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.

This interface is an abstraction for sending messages between
processors with irq-context callbacks and no definition of
protocol.
We assume that for all IPC implementations, we can send over a
message identifier and a sized data payload, and that the receiving
side gets an interrupt on an incoming message. APIs exist to indicate
the max value of the message id and how much data can be sent over a
single message.
This will be a foundation to build various high-level drivers
which can be bound at runtime to this low-level interface. Some
examples:
* IPC where IPC messages are used as a doorbell to signal new data in
a shared queue
* IPC with various kinds of message buffering and deferred message
processing via semaphores
* IPC for serial console debug output, either a byte or a message at
a time
* IPC over UARTS in a non-shared memory environment where large-ish
messages are exchanged
* Shared memory IPC where data pointers are exchanged and a protocol
for freeing the data once the receiver is done with it
The size parameter passed to ipc_send() isn't propagated to the
receiving side. The receiver needs to infer how many bytes of
data to read in the callback function based on the protocol implemented
in the high-level driver; it can be based on message ID, or bits reserved
in the message ID for the message size, or some other mechanism.

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.

- Finally switched from ldw/stw to ldh/sth, as Benjamin noticed in an
earlier comment (I was using ARC ISA, and not ARC V2 ISA). So indeed
ldw/stw are obsolete and equivalent to ldh/std.
- clear, set and test were not working in case of using a memory address
which would not point to a register: bclr, bset and btst requires
registers as operands, and cannot deal with pure memory address (i.e.
something like [rx] is not valid), thus the requirement to load first
the value pointed by the address into a register, operate on that
register and storing the result of it into the pointed address.

This patch is based on some code contributed by Dirk Brandewie.
This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.
Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.
