jmemsys.h: Remove unused MS-DOS/Mac mem. mgr. code Those obsolete memory managers have never been included in libjpeg-turbo, nor has libjpeg-turbo ever claimed to support MS-DOS or Mac operating systems prior to OS X 10.4 "Tiger." Note that we retain the ability to use temp files, even though libjpeg-turbo does not use them. This allows downstream implementations to write their own memory managers that use temp files, if necessary.
