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)

1357f495ac Major rewrite of the protocol framework - changes not yet complete
Common
------
- Change in OstProto
	- Individual protocols are now extensions of (new) message 'Protocol' instead of 'Stream'
	- Stream now contains a repeated Protocol which also determines the ordered set of currently selected protocols; StreamCore.frame_proto which was doing this earlier has been removed

- Change in AbstractProtocol Interface
	- Parent changed to StreamBase
	- Corresponding change in constructor and factory func - createInstance()
	- new method protocolNumber() - returns unique id for each protocol
	- protoDataCopyInto/From() now copies into OstProto::Protocol instead of OstProto::Stream
- Change in all subclasses of AbstractProtocol to match new interface
- For all protocols, configFrom is no longer static, but each protocol has its own configForm
	- configForm creation is lazy
	- configForm is still a child of the protocol i.e. it will be destroyed alongwith the protocol
	- TODO: convert configWidget() to a pure factory function i.e. the protocol does not own the configForm - this requires us to pass the widget into load/storeConfigWidget() methods

- ProtocolCollection class removed alongwith its .h and .cpp
- ProtocolList class redefined to serve the purpose of ProtocolCollection
- New class ProtocolListIterator defined to iterate ProtocolList
- AbstractProtocol methods now use the ProtocolListIterator
- Factory function createProtocol() added to ProtocolManager
- OstProto::StreamCore accessor functions moved from Stream to StreamBase

Server
------
- MyService uses the newly moved accessors to StreamBase for OstProto::StreamCore members
- StreamInfo now uses the protocols to create the packet

Client
------
- StreamConfigDialog now uses ProtocolListIterator
- So does PacketModel

0103696016 - AbstractProtocol
- new method: fieldFlags() - isCksum, isMeta; Note: isMeta is a flag now not a attrib
	- fieldData() bit fields are now in lsb not msb - protocolFrameValue() and subclasses changed accordingly
	- protocolFrameValue() now takes an additional bool param indicating whether the frameValue is being requested for a checksum calculation; if so fields which are checksum fields are assumed to be zero and their value is not fetched to prevent infinite recursion
- Other Protocols
	- mac: srcMac/dstMac modes is now working
	- vlan: implemented VLAN protocol
	- ip4: src/dst Addr modes is now working
	- udp/tcp: checksum done
	- Basic testing done for MAC, VLAN, IPv4, UDP and TCP protocols
	- sample protocol: .cpp/.h added to repos - need to be made compilable
- StreamConfigDialog
	- Redesigned the protocol selection tab to accomodate "Advanced Protocol Selection"
	- L2 Tab config widgets are now in 2 columns
	- Packet Tree View is no longer collapsed if selected protocols don't change
