My intention of renaming as actually to keep the  original names, but just add a prefix to it. That way it's both clear what functions in libhtp we need to keep an eye on, and also that the functions are a copy.

So something like:
SC_htp_is_lws()
Alternatively we can just use our normal scheme w/o the SC prefix.
HtpIsLws(), 

Considering my original goal I would prefer the first scheme, even if it's ugly as hell :-/
