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()

The microkernel server now relies on the fact that the command packets,
events, and semaphores passed to it via its command stack are 32 bit
aligned. This change explicitly ensures this alignment, rather than
leaving it to the compiler's discretion.

Revises microkernel semaphore sub-system to allow ISRs and fibers
to give a semaphore without having to define a command packet set.
The microkernel server now supports a 3rd command type on its
command stack, allowing a semaphore to be given in a similar manner
to the one used for the existing "give event" command type.

Revises microkernel server command stack processing to allow the
server to support more than 2 types of commands. The lowest 2 bits
of the command now indicate the command's type:
0 - process specified command packet
1 - give specified event (from ISR or fiber)
2 - give specified semaphore (from ISR or fiber)
3 - reserved for future use
Note: Support for type 2 will be provided in a future commit.

This patch enables defining microkernel events within source code.
This is similar to other private kernel object patches.
The test has been modified a little bit due to the fact that
the event ID is now a memory address, instead of numeric ID.

Introduces the SYS_DEFINE_DEVICE() macro, which supports 5 distinct
levels of device initialization and 100 priorities within each level.
Note: The existing init macros (e.g. nano_early_init()) have been
adapted to utilize the enhanced initialization model, but will
eventually be retired.

Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.
Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

Revises microkernel initialization code by incorporating the existing
_k_kernel_init() and main() routines into _main(). This optimizes kernel
initialization a bit, and allows application code to use main()
if desired -- for example, as the entry point to an application task.
The change also eliminates the need for sysgen to generate a routine
whose content is always the same.
This change preserves the existing order of operations done during
kernel initialization, and leaves further improvements for later.

Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.

statically, i.e. what has to be done dynamically.
