. The idea
is do an operation which guaranteedly results in a call to a support
routine in libgcc, which is part of multilib set. Long long division
is used as such, with a fault produced (see README) when built for
BOARD=frdm_k64f.
This test now passed with SDK 0.8.2 for frdm_k64f, but is added in
the hope of preventing/easing diagnosis of future regressions.

- Use a more limited range of priorities, since the current
implementation of the unified kernel only works with 32 priorities
total. Instead of starting at 10 and going up by 5 up to 50, start
at 5 and go up by 1 up to 12.
- The definition of kmutex_t has changed from a uint32_t to a struct
k_mutex *, causing this to not work anymore:
const kmutex_t private_mutex;
since this makes the object constant instead of the reference to it.
Private object must be referenced like this instead:
kmutex_t const private_mutex;
since const is left-associative.
