HEAD
Message cleanup Jumbo Diff:
- in xmlerror.h : I added the export of an error context type (void *)
an error handler type xmlGenericErrorFunc
there is an interface
xmlSetGenericErrorFunc (void *ctx, xmlGenericErrorFunc handler);
to reset the error handling routine and its argument
(by default it's equivalent to respectively fprintf and stderr.
- in all the c files, all wild accesses to stderr or stdout within
the library have been replaced to the handler.
- removed slashrdf.c now obsolete

*
* Dirty macros, i.e. one need to make assumption on the context to use them
*
* CUR_PTR return the current pointer to the xmlChar to be parsed.
* CUR returns the current xmlChar value, i.e. a 8 bit value if compiled
* in ISO-Latin or UTF-8, and the current 16 bit value if compiled
* in UNICODE mode. This should be used internally by the parser
* only to compare to ASCII values otherwise it would break when
* running with UTF-8 encoding.
* NXT(n) returns the n'th next xmlChar. Same as CUR is should be used only
* to compare on ASCII based substring.
* UPP(n) returns the n'th next xmlChar converted to uppercase. Same as CUR
* it should be used only to compare on ASCII based substring.
* SKIP(n) Skip n xmlChar, and must also be used only to skip ASCII defined
* strings within the parser.
*
* Clean macros, not dependent of an ASCII context, expect UTF-8 encoding
*
* CURRENT Returns the current char value, with the full decoding of
* UTF-8 if we are using this mode. It returns an int.
* NEXT Skip to the next character, this does the proper decoding
* in UTF-8 mode. It also pop-up unfinished entities on the fly.
* COPY(to) copy one char to *to, increment CUR_PTR and to accordingly
