 gh-135661: Fix parsing start and end tags in html.parser.HTMLParser
 according to the
 HTML5 standard.

         Whitespaces no longer accepted between </ and the tag name. E.g.
 </ script> does
 not end the script section.

         Vertical tabulation (\v) and non-ASCII whitespaces no longer
 recognized as
 whitespaces. The only whitespaces are \t\n\r\f and space.

         Null character (U+0000) no longer ends the tag name.

         Attributes and slashes after the tag name in end tags are now
 ignored, instead
 of terminating after the first > in quoted attribute value. E.g.
 </script/foo=">"/>.

         Multiple slashes and whitespaces between the last attribute and
 closing > are
 now ignored in both start and end tags. E.g. <a foo=bar/ //>.

         Multiple = between attribute name and value are no longer
 collapsed. E.g. <a
 foo==bar> produces attribute “foo” with value “=bar”.

 gh-102555: Fix comment parsing in html.parser.HTMLParser according to the
 HTML5
 standard. --!> now ends the comment. -- > no longer ends the comment.
 Support abnormally
 ended empty comments <--> and <--->.

 gh-135462: Fix quadratic complexity in processing specially crafted input
 in
 html.parser.HTMLParser. End-of-file errors are now handled according to
 the HTML5 specs
 – comments and declarations are automatically closed, tags are ignored.

 gh-118350: Fix support of escapable raw text mode (elements “textarea” and
 “title”) in
 html.parser.HTMLParser.
