The inline versions are renamed to remove the _inline suffix, and the
non-inline versions are removed from the code base.

Benjamin Walsh 6469e578cb irq: do not use _inline versions of irq_lock/unlock
Standardize on using the irq_lock/irq_unlock (non-inline) symbols
everywhere.

The non-inline versions provide absolutely no benefits, so they will be
removed in a subsequent commit, and the inline versions will have their
_inline suffix removed.

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.

Peter Mitsis 4fe98a46f5 Initialize stack area in _NewContext()
Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext().  This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

Peter Mitsis 40b5200c73 Optimizations to _NewContext() and _NewContextInternal()
Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.

Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.
