libvlc: remove "evil" daemon global variable and clean up

(The unlikely corner case of ENOMEM remains unhandled/unfixed.)
libvlc: look the value of intf up only once when used
libvlc: look "syslog" value only once, simplify
intf-add: small simplification
pl_CurrentInput: more specific prototype
dbus: use pl_CurrentInput()
str_format_meta: clean up
str_format_meta: take input thread pointer rather than playlist
input_CreateFilename: take explicit input thread pointer

This should fix meta-data expansion in LibVLC (i.e. when recording).
Remove faulty return when vobsub doesn't define a size.
