This commit removes a check that causes mca_base_group_register to
improperly create a new group instead of using an existing group
when the project and framework names are the same. This check was
originally intended to prevent forming groups with names like
ompi_ompi, opal_opal, etc but there is no reason why we shouldn't
allow that.

CID 1047278 Unchecked return value
Updated check for mca_base_var_generate_full_name4 to match other
checks. Logically equivalent to the old check. Not a bug.
CID 1196685 Dereference null return
Added check for NULL when looking up the original variable for a
synonym.
CID 1269705 Logically dead code
Removed code that set the project to NULL. Code was intended to be
removed with an earlier commit that added the project name into the
component structure. Added code to actually support searching for a
group with a wildcard ('*').
CID 1292739 Dereference null return
CID 1269819 Dereference null return
Removed unnecessary string duplication and strchr.
CID 1287030 Logically dead code
Refactored fixup_files code and confirmed that the code in question is
not reachable. Removed the dead code.
CID 1292740 Use of untrusted string
Use strdup to silence coverity warning.
CID 1294413 Free of address-of expression
Reset mitem to NULL after the OPAL_LIST_FOREACH loop to ensure we
never try to free the list sentinel.
CID 1294414 Unchecked return value
Use (void) to indicate we do not care about the return code in this
instance.
CID 1294415 Resource leak
On error free all the base pointer.

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

This commit adds an API for registering and querying performance
variables (mca_base_pvar) in the MCA base. The existing MCA variable
system API has been updated to reflect the new API: MCA variable
groups have performance variables, and new types have been added (double,
unsigned long long) to reflect what is required by the MPI_T
interface. Additionally, the MCA variable group code has been split
into its own set of files: mca_base_var_group.[ch].
Details of the new API can be found in doxygen comments in the header:
mca_base_pvar.h.
Other changes to the variable system:
- Use an opal_hash_table to speed up variable/group lookup.
- Clean up code associated with MCA variable types.
- Registered performance variables are printed by ompi_info -a. In the
future an option should be added to control this behavior.
Changes to OMPI:
- Added full support for the MPI_T performance variable interface.
