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.

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!

ed02927767 - do not set the contiguous memory option in the collective operations. It 
should not be stored on the file handle anyway, since it is not a property of
the file.

5fae72b9aa Add the MPI 2.2 MPI_Dist_graph functionality. 
This patch reshape the way we deal with topologies completely. Where
our topologies were mainly storage components (they were not capable
of creating the new communicator), the new version is built around a
[possibly] common representation (in mca/topo/topo.h), but the functions
to attach and retrieve the topological information are specific to each
component. As a result the ompi_create_cart and ompi_create_graph functions
become useless and have been removed.

In addition to adding the internal infrastructure to manage the topology
information, it updates the MPI interface, and the debuggers support and
provides all Fortran interfaces.

9eeb3b5d50 # 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. 
# The queues are initialized in file-open
