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.
Fixes CID 714119: Dereference before NULL check
Wrong value checked in conditional.

- 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.

unfortunately not possible.

pkg{data,lib,includedir}, use our own ompi{data,lib,includedir}, which is
always set to {datadir,libdir,includedir}/openmpi. This will keep us from
having help files in prefix/share/open-rte when building without Open MPI,
but in prefix/share/openmpi when building with Open MPI.

Features:
- Support for an override parameter file (openmpi-mca-param-override.conf).
Variable values in this file can not be overridden by any file or environment
value.
- Support for boolean, unsigned, and unsigned long long variables.
- Support for true/false values.
- Support for enumerations on integer variables.
- Support for MPIT scope, verbosity, and binding.
- Support for command line source.
- Support for setting variable source via the environment using
OMPI_MCA_SOURCE_<var name>=source (either command or file:filename)
- Cleaner API.
- Support for variable groups (equivalent to MPIT categories).
Notes:
- Variables must be created with a backing store (char **, int *, or bool *)
that must live at least as long as the variable.
- Creating a variable with the MCA_BASE_VAR_FLAG_SETTABLE enables the use of
mca_base_var_set_value() to change the value.
- String values are duplicated when the variable is registered. It is up to
the caller to free the original value if necessary. The new value will be
freed by the mca_base_var system and must not be freed by the user.
- Variables with constant scope may not be settable.
- Variable groups (and all associated variables) are deregistered when the
component is closed or the component repository item is freed. This
prevents a segmentation fault from accessing a variable after its component
is unloaded.
- After some discussion we decided we should remove the automatic registration
of component priority variables. Few component actually made use of this
feature.
- The enumerator interface was updated to be general enough to handle
future uses of the interface.
- The code to generate ompi_info output has been moved into the MCA variable
system. See mca_base_var_dump().

This commit also modifies the rmaps framework. The following variables were
moved from ppr and lama: rmaps_base_pernode, rmaps_base_n_pernode,
rmaps_base_n_persocket. Both lama and ppr create synonyms for these variables.
