package and setting __path__.

(mostly stuff specified by PEP 302). There are two ABCs, PyLoader and
PyPycLoader, which help with implementing source and source/bytecode loaders by
implementing load_module in terms of other methods. This removes a lot of
gritty details loaders typically have to worry about.

source/bytecode paths and what to do when they don't exist.

Fixed a bug where 'self' was left off a method call. Was masked by the fact the
source/bytecode loader subclass is always used. Cleaned up when the source path
is fetched. Also made sure ImportError is raised when a source path cannot be
found.

(please note: some of the tests /do/ fail when run with a sufficiently large memory parameter (-M),
perhaps because of the str/bytes/bytearray overhaul)
