We are interested in supporting some XIP x86 platforms which are
unable to fetch CPU instructions from system RAM. This requires
refactoring our dynamic IRQ/exc code which currently synthesizes
assembly language instructions to create IRQ stubs on-the-fly.
Instead, a new approach is taken. Given that the configuration at
build time specifies the number of required stubs, use this
to generate a build time a set of tiny stub functions which simply
push a 'stub id' and then call common dynamic interrupt code.
The handler function and handler argument is saved in a table keyed by
this stub id.
CONFIG_EOI_HANDLER_SUPPORTED removed, the code hasn't been conditionally
compiled for some time and in all cases we call _loapic_eoi() when
finished with an interrupt.
Some other out-of-date verbiage in comments related to supporting
non-APIC removed.
Previously, when dynamic exceptions were created a pointer would
be passed in by the caller reserving ram for the stub code. Since
this is no longer feasible, two new Kconfig options have been added.
CONFIG_NUM_DYNAMIC_EXC_STUBS and CONFIG_NUM_DYNAMIC_EXC_NO_ERR_STUBS
control how many stubs are created for exceptions that push
an error code, and no error code, respectively.
SW Interrupts are no longer triggered by "int <vector>" hard-coded
assembly instructions. Instead this is done by sending a self-directed
inter-processor interrupt from the LOAPIC, using a new API
loapic_int_vect_trigger(). In this way we get rid of dynamically
generated code in irq_test_common.h.
All interrupts call _loapic_eoi() when finished, since this is now
the right thing to do for all IRQs, including SW interrupts.
_irq_handler_set() for x86 no longer requires the old function pointer
to be supplied.

Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.
All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM. This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.
This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.

This introduces a generic driver set for console messages routed over
inter-processor interrupt (IPI) channels. These drivers bind to a
low-level IPI driver instance for the actual transport of messages.
ipi_console_sender installs printk and/or stdout hooks to forward
messages over IPI. There is currently no buffering on the sending side.
ipi_console_receiver installs an IPI callback which stashes incoming
characters into a ring buffer, which is monitored by a nanokernel
fiber. The fiber buffers the characters on a per-line basis and sends
them to either printk or stdout. Multiple instances of this driver
may be created in case you need to receive console data from multiple
CPUs.

With this, the UART console has its own initialization which is not
dependent on UART init routines.
This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.
Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.
Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.
Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.
