Due to a quirk of the k20 UART, when checking if either a Tx or Rx
irq is ready, one must first check whether the UART has enabled the
Tx and/or Rx interrupts. If this is not done, then all one is doing
is testing the UART to determine if it is ready to Tx and/or Rx.

Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.
The change in API means that device drivers and sample
applications need to use the new API.
IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

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Some other out-of-date verbiage in comments related to supporting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.

Adds an input hook to be used by the interrupt handler uart_console_isr().
This hook permits the console input to detect a character escape sequence
that can be used to override the console's default input behavior.
This input hook can be set using the following API:
void uart_irq_input_hook_set(struct device *dev,
int (*hook)(struct device *, uint8_t));
The hook returns 1 if the handler should stop processing the character,
and 0 if it should not stop.

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

The reason why fifo_fill works in qemu but not on real hardware is
that qemu serializes all byte transmission 1 by 1. There is no
real hardware fifo emulated, and "fifo" depth is 1. On real
hardware, the controller owns an internal fifo, with a depth like
8 bytes on Quark x1000. And because of execution flow, how fast is
the controller etc etc... a fifo_fill call might fill in the
internal fifo of 8 bytes and then controller says "I am full"
(which means: "wait for the fifo to have space again"). That's
why poll_out() works: it does the same as fifo_fill and wait
that the internal fifo gets some space again before continuing.
And only when all bytes have been pushed in, it returns.
