Peter Mitsis 9fce2a2209 Remove obsolete ctors section
Remove prototype support for C++ constructors, since it is not well
designed. Device drivers (or other application code) that requires an
automatic initialization capability should use the device initialization
macros instead.

Note: Support for C++ constructors may be re-introduced at a later date.
However, a number of issues need to be settled, such as when the
constructors are invoked and what context they run in. (Running them
during nanokernel initialization, as was previously done, is probably
not the right approach.)

Andrew Boie f18f102feb nanokernel: add optional ring buffer data type
This patch is based on some code contributed by Dirk Brandewie.

This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.

Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.

Allan Stephens 63fae40f7d Eliminate nanokernel's nanometrics.c
File contents moved to the nanokernel initialization file, since
they don't warrant their own distinct source file.

Benjamin Walsh 617f9c5b4c nanokernel: allow nano time tracking to be used in microkernels
The nanokernel time tracking code (ticker) can now exist in microkernel
systems. This allows the ticker that drives nano timers and timeouts to
advance the tick count for these in a microkernel, thus allow their
presence there. Previously, nano timers could not be used in a
microkernel.

Benjamin Walsh 87179c2e36 nanokernel: add NANO_TIMERS option
The nanokernel timers will be available in the microkernel, but can be
disabled if not needed. A kconfig option is needed for that: the option
is enabled by default, and only available in the nanokernel for now. It
will be made available in the microkernel in the future.

Anas Nashif bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.
