Introduce some default parser limits

Those can be overrided by the XML_PARSE_HUGE option, they
are just default limits for Name lenght, dictionary size limits
and maximum amount of parser lookup.
* include/libxml/parserInternals.h: define the limits
* include/libxml/xmlerror.h: add a new error
* parser.c parserInternals.c: implements the new limits
