Jeremy Hylton 5477f529d6 Revise implementations of getChildren() and getChildNodes().
Add support for floor division (// and //=)

The implementation of getChildren() and getChildNodes() is intended to
be faster, because it avoids calling flatten() on every return value.
But it's not clear that it is a lot faster, because constructing a
tuple with just the right values ends up being slow.  (Too many
attribute lookups probably.)

The ast.txt file is much more complicated, with funny characters at
the ends of names (*, &, !) to indicate the types of each child node.

The astgen script is also much more complex, making me wonder if it's
still useful.

Jeremy Hylton 9c048f9f65 Now supports entire Python 2.0 language and still supports Python
1.5.2.  The compiler generates code for the version of the interpreter
it is run under.

ast.py:
    Print and Printnl add dest attr for extended print
    new node AugAssign for augmented assignments
    new nodes ListComp, ListCompFor, and ListCompIf for list
        comprehensions

pyassem.py:
    add work around for string-Unicode comparison raising UnicodeError
        on comparison of two objects in code object's const table

pycodegen.py:
    define VERSION, the Python major version number
    get magic number using imp.get_magic() instead of hard coding
    implement list comprehensions, extended print, and augmented
        assignment; augmented assignment uses Delegator classes (see
        doc string)
    fix import and tuple unpacking for 1.5.2

transformer.py:
    various changes to support new 2.0 grammar and old 1.5 grammar
    add debug_tree helper than converts and symbol and token numbers
    to their names

Jeremy Hylton be317e615e patches from Mark Hammond
Attached is a set of diffs for the .py compiler that adds support
for the new extended call syntax.

compiler/ast.py:
CallFunc node gets 2 new children to support extended call syntax -
"star_args" (for "*args") and "dstar_args" (for "**args")

compiler/pyassem.py
It appear that self.lnotab is supposed to be responsible for
tracking line numbers, but self.firstlineno was still hanging
around.  Removed self.firstlineno completely.  NOTE - I didnt
actually test that the generated code has the correct line numbers!!

Stack depth tracking appeared a little broken - the checks never
made it beyond the "self.patterns" check - thus, the custom methods
were never called!  Fixed this.

(XXX Jeremy notes: I think this code is still broken because it
doesn't track stack effects across block bounaries.)

Added support for the new extended call syntax opcodes for depth
calculations.

compiler/pycodegen.py

Added support for the new extended call syntax opcodes.

compiler/transformer.py

Added support for the new extended call syntax.
