Spec file fixes for EL6
Spec file improvements for Debian/Ubuntu pkg-config
Tlog-play improve authentication options
Handle piped in I/O from stdin and improve the main recording
transfer exit condition.
Use empty string on hostname resolution failure
Allow tlog-play redirection of stdout
Add -i/--interactive option to tlog-rec-session. Allows login
programs to call tlog-rec-session more transparently.
