Simple tests to verify whether the microkernel timer system works
alongside the nanokernel timeouts and timers system.
Once the timer test is started, the nanokernel fifo timeout test is
started in parallel: each other's timeout times should not be affected
by the other. Also, a fiber is started, pending on a nanokernel timer,
and awakens in the middle of the microkernel timers expiring.

Test the nano_xxx_fifo_wait_timeout() APIs.
First, the task waits with a timeout and times out. Then it wait with a
timeout, but gets the data in time.
Then, multiple timeout tests are done for the fibers, to test the ordering
of queueing/dequeueing when timeout occurs, first on one fifo, then on
multiple fifos.
Finally, multiple fibers pend on one fifo, and they all get the
data in time, except the last one: this tests that the timeout is
recomputed correctly when timeouts are aborted.
NOTE: The timeout APIs test is contained within its own file so that it
is easily reusable by a microkernel test that verifies that nano
timeouts and microkernel timers can coexist.

The microkernel now announces the nanokernel ticks, and takes them into
account when computing the amount of time to stay in tickless idle.
This allows code linked against a microkernel to use the nanokernel
timers and timeouts.

The nanokernel time tracking code (ticker) can now exist in microkernel
systems. This allows the ticker that drives nano timers and timeouts to
advance the tick count for these in a microkernel, thus allow their
presence there. Previously, nano timers could not be used in a
microkernel.

The nanokernel timers will be available in the microkernel, but can be
disabled if not needed. A kconfig option is needed for that: the option
is enabled by default, and only available in the nanokernel for now. It
will be made available in the microkernel in the future.

Add the _timeout() variants to the _get_wait() routines. Those allow
waiting with a timeout. The return values are the same as for the
regular _get() routines: a valid pointer on success, NULL on failure.
Note that the task_ variant is still polling, and the task is not put on
a timeout queue, instead polling for the ticker change in addition to
data arriving on the LIFO.

It also adds an API allowing a fiber to sleep for a given amount of
ticks.

The timeout queue interface will allow having fiber interacting with the
nanokernel objects wait with a timeout. It can be completely excluded
from the kernel if not needed, via the CONFIG_NANO_TIMEOUTS option.
Most of the timeout queue interface is contained within timeout_q.h.
However, this file should never be included directly: rather, the
wait_q.h file is to be included instead, which itself provides NOOP
abstractions for some timeout functions when timeouts are not enabled in
the kernel.

The old doubly-linked list implementation had only support for very
basic operations, i.e. add at head and remove.
The new implementation is highly enhanced, allowing these operations:
- initialize list
- check if a node is the list's head
- check if a node is the list's tail
- check if the list is empty
- get a reference to the head item in the list
- get a reference to the next item in the list
- add node to tail of list
- add node to head of list
- insert node after a node
- insert node before a node
- insert node at position based on condition
- remove a specific node from a list
- get the first node in a list
The implementation is completely inline, since the operations are rather
simple and do not warrant a function call.
