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.

Gets rid of single-line comments required by a previous set of
coding conventions. These comments provide no value to readers
and just clutter things up.

Revises kernel so that it uses the standard NULL symbol defined
for C99, rather than having its own custom symbol.

Revises kernel so that it uses the standard boolean type library
defined for C99, rather than having its own custom boolean type.
Also revises sample projects that used the non-standard type.

There are many scenarios where it is convenient to have a helper to
evaluate the number of elements in an array. Having this helper in a
common place helps avoid duplicated code.

Add endian conversion functions needed for network protocols.
Currently Bluetooth needs sys_le16_to_cpu and sys_cpu_to_le16
to implement endian safe stack. Note that the OS is not guaranteed
to be endian safe generally.
