On ARC, the _sw_isr_table has an actual size of CONFIG_NUM_IRQS - 16
because the 16 first IRQ are reserved.
This patch has no impact on the generated binary but allows the
debugger to display valid information instead of displaying 16 false
entries containing garbage.

Add sys_exc_connect() (and its x86-compatible alias nanoCpuExcConnect())
that allows connecting an exception handler at runtime.
The current implementation is a bit of a bastard, to avoid disturbing
the current implementation of the exception handlers. Instead of hooking
_exc_wrapper() in all vectors and adapting the exception handlers, the
current exception handlers are still hooked directly in the vectors.
When an exception is hooked at runtime, _exc_wrapper() gets installed in
the vector and the real handler gets inserted in _sw_exc_table; this
means that the scheme only works with non-XIP kernels.
This should be enhanced so that _exc_wrapper() is hooked in all vectors,
and that current exception handlers (for faults mostly) are reworked to
be inserted in the _sw_exc_table and wrapped in _exc_wrapper().

On ARM, GPRs are often known by two names. E.g. the stack pointer is
both 'sp' and 'r13', the first parameter to a function 'a1' and 'r0',
etc. This macro allows defining them in a data structure, e.g. in the
ESF, without having to create a union, use the correct type, etc: it is
less error-prone and makes for shorter code.

The image will be linked at a different address and with different
ROM/RAM sizes to allow running a bootloder image that loads a payload
image. The addresses/sizes depend on if it is a XIP image or not
(CONFIG_XIP), and in the case of a XIP image, if it is a bootloader
image (CONFIG_IS_BOOTLOADER) or not.
In the case of a bootloader, it is given the full ROM and
CONFIG_BOOTLOADER_SRAM_SIZE kB of SRAM. When not a XIP image, it is given
the full SRAM minus CONFIG_BOOTLOADER_SRAM_SIZE kB, and is linked at the
start of SRAM.

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.

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.

Update the advertising API according to what has recently been
discussed and agreed upon.
Naming-wise the most important change is the removal of "EIR" which
was confusing since this is mainly used with LE at the moment. The
Core Specification Supplement consistently uses the generic terms data
and data type to describe what we're dealing with here, so the new
names are bt_data and BT_DATA.
Another change is to detach the actual data from the struct by
converting it from an array to a pointer. This is not only essential
for supporting BR/EDR (which has a different length) but to also
minimize memory usage.
Another change is to require the caller of bt_le_adv_start() to
provide the array lengths of the ad and sd paramters. This way we
don't have to have the empty (8-byte) element at the end of each
array.
Lastly, the bt_le_adv_start() logic is slightly modified so that it
will always clear the respective data if necessary. Previously the
user might have been left with a previous callers data if it passed
NULL to the 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
