Allan Stephens 073442ecc5 kernel: Treat aborting by main() as a fatal system error
An application-supplied main() routine is now considered to be
essential to system operation. Thus, if main() experiences an
error that aborts the main thread a fatal system error is raised.

Note: If main() completes its work and does a standard return-
to-caller the main thread terminates normally.

Allan Stephens f48f263665 kernel: Rename USE_FP and USE_SSE symbols
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.

Allan Stephens e3e0b29418 unified/doc: Remove semaphore groups documentation from Kernel Primer
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.

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.)

Benjamin Walsh 31a3f6a70e unified: rename 'events' to 'alerts'
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.

- remove reference to task monitor and task transition logging, since
  this is a concept that is irrelevent in the unified kernel.

Allan Stephens 11a1bb4125 unified/doc: Update ring buffers section of Kernel Primer
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.

Allan Stephens bf684a10ba unified/doc: Update timing section of Kernel Primer
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.
