195ec89732 fcoll/base: mv coll_array functionis to fcoll base 
the coll_array functions are truly only used by the fcoll modules, so move
them to fcoll/base. There is currently one exception to that rule (number of aggreagtors
logic), but that function will be moved in a long term also to fcoll/base.

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.

b90c83840f Refactor the request completion (#1422) 
* Remodel the request.
Added the wait sync primitive and integrate it into the PML and MTL
infrastructure. The multi-threaded requests are now significantly
less heavy and less noisy (only the threads associated with completed
requests are signaled).

* Fix the condition to release the request.

f167be1c91 ompio: always return valid info from FILE_GET_INFO 
MPI-3.1 says that even if no info keys are set on the file, we need to
return a new, empty info.

Thanks to Lisandro Dalcin for identifying the issue.

Fixes open-mpi/ompi#1630

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.

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!

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.
