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.

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.

ompio has historically changed the WRONLY flag provided by the applicaiton
to RDWR to allow for the data sieving optimization within the two-phase I/O
fcoll component. This change did not have a performance impact
on regular UNIX file systems, but seems to hurt performance on NFS (and maybe Lustre?)
So provide an option that allows to keep the WRONLY option, and raise an error
if tha fcoll/two-phase would actually like to use the data sieving.

* 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.

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.

Fix CID 72296: Resource leak (RESOURCE_LEAK):
Changed code to goto exit instead of returning to ensure memory is
freed.
Fix CID 712589: Out-of-bounds read (OVERRUN):
In this loop i and j are identical and always less than
iov_count. The CID was triggered because i was incremented if i was <
iov_count. This meant that if the loop did go on the next iteration
would access an invalid index.
Fix CID 741363: Uninitialized scalar variable (UNINIT):
Allocate tmp_len with calloc to insure every index is initialized.
Fix CID 741364: Uninitialized pointer read (UNINIT):
Allocate recv_types with calloc to ensure all indices are always
initialized. Also added a check to not loop and destroy if recv_types
is NULL.
Also added a NULL check on the allocation of decoded iov. This is not
the cause of CID 126784 but should be fixed.
Fix CID 712588: Out-of-bounds read (OVERRUN):
Similar to CID 712589. Should silence the issue.

Fixes CIDs 72300, 72344, 1196764-1196768, 72300: Resource leaks
Mulitple allocated arrays are going out of scope at the end of
mca_fcoll_two_phase_file_write_all. Free these arrays. Also removed
the extraneous NULL checks since free (NULL) is safe in C.
Change returns to goto exit where the allocated resources are freed.
Fixes CIDs 72285-72292, 72297, 72298: Resource leaks
Change all appropriate return statements to goto exit to ensure that
all resources are freed. Also removed the NULL checks since free
(NULL) is safe in C.
Fixes CIDs 72295, 72296: Resource leaks
Moved free of requests and recv_types to after exit label. This will
ensure these are freed on error.
Also added a loop and statement to free send_buf which is going out of
scope at the end of the function.
Fixes CIDs 72336-72240, 735197, 735198: Resource leaks
Moved the exit label before to before the resources are released and
changed all appropriate return statements to goto exit. Also removed
extraneous NULL checks because free (NULL) is safe in C.
Fixes CIDs 72341, 72343, 1196805-1196809: Resource leaks
Free all resources after exit label and change return statements to
goto exit to ensure all resources are freed on error.
Fixes CID 1269973: Unused value
Check return code of ompi_request_wait_all. If it fails jump to the
exit.

- 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.
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

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.
