[Mpi-22] MPI_BOOL

[Jeff Squyres]

Back in the mid-90's, there was no "bool" C type.  But since C99,  
there has been.  So we should have an MPI_BOOL type.

The point was made to me today, however, that the C "bool" type and  
the C++ "bool" type may not be compatible -- so MPI_BOOL and MPI::BOOL  
may actually represent different things.

(I don't propose a solution :-) -- I just bring up the topic to be  
considered for 2.2...)
