9f70f29499 Refactor ICMP/IGMP checksums 
Added a new CksumTypeIcmpIgmp and implemented it in AbstractProtocol.

a498dbf21a Fix incorrect UDP/ICMP checksums 
For UDP encaps like VxLAN or Geneve, which can contain IP as
payload, the UDP checksum was incorrect because when summing
UDP payload (i.e. IP), we skipped the IPv4 checksum field,
which should not be skipped in this case.

Similar issue, for ICMP with IP as payload, ICMP checksum was
incorrect.

Essentially, any protocol which checksums over its payload and
the payload contains protocols with checksum fields.

df24cf8b15 Feature: Variable Fields - any field of any protocol can now be varied by specifying it as a generic 8/16/32 bit field at a specified offset (relative to the protocol frame value) with a certain mask and a (initial) value alongwith count and step; this is working code - but incomplete. Bunch of FIXME/TODOs and testing pending 2015-05-26 21:43:37 +05:30

a9da643fb2 Feature: Reserve Ports for cooperative use of shared drone. If a port is reserved the GUI will display the username of the owner but others can still view and control the port; in other words, we just potentially prevent unintentional usage of other people's ports, users still need to play nice with each other!
