Changes since 1.213:	+8 -5 lines
Log Message:	- restore after combined mainboard+harddisk crash - cleanup/fixes for 2.1 release - fix invoke to actually do work - refactor invoke shortcuts, gcc cannot inline varargs functions. - optimised invoke to 4-5 insns in the common case. - optimised (For no good reason) the int-to-ascii conversions of dynbuf_text into division-less and branchless code (of which I am pretty proud). - actually move players to their savebed when they did not use one and the map has been reste in the meantime. does not kill (yet) when too long. - enter_map is now handled completely in perl. - goto is now using generation counting to ensure that only the most-recently-issues goto will succeed. - make some heavy use of __builtin_expect to streamline rare callbacks even more. - optimised thawer.
