Srivats P. 17792b8253 Refactoring, optimization et. al.
---------------------------------
	- StreamConfigDialog: Valid subsequent protocol choices for a particular protocol in the simple protocol selection widget is no longer hardcoded - ProtocolManager is queried for validitity of each pair of possible protocols; signal-slot connections are made accordingly. This refactoring makes it easier to add a protocol to the simple protocol selection widget
	- ProtocolManager: populates and maintains a database of valid 'neighbour protocols' and implements a method - isValidNeighbour() to query the same for a pair of protocols
	- AbstractProtocol: new method protocolIdType() introduced to build the above database (in conjunction with the existing method protocolId(ProtocolIdType)); default implementation returns ProtocolIdNone
	- Protocols which include a valid/supported ProtocolIdType (eth/llc/ip) reimplement protocolIdType() to return the apporpirate ProtocolIdType. These are viz.
		- combo
		- eth
		- llc
		- snap
		- ip
	- Speed optimization while populating streamqueues if the protocolFrameValue/Size() does not vary across packets
	- AbstractProtocol: new methods to support the above optimization
		- isProtocolFrameValueVariable()
		- isProtocolFrameSizeVariable()
		- isProtocolFramePayloadValueVariable()
		- isProtocolFramePayloadSizeVariable()
		(each of the default implementations returns false indicating that the protocol frame value or frame size is fixed and not variable)
	- Protocols which support variable values/size (list follows) reimplement the above methods appropriately
		- combo
		- mac
		- dot3
		- ip4
		- tcp
		- udp
		- payload
	- StreamInfo::makePacket() moved to base class as StreamBase::frameValue()
	- StreamBase: all 'get' accessor functions made 'const'
	- class ProtocolManager: while registering a protocol, no need to pass the protocol name; ProtocolManager finds it out internally by using the protocol's shortName() method



Fixes
-----
	- Fixed issue with port capture not starting the first time 'start capture' was clicked
