Heap-based buffer overread in xmlDictAddString

https://bugzilla.gnome.org/show_bug.cgi?id=758605

Reviewed by David Kilzer. 

* HTMLparser.c: 
(htmlParseName): Add bounds check. 
(htmlParseNameComplex): Ditto. 
* result/HTML/758605.html: Added. 
* result/HTML/758605.html.err: Added. 
* result/HTML/758605.html.sax: Added. 
* runtest.c: 
(pushParseTest): The input for the new test case was so small 
(4 bytes) that htmlParseChunk() was never called after
htmlCreatePushParserCtxt(), thereby creating a false positive test failure. Fixed by using a do-while loop so we always call htmlParseChunk() at least once. 
* test/HTML/758605.html: Added.
