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.
NOTE: CONFIG_NANO_TIMEOUTS must be enabled.

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.

Revises and documents the confusing and inconsistent set of
dependencies for the kernel's two main public include files.
The files now now clearly exhibit the following behaviors:
1) microkernel.h provides access to all public microkernel APIs,
public nanokernel APIs (both architecture-independent and
architecture-specific ones), and public "generic kernel" APIs
(such as kernel version and system clock APIs).
2) nanokernel.h provides access to all public nanokernel APIs
(both architecture-independent and architecture-specific ones),
and public "generic kernel" APIs.

Routines are no longer flagged as constructors using the FUNC_CONSTRUCT(level)
macro. This is because some compilers do not support constructor levels.
To indicate that a routine should be a constructor, the SYS_PREKERNEL_INIT()
macro should be used AFTER the definition of the routine. For example ...
void my_library_init(void)
{
...
}
SYS_PREKERNEL_INIT(my_library_init, 500);
The first parameter to SYS_PREKERNEL_INIT() is the name of the routine. The
second is the priority level (000...999). The lower the number, the higher
the priority. NOTE: It is important that all three digits are specified;
otherwise the linker may put the constructors in an undesired order.
