Srivats P. 0094f618d3 Protocol Framework related
--------------------------
	- AbstractProtocol Constructor and Factory function now take an optional (default NULL) "parent" abstract protocol in addition to the stream; this "parent" protocol is non-NULL for protocols which are aggregated in a ComboProtocol
	- All subclasses of AbstractProtocol modified as per the above interface change
	- ProtocolManager also modifed as per the above interface change
	- new data members in AbstractProtocol - prev, next; the AbstractProtocol implementation now uses these members to traverse protocols on the list instead of ProtocolListIterator; this change required for ComboProtocol
	- ProtocolListIterator updates these new members - prev/next on insert/remove/replace
	- ComboProtocol and ProtocolListIterator classes made friends of AbstractProtocol
	- ComboProtocol implemented as a template class (completed)
	- Dot2LLc implemented as a combo of Dot3Raw and LLC
	- Dot2Snap implemented as a combo of Dot2Llc and SNAP
	- VlanStack implemented as a combo of VLAN + VLAN
	- ProtocolManager now uses the ProtocolId enums rather than hardcoded values

Stream Config Dialog
--------------------
	- "None" radio button added to all protocol levels
	- Protocol Level 1 added with 'mac' as the only valid protocol in the "simple" mode widget
	- With Dot2Llc, Dot2Snap and VlanStack implemented as "combo" protocols, the protocol choice radiobuttons in the "simple" mode are now 1:1 with a protocol; this has the following implications/advantages:
		- Updates of the "simple" mode widget from/to stream's protocolList is simpler; this code has now been rewritten to take advantage of 1:1
		- This paves the way for exporting tunneled protocols 4over4, 4over6, 6over4 etc. in the "simple" mode
		- This should also (hopefully) require less changes when adding a new protocol; more work needs to be done to reach this goal

Fixes
-----
	- Dot3Protocol now derives "length" correctly for VLAN tagged packets
	- StreamBase now uses the ProtocolListIterator to append the default protocols in a stream instead of directly manipulating ProtocolList; also in protoDataCopyFrom()

Others (Client/Server)
----------------------
	- Port Packet Capture implemented; "view capture" is pending (hack put in place now for testing)
