1) Restructure lib_mod_connect() along the lines of the PDUs documented in RFC 6143. 2) Logging in lib_mod_connect() has been revised and improved. 3) Wrinkles around version 3.7 and 3.8 of the RFB protocol are now addressed. 4) Some new definitions are added to rfb.h to replace the use of magic numbers.
