patched to redirrect all "out of context" error messages to
a reconfigurable routine. The changes are:
* xmlerror.h : 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.
* all the c files: all wild accesses to stderr or stdout within
the library have been replaced to calls to the handler.
