Add a generic API for drivers to start workqueues and submit work
items. This is needed by drivers which need to schedule code that might
sleep from an ISR to run in fiber context.
Also add the option to start a system-wide workqueue.
Both additions are optional. They can be deactivated for systems that
do not need them.

We really should have more faith in the compiler, it generates
code to implement this exactly like the arch-specific assembly
versions, and on ARM is actually 4 bytes shorter.
FUNC_NO_FP used to disable the usual C preamble to update the
frame/stack pointers, which is how the sizes are still the same
or less. It's debatable how useful the occasional use of
FUNC_NO_FP is in practice since it hinders debugging and in a
production build frame pointers should be globally disabled, but
we can address that later.

The routines _int_latency_start() and _int_latency_stop() have been
replaced by macros that evaluate to nothing when the kernel config
option INT_LATENCY_BENCHMARK is not enabled thereby giving a performance
boost to the x86 versions of irq_lock() and and irq_unlock().

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.)

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.

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.

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.

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.
