adjust debug output verbosity
move open call up in callback for earlier pcap hdr check
allow for empty endfile in getattr and access callbacks

this allows files to end with ..
considering whether this should be a signal to act like followdir or prevent it
leaning towards acting, as .. is the range indicator, so user is specifying a range without an endpoint
appending the .. to a file could manifest as an increase in filesize from the actual size
change stat filesize only if files have .. appended

a null endFile (eg filename..) gives max filesize (no endFile known yet)
a valid endFile (eg filename..file2) can give actual estimate (yet TODO)
add to be developed filematch option
