the basic reporting functions that share the same signature. This also resulted
in eliminating a string, and adding a new string to disambiguate between

This appears to be an issue with Word2000 handling of empty attributes.
A reproduction case can be seen here:
```
$ cat test.html
<html xmlns:o="urn:schemas-microsoft-com:office:office">
<body>
<table>
<img class="" />
</table>
</body>
</html>
$ ./tidy --tidy-mark no --word-2000 yes test.html
line 1 column 1 - Warning: missing <!DOCTYPE> declaration
line 3 column 1 - Warning: <img> isn't allowed in <table> elements
line 2 column 1 - Info: <table> previously mentioned
line 1 column 57 - Warning: inserting missing 'title' element
line 3 column 1 - Warning: <img> lacks "alt" attribute
line 3 column 1 - Warning: <img> lacks "src" attribute
line 2 column 1 - Warning: trimming empty <table>
line 1 column 1 - Warning: <html> proprietary attribute "xmlns:o"

(It is technically undefined behaviour to call strncmp with `NULL` pointers however).
the remainder of the callbacks. TidyConfigCallback is now given a reference
to the instance of the TidyDoc that caused the callback to occur.

An earlier patch now passes back an all space text node. Previously this
would have been skipped. So add code in ParseList to detect, and discard
such a node.
Change committed:
modified: src/parser.c
Add option TidyStyleTags, --fix-style-tags, Bool, to turn off
this action.
Add warning messages MOVED_STYLE_TO_HEAD, and FOUND_STYLE_IN_BODY.
Fully iterate ALL nodes in the body, in search of style tags...
