  CogVM source as per VMMaker.oscog-eem.3113

Image file i/o. Check result of sqImageFile:Open: with invalidSqImageFile:,
instead of assming nill is the invalid value. This should address
opensmalltalk-vm Issue #607.

StackInterpreter:
Implement printing suspended processes in printAllStacks by searching the heap
for all processes (including subinstances) waiting on other than a linked list.
Hence nuke ClassMutex which specifies a slot in the specialObjectsArray which
has never been used in production.

CoInterpreterMT:
Override to printAllStacks also print the awol processes
