More cleanups: (#53)
- sprinkle const - add a macro (setptr) that cheats const to temporarily NUL terminate strings remove casts from allocations - use strdup instead of strlen+strcpy - use x = malloc(sizeof(*x)) instead of x = malloc(sizeof(type of *x))) - add -Wcast-qual (and casts through unitptr_t in the two macros we cheat (xfree, setptr)).
