George Bosilca 697dc524c1 Deal with the ticket #1239 and #712. This will upgrade the Open MPI support
for the F90 type create functions to the requirements of MPI 2.1 standard.

Advice to implementors. An application may often repeat a call to
MPI_TYPE_CREATE_F90_xxxx with the same combination of (xxxx,p,r).
The application is not allowed to free the returned predefined, unnamed
datatype handles. To prevent the creation of a potentially huge amount of
handles, the MPI implementation should return the same datatype handle for
the same (REAL/COMPLEX/INTEGER,p,r) combination. Checking for the
combination (p,r) in the preceding call to MPI_TYPE_CREATE_F90_xxxx and
using a hash-table to find formerly generated handles should limit the
overhead of finding a previously generated datatype with same combination
of (xxxx,p,r). (End of advice to implementors.)

This commit fixes trac:1239, and #712.
