The definition of MPI_T_pvar_get_index was incorrect. This commit
fixes the definition and adds a missing return code.

If a performance variable session has no handles we should be returning MPI_SUCCESS
for MPI_T_pvar_start, MPI_T_pvar_stop, and MPI_T_pvar_reset. The code was returning
an unitialized value. This commit also updates the error code to return the proper
error on failure.

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.

mca_base_var_get now can return OPAL_ERR_NOT_FOUND if a variable no
longer exists. This commit updates the return code check to ensure
the correct MPI_T error code is returned to the user.

This commit was SVN r32161.
Several fixes:
- I was allowing an MPI_T_cvar_handle to be created for an invalid
variable. Fixed this by checking if the variable is valid in
mca_base_var_get.
- Use a better error code when the caller tries to create an unbound
pvar handle for a bound variable.
- Return the verbosity level in MPI_T_cvar_get_info.

Also, since I put some of the macros for these silent/verbose rules up
in the top-level Makefile.man-page-rules file, I renamed it to
Makefile.ompi-rules.
I've had this sitting around for a while; now seems like as good a
time as any to commit it.

See https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/377
This ticket adds the following functions to the standard:
- MPI_T_cvar_get_index, MPI_T_pvar_get_index, and MPI_T_category_get_index
The ticket has passed and the functions are part of MPI-3.1 that will
be released sometime later this year. In Open MPI the functions expose
existing internal functionality so they are low-risk to add to 1.8.0. I
will leave it up to Ralph whether he wants to accept these into 1.8.

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.

Fixes:
- Segmentation fault when using watermark variables.
- Segmentation fault when using a handle bound to a no longer valid
performance variable.
- Incorrect return codes from MPI_T_pvar_* functions.
