loops, so we mark frames as short if they've been cut short by a snapshot length. The user class in buddy list TLVs appears to be 2 bytes, in at least some captures; make "dissect_aim_userclass()" take the user class value, and the length of the user class field, as arguments, and have the caller fetch the value. Also, display the numerical value of the user class in hex, as it's a bitset. Fix the messaging dissector to put stuff under the top-level item rather than at the top level. Fix a typo. Clean up indentation. svn path=/trunk/; revision=10802
