Show an example of using the btl_usnic_connectivity_map option. Also,
mention that another reason for the "total connectivity failure" may
be due to asymmetric / unexpected routing.

The contrib/check-help-strings.pl gets confused if the topic is an
inline logic check, so separate it into two calls to show_help.

The _strdup usage in opal/util/basename looks like it was a product of
Windows compatibility (see r11336), which we don't care about any
more. Further, opal/win32/win_compat.h, which we sitll maintain for
cygwin compatibility, #define's strdup to _strdup (which is what
Microsoft wants you to use).
So this old _strdup in opal/util/basename.c (and its corresponding
check in configure.ac) should just be removed.

_strdup is not part of any include file i could find on Solaris 10.
manually add the _strdup prototype if needed.

This commit was SVN r32449.
In core library portions of the configury (e.g., top-level
configure.ac itself), we were calling AC_CHECK_LIB and
OPAL_CHECK_FUNC_LIB to check for various libraries.
'''SIDENOTE:''' It turns out that modern Autoconf has AC_SEARCH_LIBS,
which does just about exactly what OPAL_CHECK_FUNC_LIB does. So this
commit effectively replaces OPAL_CHECK_FUNC_LIB with AC_SEARCH_LIBS.
However, we never bothered to add these found libraries to the wrapper
compiler list of libraries used for static linking (doh!). We've been
getting lucky for quite a while that components were adding the same
libraries to their wrapper compiler LIBS list.
This is problematic, however, if we don't build some of these
components. For example, Paul Hargrove noticed that if he configured
with --disable-shared --enable-static --disable-io-romio, ROMIO was no
longer adding some libraries to the wrapper LIBS list -- libraries
that just happened to also be needed by core OPAL/ORTE/OMPI layers.
The solution is not to use AC_CHECK_LIB or OPAL_CHECK_FUNC_LIB, but
use a pair of new macros:
* OPAL_SEARCH_LIBS_CORE: a wrapper around AC_SEARCH_LIBS. If we add
something to $LIBS, then also add it to the wrapper list of static
libraries. This is the main piece of functionality that was
wrong/missing.
* OPAL_SEARCH_LIBS_COMPONENT: similar to OPAL_SEARCH_LIBS_CORE, but
instead of directly adding it to the wrapper list of static
libaries, add it to <framework>_<component>_LIBS (which eventually
gets slurped up into the wrapper list of static libraries. See the
lengthy comment in config/opal_setup_wrappers.m4 near the beginning
of OPAL_SETUP_WRAPPER_INIT() for a more detailed explanation).
Most components did this correctly already, but one or two weren't
right, so I implemented this second macro quite similar to the
first and put it everywhere we already used AC_SEARCH_LIBS or
OPAL_CHECK_FUNC_LIB.
This needs to soak for a day or two on the trunk before moving to the
v1.8 branch.

Ensure that the connectivity checker agent only uses pointers from the
client that is the same process as the agent.
Not necessary for the v1.8 branch -- this is a trunk/v1.9-only problem.
This commit was SVN r32438.
Make the del_procs, module finalize, and endpoint destructors be the
same between trunk and v1.8, with one exception: the very beginning of
v1.8 module_finalize calls del_procs for each proc to simulate/pretend
the trunk/v1.9 PML behavior of calling del_procs before module_finalize.
This commit was SVN r32437.
Fixes an assertion failure in --enable-debug builds and SEGVs in normal
builds.
I'm not 100% sure I like this model, but it at least seems to be
consistent. Some variation on this scheme will need to be adapted to
the trunk, where usnic_del_procs() is called by the PML instead of
internally in usnic_finalize().
A related bug (but with different mechanics) is #4832.

Previously, the connectivity agent was pretty dumb: it took whatever
pings it got and ACKed them. Then we added an agent check to ensured
that the ping actually came from the source interface that it said it
came from. Now we add another check such that when a ping is received
on interface X that corresponds to usnic module Y, we ensure that the
source interface of the ping is on the all_endpoints list for module Y
(i.e., module Y expects to be able to talk to that peer interface).
This detects cases where peers have come to different conclusions
about which interfaces should be used to communicate (which is bad!).
This usually reflects a network misconfiguration.
Fixes CSCuq05389.
