Enhance/fix VMS setting of program name, MAKE/MAKE_COMMAND variables
* default.c, main.c, makeint.h, vmsfunctions.c: prefix argv[0] with "mcr " for MAKE/MAKE_COMMAND and set the program name to the image filename (without the .exe;version) * vmsfunctions.c: remove obsolete code * vmsify: use xmalloc
