Luke Plant cb060f0f34 Fixed #15258 - Ajax CSRF protection doesn't apply to PUT or DELETE requests 
Thanks to brodie for the report, and further input from tow21

This is a potentially backwards incompatible change - if you were doing
PUT/DELETE requests and relying on the lack of protection, you will need to
update your code, as noted in the releaste notes.

Luke Plant 45c7f427ce Fixed #14445 - Use HMAC and constant-time comparison functions where needed. 
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.

Luke Plant 364583b894 Fixed #14235 - UnicodeDecodeError in CSRF middleware 
Thanks to jbg for the report.

This changeset essentially backs out [13698] in favour of a method that
sanitizes the token rather than escaping it.

Luke Plant e8cff0b8f3 Added explanatory note on CSRF failure page for the case of a missing Referer header. 
This is intended to help power users who have disabled Referer headers, or
installed add-ons which have done so, and to help web site administrators
with debugging, since this problem will be browser specific and not a
programming error.

Luke Plant 7230a995ce Moved contrib.csrf.* to core code. 
There is stub code for backwards compatiblity with Django 1.1 imports.

The documentation has been updated, but has been left in
docs/contrib/csrf.txt for now, in order to avoid dead links to
documentation on the website.
