1e99d29f36 py/runtime: Allow multiple **args in a function call.
This is a partial implementation of PEP 448 to allow multiple ** unpackings
when calling a function or method.

The compiler is modified to encode the argument as a None: obj key-value
pair (similar to how regular keyword arguments are encoded as str: obj
pairs).  The extra object that was pushed on the stack to hold a single **
unpacking object is no longer used and is removed.

The runtime is modified to decode this new format.
