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.

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 ffa67b9693, which unfortunately broke

# Extracting timing information for individual components of collective algorithm using a generic queue.

# This is triggered based on a mca-paramater and can be used with all collective modules.
# Individual queues maintained for read and write.
# The additional communication to combine data is done at file-close so that the
actual timing of collective-operations will not get affected.
