The nanokernel timers and timeouts won't be dependent on each other, so
the expiry handling code needs to be able to only contain the necessary
code depending on what is enabled in the kernel.

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.

The nanokernel needs access to these values since the nanokernel objects
API will provide a way of waiting with timeouts.

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.

This new API allows starting a fiber with a delay. It returns a handle
to allow cancelling it before the fiber starts, via the cancel API.
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.
