A little work still needs to be done on the new NCP dissector -- make some of the COL_INFO texts more useful, handle a Unicode issue, and modify some of the cases that use "request conditions". But the NCP dissector as it stands is very usable now. Note: I didn't merge in the PROTO_LENGTH_UNTIL_END macro... I wanted to think about the various possible macros and review an email conversation I had with Guy on the subject. svn path=/trunk/; revision=5432
