Reverting last change r231449 (fix bin/164947) due to concerns voiced
on src-committers and the fact that I can only take care of this in a
week.

Use err instead of errx when malloc fails. "malloc" is not a helpful
error message.

Revert part of the previous revision. Changing exit() to return() in main()
is wrong, even though our C compiler doesn't understand that exit() eats
control of the program, and as such can sometimes complain that main() reaches
the bottom of its body without an explicit return().

Aside from that, the functional usefulness of changing it is effectively nil,
so back it out.

Remove spurious casts in malloc(3)'s argument.

Use `return' instead of `exit' at the bottom of main().

Warns cleanups. Add FreeBSD ID to Makefile.
