[boost] [Boost.Thread] mutex Win32 implementation changes

I've just checked in changes to Win32 implementations of the mutex and 
recursive_mutex classes. They now use a Win32 critical section instead 
of a mutex whenever possible for the normal and try_ variations, though 
not for the timed_ variations.

These are changes that were started on the mutex classes quite some time 
back on the thread_dev branch; I've finished the changes and applied 
them to the recursive_mutex classes as well.

In addition, the thread_dev branch has code that allows a mutex to be 
named, which allows it to be shared between two or more processes. This 
change was begun by Bill Kempf, but is only implemented for Win32. Any 
suggestions about the best way to add this feature to the pthreads and 
MPTasks implementations?
