cleaned_data is no longer deleted when form validation fails but only
contains the data that did validate.
Thanks to the various contributors to this patch (see ticket).
This applies to both our own [test] code and documentation examples. Also:
* Moved the functions and handlers from `django.conf.urls.defaults` up to
`django.conf.urls` deprecating the former module.
* Added documentation for `handler403`.
* Tweaked the URLs topic document a bit.
Thanks to pupeno and cdestigter for their great work contributing patches.

This ought to have been done in [14218], but although the FormPreview class
was modified, and some tests were added, the crucial lines of code were not
changed (the 'FormPreview.security_hash' method), and tests for the new
behaviour were not added. So it is being changed now. Unlike some of the
other code in that changeset, this does not need to have a compatibility
fallback to cope with existing hashes, because the consequence of a failed
hash is minimal - the user is re-presented with the preview stage of the
form, which will then have a correct hash.

Without these checks, it is possible for the tests to pass by virtue of
asserts never being reached for some reason (very possible in this case, due
to handling of security hashes).

This commit adds several new hooks in backwards-compatible way:
* get_initial to specify initial data based on request
* get_auto_id to enable different AUTO_ID values
* get_context for overriding and extending default context contents

All adhoc MAC applications have been updated to use HMAC, using SHA1 to
generate unique keys for each application based on the SECRET_KEY, which is
common practice for this situation. In all cases, backwards compatibility
with existing hashes has been maintained, aiming to phase this out as per
the normal deprecation process. In this way, under most normal
circumstances the old hashes will have expired (e.g. by session expiration
etc.) before they become invalid.
In the case of the messages framework and the cookie backend, which was
already using HMAC, there is the possibility of a backwards incompatibility
if the SECRET_KEY is shorter than the default 50 bytes, but the low
likelihood and low impact meant compatibility code was not worth it.
All known instances where tokens/hashes were compared using simple string
equality, which could potentially open timing based attacks, have also been
fixed using a constant-time comparison function.
There are no known practical attacks against the existing implementations,
so these security improvements will not be backported.
