General cleanup of RELEASE_NOTES.

Removed parts that are no longer relevant due to deprecated features
in MPICH or in the MPI standard.

### Large counts
* The new MPI-3 "large count" routines (e.g., MPI_Type_size_x) do not
work correctly due to 64-bit to 32-bit truncations occurring inside
the MPICH library. We expect to fix this in upcoming releases.
### Known runtime failures
* MPI_Alltoall might fail in some cases because of the newly added
fault-tolerance features. If you are seeing this error, try setting
the environment variable MPICH_ENABLE_COLL_FT_RET=0.
### Threads
### Fine-grained thread safety
* ch3:sock does not (and will not) support fine-grained threading.

* The MPD process manager can only handle relatively small amounts of
data on stdin and may also have problems if there is data on stdin
that is not consumed by the program.
* The SMPD process manager does not work reliably with threaded MPI
processes. MPI_Comm_spawn() does not currently work for >= 256
arguments with smpd.
### Performance issues

operations may erroneously fail. By explicitly completed, we mean
that the request associated with the operation is completed by one
of the MPI_Test or MPI_Wait routines.
### C++ Binding:
* The MPI datatypes corresponding to Fortran datatypes are not
available (e.g., no MPI::DOUBLE_PRECISION).
* MPI::ERRORS_RETURN may still throw exceptions in the event of an
error rather than silently returning.
