environment variables corresopnding to framework MCA parameters so
that the opal MCA base loads '''all''' components (not just the ones
specified in the environment variables). This has the side-effect of
not showing the user's value when displaying the framework MCA
parameters via --param output. For example:
{{{
shell% setenv OMPI_MCA_btl foo
shell% ompi_info --param btl base
}}}
The above sequence would show a "<none>" value for the "btl" parameter
instead of "foo".
This commit restores the environment after we munge it to make the
loader load all components. Hence, the above command sequence will
show "foo" for the "btl" parameter value, not "<none>".
This commit was SVN r14771.
