Avoiding reading of messages that have not been fully received in the channel buffer.
Renamed packages of generated code to org.projectfloodlight.openflow.*
And made LENGTH, MINIMUM_LENGTH, WIRE_VERSION constants package private instead of private to avoid 'unused' warnings.
Package renaming - missed the pre-written files in the previous commit.
Merge into master from pull request #52:
Fixes for java loxigen - buffer reading and package name (https://github.com/floodlight/loxigen/pull/52)
