+portals4 network module

+The portals4 netmod provides support for the Portals 4 network
+programming interface. To enable, configure with the following option:
+
+  --with-device=ch3:nemesis:portals4
+
+If the Portals 4 include files and libraries are not in the normal
+search paths, you can specify them with the following options:
+
+  --with-portals4-include= and --with-portals4-lib=
+
+... or the if lib/ and include/ are in the same directory, you can use
+the following option:
+
+  --with-portals4=
+
+If the Portals libraries are shared libraries, they need to be in the
+shared library search path. This can be done by adding the path to
+/etc/ld.so.conf, or by setting the LD_LIBRARY_PATH variable in your
+environment. It's also possible to set the shared library search path
+in the binary. If you're using gcc, you can do this by adding
+
+  LD_LIBRARY_PATH=/path/to/lib
+
+  (and)
+
+  LDFLAGS="-Wl,-rpath -Wl,/path/to/lib"
+
+... as arguments to configure.
+
+Currently, use of MPI_ANY_SOURCE and MPI dynamic processes are unsupported
+with the portals4 netmod.

    remove undeclared cvar check in portals4 netmod
    
    Fixes a compilation error when building the portals4 netmod. We
    considered implementing this cvar more generally at the nemesis level,
    but could not guarantee it is safe to disable this functionality
    in the other netmods.
