two minor updates:
- in all components: use the fh->f_bytes_per_agg value
(which might have been set by an info object) instead
of re-reading the mca parameter
- vulcan and dynamic_gen2: replace one allgather operation
by an allreduce, since it is used to determine the sum
of an array.

and some internal structure elements/components. Along the way,
add support for the cb_nodes Info object.

for very large offsets, ome ariables used in the fcoll/dynamic_gen2
code base were under certain circumstances not large enough to hold
intermediate values. This issue was more detected in the vulcan component
but could happen in the dynamic_gen2 component as well.

keep track of the sizeof the blocklen_per_process and displs_per_process
on the aggregator datastructure to minimze the number of realloc function
calls required in the shuffle_init operation.

instead of using a temporary buffer and copy data into the temp buffer before sending, use a derived datatype to describe the data that needs to be sent during a cycle in the collective I/O operation.

ompio has the unique problem, that mca parameters set in the io/ompio component
have to be accessible from other frameworks as well. This is mostly done to avoid
a replication in the parameter names and to reduce the number of mca parameters that
and end-user has to worry about.
This commit introduces a generic function to retrieve ompio mca parameters, the function pointer
is stored on the file handle. It replaces two functions that used the same concept already for
one parameter each.

* Resolves#3705
* Components should link against the project level library to better
support `dlopen` with `RTLD_LOCAL`.
* Extend the `mca_FRAMEWORK_COMPONENT_la_LIBADD` in the `Makefile.am`
with the appropriate project level library:
```
MCA components in ompi/
$(top_builddir)/ompi/lib@OMPI_LIBMPI_NAME@.la
MCA components in orte/
$(top_builddir)/orte/lib@ORTE_LIB_PREFIX@open-rte.la
MCA components in opal/
$(top_builddir)/opal/lib@OPAL_LIB_PREFIX@open-pal.la
MCA components in oshmem/
$(top_builddir)/oshmem/liboshmem.la"
```
Note: The changes in this commit were automated by the script in
the commit that proceeds it with the `libadd_mca_comp_update.py`
script. Some components were not included in this change because
they are statically built only.

Passed the below set of symbols into a script that added ompi_ to them all.
Note that if processing a symbol named "foo" the script turns
foo into ompi_foo
but doesn't turn
foobar into ompi_foobar
But beyond that the script is blind to C syntax, so it hits strings and
comments etc as well as vars/functions.

since Open MPI now requires a C99, and ptrdiff_t type is part of C99,
there is no more need for the abstract OPAL_PTRDIFF_TYPE type.

As we changed the ABI (forcing a major release), we can limit
the size of the predefined communicators by moving the collective
structure outside the communicator. This might have a minimal,
but unnoticeable, impact on performance. This approach has been
discussed during the January 2017 devel meeting.

This fixes a bug reported in-house occuring with this component. It is triggered if the data assigned to different aggregators is highly differing, leading to different number of internal iterations required to handle it.

- move the sort_iovec operations to fcoll/base
- move set_view_internal to common/ompio
- move set_file_default to common/ompio
- remove io_ompio_sort, not used anymore.
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.
