- Move config.h and util.h from libyasm (and installed libyasm) to top level. - Move yasm_* functions from util.h to coretype.h. - Remove a number of autoconf-related YASM_*_INTERNAL options from libyasm.h. - Rename YASM_INTERNAL to YASM_LIB_INTERNAL; it now actually means what the comment describes: enables definitions that violate the yasm_* namespace. While we're at it, no longer define YASM_LIB_INTERNAL from yasm frontend, so it's closer to what a real typical libyasm-using application would look like. svn path=/trunk/yasm/; revision=944
