Clean up malloc(3)'s argument. Remove casts which do nothing when we're

Browse Source 
using sizeof() anyway.  Use slightly more consistent (per-file) error
reporting for malloc(3) returning NULL.  If "malloc failed" was being printed,
don't use err(3).  If a NULL format is being used, use err(3).  In one case
errx(3) was being used with strerror(3), so just use err(3).
