Owen Anderson 68f6598c69 Insert a SmartMutex templated class into the class hierarchy, which takes a template parameter specifying whether this mutex 
should become a no-op when not running in multithreaded mode.  Make sys::Mutex a typedef of SmartMutex<false>, to preserve source compatibility.

Reid Spencer f404981bf2 For PR540: 
Add a Mutex class for thread synchronization in a platform-independent way.
The current implementation only supports pthreads. Win32 use of Critical
Sections will be added later. The design permits other threading models to
be used if (and only if) pthreads is not available.
