Allan Stephens 7da1dd860b Rename microkernel's kernel_struct.h to micro_private_types.h
The new name better reflects that this file contains private
microkernel APIs (types, structs, etc.) that are used by various
kernel subsystems.

Allan Stephens 570eabf9f8 Add k_ prefix to various microkernel source files
Adds the k_ prefix to files that don't have it. This emphasizes the
fact that the microkernel is the *real* Zephyr OS kernel, rather than
the nanokernel. Also, the k_ and _k_ prefixes are used for many private
microkernel APIs contained within these files, so using the k_ prefix
for these file names makes sense.

Dmitriy Korovkin 660878e4e2 irq_connect for x86 uses static stub array
In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.

Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.

Modify tests for unified interrupt register API

Tests that deal with interrupts are modified to work
with the new interrupt registration API.

Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects

Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.

Benjamin Walsh 1ae1ca0b39 microkernel: handle nanokernel ticks
The microkernel now announces the nanokernel ticks, and takes them into
account when computing the amount of time to stay in tickless idle.

This allows code linked against a microkernel to use the nanokernel
timers and timeouts.

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 bb660ae965 nanokernel: add timeout queue interface
The timeout queue interface will allow having fiber interacting with the
nanokernel objects wait with a timeout. It can be completely excluded
from the kernel if not needed, via the CONFIG_NANO_TIMEOUTS option.

Most of the timeout queue interface is contained within timeout_q.h.
However, this file should never be included directly: rather, the
wait_q.h file is to be included instead, which itself provides NOOP
abstractions for some timeout functions when timeouts are not enabled in
the kernel.

The size of the k_args strcture must be equivalent to ...
    CMD_PKT_SIZE_IN_WORDS * sizeof(uint32_t)

This is complicated by the fact that not only do different compilers treat the
size of 'bool' and 'enum' types differently, they may also pad structures
differently.  Both of these differences have direct impacts on the k_args
structure.  To work around this, the k_args fields 'alloc' and 'Comm' are
forcibly aligned to a 4-byte boundary, while the rest of the k_args structure
is packed.
