[xml] Release of libxml2-2.7.0

[Daniel Veillard <veillard redhat com>]

 Yes that's the end of the 2.6.x series (2.6.0 was released Oct 20 2003!)
There is a few big changes in the parser in that version which make
it worth bumping the mid version number:
  - the parser is switched to XML-1.0 5th edition, you should not notice
    the change, if it bothers you use the XML_PARSE_OLD10 parser flag
  - the URI parser is updated to RFC 3986, the WebDAV people won't get
    a warning because of their broken namespace name
  - the dictionaries have a new improved hash algorithm
  - there is a new entity non-linear detection algorithm which should
    protect effectively agaisnt billion laughts kind of attacks
  - there is a parser flag XML_PARSE_HUGE to drop hardcoded limits in
    the parser like maximum depth of a document or the entity recursion
