Guy Harris e85f05b0ec From Lars Roland: use the generic filter dialog for the SIP, HTTP, WSP, 
and BOOTP taps.

Get rid of the "dlg" variable in some of those taps - it's never set, so
it's always null, and nothing useful is done with it if it's null.

Make static some variables and functions not used outside the source
file in which they're defined.
