b0461f8d3c the back pointer from the ompio_file structure to the ompi_file_t structure 
has to be set earlier in case the user disables the lazy_open option.

072b18e197 Code cleanup for the time breakdown feature in ompio/fcoll 
- make the internal structure follow the Open MPI naming convention
 - provide a single flag/macro which controls the compilation/utilization of this
   feature, to avoid that somebody using this has to modify every single
   fcoll component. A configure option could be added later if desired.

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.

db5af26de7 Performance tuning. make sure we catch if the user wants to set the default fileview and replace it with our optimized default file view. Otherwise, performance will suffer. file_get_view should still return the correct filetype, not our optimized default file view. This is the correct version compared to ffa67b96933acafb3cfacf39a074d3dc1fe134ae, which unfortunately broke 
some test cases in mpi_test_suite. Thanks for @ggouaillardet for reporting this!

824d488709 - make the split collective shared file pointer operations work 
- minor code restructering in io/ompio required for that.

e380f8c235 - fix the delete priority of the ompio component 
- some application use MPI_File_delete as a collective function (e.g. IOR), which I think is not really covered by the standard. Right now, one process succeeds and theother ones return an error code. Fix that by not returning no error if the file that we try to delete does not exist anymore, to make these applications work.

bf89131f9e add owner files to opa/ompi/orte mca directories 
This commit adds an owner file in each of the component directories
for each framework.  This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page.  Currently there are two
"fields" in the file, an owner and a status.  A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.

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.
