Code clean-up. * ma/t1300-cleanup: t1300: don't needlessly work with `core.foo` configs t1300: remove duplicate test for `--file no-such-file` t1300: remove duplicate test for `--file ../foo`

dnl Check for socklen_t: historically on BSD it is an int, and in
dnl POSIX 1g it is a type of its own, but some platforms use different
dnl types for the argument to getsockopt, getpeername, etc. So we
dnl have to test to find something that will work.
