Code contributed by Matt Giuca. quote() now encodes the input
before quoting, unquote() decodes after unquoting. There are
new arguments to change the encoding and errors settings.
There are also new APIs to skip the encode/decode steps.
[un]quote_plus() are also affected.
It consists of code from urllib, urllib2, urlparse, and robotparser.
The old modules have all been removed. The new package has five
submodules: urllib.parse, urllib.request, urllib.response,
urllib.error, and urllib.robotparser. The urllib.request.urlopen()
function uses the url opener from urllib2.
Note that the unittests have not been renamed for the
beta, but they will be renamed in the future.
Joint work with Senthil Kumaran.
