Symbols now use the K_ prefix which is now standard for the
unified kernel. Legacy support for these symbols is retained
to allow existing applications to build successfully.

as essential to system operation.

including the system workqueue.

Semaphore groups are not supported by the unified kernel (other than
via the legacy APIs).
A select() or poll() type mechanism may be introduced in the future
to provide a more general capability for a thread to wait on multiple
kernel objects simultaneously.

Adds thread option information. Corrects and enhances information
about the thread's stack area and the spawning of threads.

Fifo section now mentions the existence of this capability, and
notes the associated APIs. (Including an example of using the APIs
is not done, since the amount of code needed to show the creation
of the list of data items is significant, and is likely of little
interest to most users.)

Event is such an overloaded and generic term (event logger, *kernel*
event logger, "protocol" events in other subsystems, etc.), that it is
confusing for the name an object. Events are kinda like signals, but not
exactly, so we chose not to name them 'signals' to prevent further
confusion. "Alerts" felt like a good fit, since they are used to "alert"
an application that something of significance should be addressed and
because an "alert handler" can be proactively registered with an alert.

- replace instances of 'task' and 'fiber' with 'coop' and 'preempt'
thread
- remove reference to task monitor and task transition logging, since
this is a concept that is irrelevent in the unified kernel.

Ring buffer section now resides under "other" topic, since the
ring buffer type is a general purpose type (like the singly and
doubly linked list types), rather than a kernel-specific type.
Enhances ring buffer section to improve content and improve
consistency with the form used elsewhere in the Kernel Primer.
Also corrects a minor error in the ring buffer API documentation.

Revises documentation for the kernel clocks to align it
with the actual behavior of the unified kernel.
Revises documentation for the kernel timer object type
to provide users with a more compact and intuitive API
that supports (directly or indirectly) the capabilities
of the now defunct microkernel timer and nanokernel
timer object types.
Note: A separate commit will be used to implement the
revised timer API described here.
