Errata against ns-3.29 release

The following issues have been identified since the ns-3.29 release, and will be addressed in a future ns-3.29.1 release update.

MacOs Clang 10 compatibility: Shortly after the ns-3.29 release, a MacOs Clang compiler update was issued; this causes the ns-3 build to fail as follows:

   ./ns3/make-event.h:665:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
   typedef void (*F)(U1, U2, U3);
                  ^
   ./ns3/make-event.h:699:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
   typedef void (*F)(U1, U2, U3, U4);
                  ^
   ./ns3/make-event.h:633:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
   typedef void (*F)(U1, U2);
                  ^
   ./ns3/make-event.h:665:20: error: unused typedef 'F' [-Werror,-Wunused-local-typedef]
   typedef void (*F)(U1, U2, U3);
                  ^
   4 errors generated.

This can be worked around by passing the '--disable-werror' flag to Waf configuration step; e.g.:

   ./waf configure --disable-werror --enable-examples --enable-tests

API scan for ns-allinone-3.29: The version of pybindgen associated with ns-allinone-3.29 is incorrect, and the bindings toolchain will not install correctly. An example error output is:

       from pybindgen.castxmlparser import ModuleParser, PygenClassifier, PygenSection, WrapperWarning, find_declaration_from_name
       ImportError: No module named castxmlparser

One workaround is replace the 'bakeconf.xml' with the version corresponding to this changeset:

• http://code.nsnam.org/bake/rev/57644fa6e8aa

Python 3.7 and API scanning toolchain: ArchLinux has started to distribute Python 3.7, but there are issues with compatibility of the toolchain.

• https://www.nsnam.org/bugzilla/show_bug.cgi?id=2989

There is no present workaround other than piecing together the hints found in the above bug report.
