Updating CHANGES and chaning VERSION to v0.4.3
Merge remote-tracking branch 'origin/devel-0.4' into devel-0.5

rofl exceptions => implementation of methods what() in all rofl exceptions completed
croflexception.h => minor clean-up
Merge branch 'devel-0.5' into akoepsel/devel-0.5/working
Attempting to fix caddress.h/c endianness issues (BIG_ENDIAN)
added assertions to the socket implementations
Merge remote-tracking branch 'origin/devel-0.5' into endianness_endpoint
Fixing setters
buffer-ids should be OFP_NO_BUFFER, when they are not in response of a PKT_IN. Perhaps default buffer_id in rofl::openflow::cofflowmod should be OFP_NO_BUFFER
Fixing unused variable 'tmp' on some compilers when compiled without debug
Fixing unused variable 'addr' in of1x_action.c on some compilers when compiled without debug
check for NULL

next_timeout can be NULL if there are no timeouts
