nanokernel object timeouts.

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.

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.

This mega patch changes how Contiki uses buffers. In standard
Contiki there is only couple of static and global buffers.
This makes the stack non-reentrant and only usable in one
thread. This patch replaces the global buffer with buffer
supplied by caller (net_buf.h). The Contiki stack is still not
fully re-entrant after this (packet reassembly needs more TLC)
but it is a good start.

manner.

Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.
