There are some deep DOMs you can hit the maximum nesting level
limit in tokenizeDOM (we've experienced this even with maximum nesting
level of 300). Here is an iterative version of the same function with
simple queue/dequeue approach.

The first bug is that we will repeatedly write out the result
of a customized raw definition to the filesystem, even when a cache
entry already exists.
The second bug is that caching these definitions doesn't actually
work (the cache entry is written but never used.) A new API
for retrieving raw definitions permits the user to take advantage
of caching.

HTML Purifier loads itself as the first autoload function by
unregistering all existing functions and re-registering them after
registering itself.
Originally an exception was thrown when a non-static object method was
encountered as the behaviour of spl_autoload_functions() did not return
the object instance, but only the class name. This was filed on PHP
bugs (#44144).
The bug was fixed for PHP >= 5.2.11 and >= 5.3

The new logic is as follows:
* Given a URL to insert into url(), check that it is properly URL
encoded (in particular, a doublequote and backslash never occurs
within it) and then place it as url("http://example.com").
* Given a font name, if it is strictly alphanumeric, it is safe to omit
quotes. Otherwise, wrap in double quotes and replace '"' with '\22 '
(note trailing space) and '\' with '\5C ' (ditto).
We introduce expandCSSEscape() which is a hack for common parsing
idioms in CSS; this means that CSS escapes are now recognized inside
URLs as well as unquoted font names.

YouTube slideshows contain a /cp/, not a /v/, in their URL;
relax the YouTube filter to allow them.

Previously, if two </body> tags were present, HTML Purifier
would truncate everything after the first </body>. This is
not ideal behavior; so HTML Purifier has been changed to
match up to the last </body>.

%URI.Munge incorrectly munged URIs that pointed to the
same host as the current website (it did, however, have
the correct behavior for when the munge URL was on the
same server).
