Initialization of semaphores was incorrect. It did not force
the count to "1" to indicate availability.
Interrupt support was added.
Problem where newlib's errno "overrides" that set by system calls
was addressed.
Fixed bug which resulted in all nodes using the same semaphore although
an array of semaphores was allocated.
