Andrew Boie 2a1ae3f436 ARM: ARC: put sw_isr_table in ROM by default
We can save a great deal of RAM this way, it only needs to be
in RAM if dynamic interrupts are in use.

At some point this config option broke, probably when static
interrupts were introduced into the system.

To induce build (instead of runtime) errors when irq_connect_dynamic()
is used without putting the table in RAM, the dynamic interrupt
functions are now conditionally compiled.

Andrew Boie 583126adf9 microkernel: remove task_irq_free() API
This is being removed for a few reasons:

- AFAICT this is the only API in Zephyr that follows an allocate/free
model.

- There are no public APIs in the interrupt subsystem for releasing
or reconfiguring an interrupt. This code was relying on arch-specific
private APIs. If we really want to keep this capability we should
make these APIs public and consistent across arches.

- The use-case for this API is not clear, as Zephyr is not intended
for hot-pluggable peripherals. Built-in hardware tends to need its
interrupt for its entire life cycle.

- The current implementation of dynamic interrupts on x86 does not
support freeing a dynamic IRQ that was reserved with
irq_connect_dynamic(), causing this code not to work. To add this
would require reimplementing _get_dynamic_stub() to use a bitfield
or set of bitfields to track unused stubs rather than the simple
counter it uses now.

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

Peter Mitsis d63a4f7bf7 nano_timers: Simplify nano_xxx_timer_test() API family
Simplifies the nanokernel timer API so that the timeout parameter must be
specified when invoking nano_isr_timer_test(), nano_fiber_timer_test(),
nano_task_timer_test() and nano_timer_test().

This obsoletes the following APIs:
	nano_fiber_timer_wait()
	nano_task_timer_wait()
	nano_timer_wait()

Note that even the though the new API requires that the timeout parameter
be specified, there are currentl only two acceptable values:
	TICKS_NONE and TICKS_UNLIMITED

Theoretically, the current implementation would allow one to supply a
finite positive value for the timeout and the system would wait up to
that many ticks for the timer to expire. However, it is thought that
that unnecessarily complicates the nanokernel timer model and so it is
left as an unsupported option.  Should that change, then that feature
could be enabled by updating the documentation.
