From e533fad711fce66bf2e4a6669baeb8eaf02799e1 Mon Sep 17 00:00:00 2001

Subject: Significant rework of Packet class interface: - new constructor
 guarantees initialization of most fields - flags track status of
 non-guaranteed fields (addr, size, src) - accessor functions (getAddr() etc.)
 check status on access - Command & Result classes are nested in Packet class
 scope - Command now built from vector of behavior bits - string version of
 Command for tracing - reinitFromRequest() and makeTimingResponse()
 encapsulate common manipulations of existing packets
