caddress => fixed bug => default constructor used too short length value
crofconn => changed behaviour in method recv_message() => ignore connection state for certain messages
csocket_impl => revised logic for handling high load situations on writing to socket: drop messages, if transmission queue exceeds a certain threshold (default: 16 packets), crofconn => revised logic for sending Echo.requests: reset timer for sending Echo.requests, when a message from the peer entity was received in order to avoid excessive OAM life check traffic
crofchan, crofconn and crofsock => revised API, bug fixes around echo requests/replies, new class ctimerid for avoiding typical errors for timer-type and timer-id (which were both uint32_t before)
crofsock => receive multiple messages in a sequence, do a reschedule after a certain amount of messages (default: 16), configurable at compile time

crofqueue => added congestion function logic
crofqueue => renamed set_limit() to set_max_limit()
new class: cauxid, revised API for crofdpt and crofctl
crofdpt_impl, crofctl_impl => revised send methods, throws exceptions for congestion window == 0
added handle_write() method to chain of csocket, crofsock, crofconn, crofchan, crofdpt/crofctl, crofbase
