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
