added by hwloc's embedding so that it doesn't appear in
libhwloc_embedded.la (and therefore propogate all the way up to
libmpi.la).
Committed upstream in hwloc SVN r5588.

This is not in response to any known bug, but rather just a
pre-emptive, defensive move to help prevent bugs in code that forgets
to initialize a field.

Other changes:
- Added a flag to the MCA variable system to indicate a variable should go away
when its group does. Both mca_base_framework_var_register() and
mca_base_component_var_register() set this flag.
Notes:
- mca_base_components_open is deprecated. It will be removed in a future commit.
- All frameworks should use MCA_BASE_FRAMEWORK_DECLARE to declare their
framework structure.
- All calls to framework open/close functions should be changed to use the
mca_base_framework_* functions.
- Instead of special-casing installdirs a flag was added to prevent calling
into the variable system when opening a framework.
- Ralph: Clarify the functional definition of the "register" function in the
MCA framework object - it had the same name as another function that does a
totally different thing.
- As per discussion with Ralph the behavior of mca_base_framework_register()
is to always call mca_base_framework_components_register() if the framework's
register function was successful. This removed the need for frameworks to
have to call this function directly.

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.

the upstream 1.5 series, and was therefore missed when we brought
1.5.2 to OMPI.

library to multiple libraries that are implicitly sucked into the executable
as a dependency of libmpi. The initialize hook isn't visible to libc on some
linux distributions when it's in libopal and libopal isn't explicity linked
into the executable. The fix is to have a duplicate initialize hook in
libmpi as well as libopal. *sigh*.
