v0.45.1

Bug fixes:

• rlwrap would always open /tmp/rlwrap.debug after forking child command, preventing other users from running it.
• Fix args to setitimer() call to prevent EINVAL error on return
• advise about --always-readline if in direct mode at first user ENTER keystroke
• check for I_SWROPT even if isastream() is present (compile would fail on Oracle linux)
