Use of the old ompi_free_list_t and ompi_free_list_item_t is
deprecated. These classes will be removed in a future commit.
This commit updates the entire code base to use opal_free_list_t and
opal_free_list_item_t.
Notes:
OMPI_FREE_LIST_*_MT -> opal_free_list_* (uses opal_using_threads ())

Please verify your components have been updated correctly. Keep in
mind that in terms of threading:
OPAL_FREE_LIST_GET -> opal_free_list_get_st
OPAL_FREE_LIST_RETURN -> opal_free_list_return_st
I used the opal_using_threads() variant anytime it appeared multiple
threads could be operating on the free list. If this is not the case
update to _st. If multiple threads are always in use change to _mt.
Historically these two lists were different due to ompi_free_list_t
dependencies in ompi (mpool). Those dependencies have since been moved
to opal so it is safe to (finally) combine them. The combined free
list comes in three flavors:
- Single-threaded. Only to be used when it is guaranteed that no
concurrent access will be made to the free list. Single-threaded
functions are suffixed with _st.
- Mutli-threaded. To be used when the free list may be accessed by
multiple threads despite the setting of opal_using_threads.
Multi-threaded functins are suffixed with _mt.
- Conditionally multi-threaded. Common use case. These functions are
thread-safe if opal_using_threads is set to true.
Compatibility functions for the ompi_free_list_t and the old accessor
functions (OPAL_FREE_LIST_*) are available while the code base is
transitioned to the new class/functions.

Honestly, a bunch of this code could use similar treatment (i.e.,
AC_DEFUN a template that can be used for OPAL/ORTE/OMPI). However, I
don't quite have time for this today. Exercise left for the future reader...
This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
The RPATH support added a @{libdir} token into
<package>_WRAPPER_EXTRA_LDFLAGS. However, these flags are also
substituted into the pkg-config data files, and they don't understand
the @{foo} notation. So convert @{libdir} into ${libdir}, which
pkg-config *does* understand.
Thanks to Christoph Junghans (@junghans) for notifying us of the issue.
Fixes#406.
