Thanks, I clarified the split error messages in the first one a bit.

ecalloc does not call die() on failure. It just prints the errno string without
a prefix and then returns NULL. Should we change that to call die() instead? It
would simplify some cases in sent at least, where we currently call
malloc/calloc and check the return code. Is there a case in the other projects
where we don't want to die() on allocation failures? If there are just a few,
they might switch back from ecalloc to calloc. Another option might be to
introduce wecalloc like weprintf in sbase.
