This commit fixes several vagrind errors. Included:
- installdirs did not correctly reinitialize all pointers to NULL
at close. This causes valgrind errors on a subsequent call to
opal_init_tool.
- several opal strings were leaked by opal_deregister_params which
was setting them to NULL instead of letting them be freed by the
MCA variable system.
- move opal_net_init to AFTER the variable system is initialized and
opal's MCA variables have been registered. opal_net_init uses a
variable registered by opal_register_params!
- do not leak ompi_mpi_main_thread when it is allocated by
MPI_T_init_thread.
- do not overwrite ompi_mpi_main_thread if it is already set (by
MPI_T_init_thread).
- mca_base_var: read_files was overwritting mca_base_var_file_list
even if it was non-NULL.
- mca_base_var: set all file global variables to initial states on
finalize.
- btl/vader: decrement enumerator reference count to ensure that it
is freed.

There were a number of bugs in the framework/variable code that
affected deregistration:
- Frameworks could be erroneously closed if seperately registered and
opened then subsequently closed. This was a bug in the original
design which only reference counted opens but not
registrations. This would cause undefined behavior if
MPI_T_finalize actually calls ompi_info_close_components as
intended. Now both registrations and opens are reference counted
and frameworks/components are not torn down until the matching
number of close calls have been made.
- group_find_by_name did not pass the invalidok flags down
to mca_base_var_group_get_internal correctly.
- Group deregistration caused the group to be completely reset. This
does not match the behavior required by MPI_T as it could reduce
the number of variables/subgroups in a group.
This commit also updates MPI_T_finalize to call
ompi_info_close_components as originally intended.
Closes#374
