[Mpi-21] Change-Log entry is missing: Version number changed to 2.1

[Rolf Rabenseifner]

See
https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/mpi22/Change-log-2.1-versionnumber

I hope, that all implementers of MPI-2.1 detected this change
already without this Change-Log entry ;-)

Best regards
Rolf
