Introduce Breakpad crash handler

Google Breakpad (https://chromium.googlesource.com/breakpad/breakpad) is a
widely used crash handler framework, e.g. by Mozilla and Chromium. It is
providing a platform neutral solution to generate mini dumps, collect
debug information and generate stack traces from those.

+"""Streaming HTTP uploads module.
+
+This module extends the standard httplib and urllib2 objects so that
+iterable objects can be used in the body of HTTP requests.
+
+In most cases all one should have to do is call :func:`register_openers()`
+to register the new streaming http handlers which will take priority over
+the default handlers, and then you can use iterable objects in the body
+of HTTP requests.
+
+**N.B.** You must specify a Content-Length header if using an iterable object
+since there is no way to determine in advance the total size that will be
+yielded, and there is no way to reset an interator.
+
+Example usage:
+
+>>> from StringIO import StringIO
+>>> import urllib2, poster.streaminghttp
+
+>>> opener = poster.streaminghttp.register_openers()
+
+>>> s = "Test file data"
+>>> f = StringIO(s)
+
+>>> req = urllib2.Request("http://localhost:5000", f,
+...                       {'Content-Length': str(len(s))})
