Au_read.readframes() now updates current file position and reads correct
number of frames from multichannel stream.  Au_write.writeframesraw() now
correctly updates current file position.  Au_read.getnframes() now returns an
integer (as in Python 2).  Au_read and Au_write now correctly works with file
object if start file position is not a zero.

This patch appropriately marks known false alarms in the
small object allocator when address sanity checking is
enabled (patch contributed by Dhiru Kholia).

- this was an internal implementation detail for iterparse
- this has been changed to use a new private method instead
- XMLPullParser.close docs are now more explicit about not
  returning a root element and instead direct users towards
  read_events
- also added missing docstrings and clarified some details
  related to exactly *when* events are consumed from the
  internal queue

Issues such as iterating and containment on Enum classes, why Enum member
instances do not show up on other Enum members, and how __new__ should
be used.

and can't bootstrap the parser.

1. Make it work when invoked directly from the command-line. It was failing
   due to a couple of stale function/class usages in the __main__ section.
2. Close the parsed file in the parse() function after opening it.

inspect.getmembers and inspect.classify_class_attrs now search the metaclass
mro for types.DynamicClassAttributes (what use to be called
enum._RouteClassAttributeToGetattr); in part this means that these two
functions no longer rely solely on dir().

Besides now returning more accurate information, these improvements also
allow a more helpful help() on Enum classes.

Also slight code reorg for PEP 8 guidelines.
