50cec456fb ompi_request_complete with signal 
Rewrite the ompi_request_complete function to take in account the
with_signal argument. Change the comment to explain the expected
behavior.
Alter all the ompi_request_complete uses to make sure the status of the
request is set before calling ompi_request_complete.

0aa3049bfc Performance tuning: change the default behavior of ompio to *not* segment individual read/write operations. 
In most cases, performance seems to be better if not segmented.

dc05b709a7 it is ok to not have a sharedfp component selected, as long as no 
sharedfp functionality is being used. Return an error however if no
sharedfp component is selected and the applications calls a
file_read/write_shared function.

0f59ce6591 use the fbtl return value as originally intended, namely to retrieve the 
number of bytes written and read. Status contains now the actual number of
bytes written for individual operations. For collective operations, this is
unfortunately not possible.
