os/atomic.h --> include/sys/atomic.h
WARNING: There are almost certainly some bugs introduced here, but I
believe that using this system will get us to a stable and portable
library faster in the long run.
Other changes:
threads/mutex
Reorganized to use pthreads or asm atomic operations as available.
Untested Windows implementation added using InterlockedExchange() funcion.
threads/thread
Added an untested Windows implementation
other places
Updates to include the "right" header files or to use
ompi_atomic_add_int() rather that fetchNadd() etc.
