Summary: ast-branch: multiple function fixes

Initial Comment:
This patch fixes:

- handling of keywords, varargs, and kwargs on function 
definition
- handing of keywords, varargs, and kwargs on function 
call
- handling of keywords for lambdas
- function chaining (foo().bar().baz())

Applying this uncovers some another bug that at least:

- cause a core dump upon import of  sre_parse
- cause an infinate loop upon import of ntpath

I believe I've tracked down the problem to the 
generation of bad bytecode for nested loops, as in:

for x in 1,2:
    for y in 3,4:
        print x,y

This causes problems with Subpattern.dump() in 
sre_parse and ntpath's commonprefix().

I'll try to figure out what's wrong with nested loops next.
