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().
opal: update core and components to mca_base_var system
orte: update core and components to mca_base_var system
ompi: update core and components to mca_base_var system
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.

to make MPI_IN_PLACE (and other sentinel Fortran constants) work on OS
X, we need to use the following compiler (linker) flag:
-Wl,-commons,use_dylibs
So if we're compiling on OS X, test to see if that flag works with the
compiler. If so, add it to the wrapper FFLAGS and FCFLAGS (note that
per a future update, we'll only have one Fortran compiler anyway).

Okay, cleanup the prior commit so that the default component search path shows in ompi_info, and remains available in component_find.

- add a cmake module for searching libltdl libraries and headers
- a configure option to enable DSO build, default OFF.
- update a few source files for including correct header

finally brings in functionality that is already on the 1.2 branch, and
was developed and tested in the v1.2ofed branch (and other places).
Short version of new features:
* Support for ibv_fork_init()
* Automatically fill in the openib BTL bandwidth value by
querying the HCA port
* Installdirs functionality
* Fixes to always use -I in the Fortran wrapper compilers (#924)
* Gleb's mpool updates
* Remove some kruft in btl/openib/configure.m4, therefore
fixing the harmless warnings noted in #665
* Bunches of updates to the Linux RPM spec file
I.e., effectively the same thing that r14411 brought to the v1.2
branch.
Also effectively brought in r14432 and r14433 (some fixes on top of
the original r14411 commit to v1.2). Still need to bring in the moral
equivalent of r14445 after this commit (fixes to installdirs).

range of OS friendly path management functions, such as opal_basename
opal_dirname. They should always be used instead of basename and
dirname. There are several functions which allow us to create paths
that are compatible with the OS.
The OPAL_ENV_SEP define should be used (instead of ':') when a env
variable is splitted.

installation directories) in configure, the files that depend on this
information are not properly rebuilt. If you need this information,
don't setup a -D in the Makefile.am - instead, include
opal/install_dirs.h.
* Use the : option in AC_CONFIG_FILES to avoid needing to expose that
we are playing around with temporary files with our headers to avoid
rebuilding
* Clean up the version file information a bit, and like the install
directory stuff, make sure that there is a dependency so that
ompi_info gets rebuilt properly when a version number changes.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

r8698), with changes below:
- Split wrapper flags into those required for each of the three projects,
and cleaned up some cruft (including the LIBMPI_EXTRA_*FLAGS) through-
out the build system
- Added opal_init_util and opal_finalize_util to allow init / cleanup
of all the opal code that doesn't require the MCA system
- Create standalone key=value file parser, based on the one that used
to be in the mca param parser, so that it can be shared in multiple
places
- Add wrapper datafiles for opal, orte, and ompi wrappers, and add
wrapper compiler with support for all the old features

instance of opal_output_stream_t
- Still need to re-enable output files

add a -I to find the included ltdl.h (vs. a system-installed ltdl.h)
- Clean up kruft in a bunch of Makefile.am's to remove now-unnecessary
AM_CPPFLAGS settings to get static-components.h for each framework
- Move the component_repository API functions out of opal/mca/base/base.h
and into opal/mca/base/mca_base_component_repository.h in order to
decrease unnecessary dependencies (e.g., before this, almost
everything in the tree depended on ltdl.h, which is unnecessary --
only a small number of files really need ltdl.h)

ompi/).
- There's still a handful of places that have orte/ #include files;
still need to clean those up
- A lot of places still use ompi/include/constants.h -- those need to
be converted over to use OPAL_ return codes and then switch to the
opal constants.h. This commit is the first few steps towards
that...
This commit was SVN r6843.
- new preferred API calls for registering MCA parameters are
mca_base_param_reg_{int|string} and
mca_base_param_reg_{int|string}_name.
- See opal/mca/base/mca_base_param.h for docs on new calls.
- Can now register and lookup a value at the same time.
- Can now mark a parameter "read only" at registration time
- Can now mark a parameter "internal" at registration time
- Can now associate a help message with the parameter at registration
time; displayed in the ompi_info output.
The old API calls are still available for backwards compatibility
(mca_base_param_register_{int|string}. They will eventually be
removed -- all developers are encouraged to use the new APIs from here
on out and replace any old calls with the new API.
Some params were also renamed -- the previous convention of using
"base_" as a prefix for any param that was not associated with a
component is henceforth deprecated. Instead, use one of the following
prefixes:
mca: for anything in the MCA base itself
opal: for anything in OPAL
orte: for anything in ORTE
mpi: for anything in OMPI

* Add ability to completely disable libltdl (the dlopen code to load
dynamic shared objects) to configure: --disable-dlopen
* Added MCA param (component_disable_dlopen) to disable DSO loading
at runtime
* Made the event library behave in some not-completely-erroneous way
on platforms where it has absolutely no eventops support (ie, no
select, poll, or epoll)
* Disabled orte_wait, opal_few, and opal_daemon_init code on
platforms without fork, waitpid support. All non-init functions
will return OPMI_ERR_NOT_SUPPORTED
* Disable orteprobe tool when fork or pipe aren't supported
