Changes in Python 3 that made the code choke:
o basestring is merged into str
o print() needs parentesis
o Class inheritance syntax changed
o Abstract baseclass (ABCMeta) syntax changed
o map.iteritems() is replaced by map.items()
o Inconsistent use of tabs and spaces are no longer tolerated

run_sub_commands() was the only way to access subcommands up to now,
Cmds.run() adds another interface, an object as a place to add
customizations affecting all commands, e.g. global command line
options.

into grammar.py, Cmd.py, and generate-flex-bison.mk.
