but it has worked fine everywhere that I've tried it.

[svn-r7687] Changed global completion count to use atomics rather than locks.  This will allow us to update the completion count asynchronously from other threads or interrupt contexts

Prevents duplicate storage on platforms like darwin that don't support
weak symbols and therefore have two libraries in order to support the
PMPI profiling interface.  Previously, there was also a copy in
libpmpich.a, which contains the actual "MPI_" versions of the routines.

In the old code it was possible that ROMIO freed the keyval multiple
times, rather than just once.  This was fine in MPICH2, which is robust
in the face of such behavior, but caused problems for ROMIO over Open
MPI.  We now utilize the MPI-2.2 LIFO ordering for attribute destruction
in order to free the keyval exactly once.

1. Move UI specific parameters to a different structure, so other
components don't see them.

2. Rename HYD_handle to HYD_server_info to make the data in it
clearer.

3. Rename hydra.h to hydra_server.h (this is only used by the server
side). Also make sure the proxy side code does not include it.

4. Merge hydra_base.h and hydra_utils.h and make it hydra.h, as these
are the utility functions used for both the servers and the proxies.

1. Point out that C++, F77 and F90 support is optional and the users
can disable them.

2. Remove the recommendation for VPATH builds. While this is a
convenient option for system administrators or developers who maintain
multiple copies of MPICH2 builds, it is confusing for users.

3. Remove redundant description of configure options.

4. Remove the MPICH_INTERFACE_HOSTNAME environment variable from the
README, as in the default PM, we automatically pass it based on the
host list provided by the user.

5. Cleaned up several descriptions.
