-												Add HTML parser support for HTML5 meta charset encoding declaration

For https://bugzilla.gnome.org/show_bug.cgi?id=655218

http://www.w3.org/TR/2011/WD-html5-20110525/semantics.html#the-meta-element

"""
The charset attribute specifies the character encoding used by the document.
This is a character encoding declaration. If the attribute is present in an XML
document, its value must be an ASCII case-insensitive match for the string
"UTF-8" (and the document is therefore forced to use UTF-8 as its
encoding).
"""

However, while <meta http-equiv="Content-Type" content="text/html;
charset=utf8"> works, <meta charset="utf8"> does not.

While libxml2 HTML parser is not tuned for HTML5, this is a simple
addition

Also added a testcase
