This avoids the case where the system has multiple threads using
floating point and the threads were not properly configured to use
floating point. The misconfigured threads will only take the fault on
first use of a floating point instruction.

Andrew Boie 2a1e4266e8 IPI console driver with test case
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.

Andrew Boie f18f102feb nanokernel: add optional ring buffer data type
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.

Benjamin Walsh 0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

Benjamin Walsh c1f9fd888d irq: make utility functions private
irq_handler_set, irq_priority_set and irq_disconnect have been made
private by prepending an underscore to their names:

	irq_handler_set -> irq_handler_set
	irq_priority_set -> irq_priority_set
	irq_disconnect -> irq_disconnect

The prototypes have been removed from header files when possible, and
extern statements used in C code where they were called.

_irq_priority_set() for ARM is still in the header file because
IRQ_CONFIG() relies on it.

Then, multiple timeout tests are done for the fibers, to test the ordering
of queueing/dequeueing when timeout occurs, first on one fifo, then on
multiple fifos.

Finally, multiple fibers pend on one fifo, and they all get the
data in time, except the last one: this tests that the timeout is
recomputed correctly when timeouts are aborted.

NOTE: The timeout APIs test is contained within its own file so that it
is easily reusable by a microkernel test that verifies that nano
timeouts and microkernel timers can coexist.

Benjamin Walsh 5b6017e059 test_lifo: test timeout APIs
Test the nano_xxx_lifo_wait_timeout() APIs.

First, the task waits with a timeout and times out. Then it wait with a
timeout, but gets the data in time.

Then, multiple timeout tests are done for the fibers, to test the ordering
of queueing/dequeueing when timeout occurs, first on one lifo, then on
multiple lifos.

Finally, multiple fibers pend on one lifo, and they all get the
data in time, except the last one: this tests that the timeout is
recomputed correctly when timeouts are aborted.
