* The "__builtins__" of standalone modules also must be a dictionary and
not the module.
* When modules error exit, must return NULL, not the module object, or
else Python3 will declare a SystemError instead.
* Program tests that are allowed to fail, because that is what they test
were not properly ported to Python3 compatibility.
* The symbol Py_Ticker was only defined inside an #ifdef that is not
proper at all.
* Removed copyright notice from inline copy of Scons, added by accident only
* Claim stronger copyright over basic, program, and reflected tests to release
them under public domain.
* Updated debian/copyright to include "odict" and "oset" licenses, and
full text for ARM ucontext parts
* Remove benchmarks from Debian package, too diverse licenses and not for
users.
