disas.py:
- disassembles *all* code objects found
scanner*.py:
- no longer need to pass in version numbers; this
is obtained from the class name
- no longer pass in opcodes; this is done at
initialization from the scanner name
- all Pythoin 3 scanners support native disassembly
into a string. parse3.py: handle both keyword and positional function
calls. scanner34.py: Remove extra level of quoting in LOAD_CONST.
Keyward handling now works cross Python 2/3. Some other spelling and doc fixes.
Remove duplicate disassembly printing from scanners and
put common code in caller(s). Show source-code line numbers in disassembly output
and fix alignment of byte offsets.
disas.py: workaround Python 2/3 different layouts before we get to
bytecodes in a code object.
