* start working on tracking down tcp buffer bug
* mtu refactor
* modularize test
* more precise testing
* tests fail, but is it the failure we are looking for?
* fix typo in espradio link (#76)
* implement a new backoff abstraction (#75)
* rewrite backoff api
* rewrite tcp.Conn.Write
* keep fixing small things
* much better Conn.Read implementation
* fix critical overflow bug in internal.ConnRWBackoff

* tcp: remove retransmit logic entirely; add duplicate ack counting to ControlBlock
* retransmit implemented in nice simple straightforward way
* narrow down retransmission cases
* remove old timing tests
* add ControlBlock retransmit test
* add failing handler test
* reworking payload length semantic meaning in code
* fix establish conn logic
* clean up tests and add TCB dupack generation and test it
* catch pending retransmit satisfy in test
* add fuzz test for control block
* bugfix: be more strict in what is considered dupack
* add IncomingIsDupACK docs
* limit queue of retransmits
* protect retransmit overflow from incorrectly updating nxt
* fix for #58
* add fixes for both retransmit and fuzz failure found
* fix infinite challenge ack due to RST+SYN+FIN corrupt packet in SYNRCV state
* fuzz: previous recovery ack path led to infinite transmit
* fuzz: calculate CRCs when fuzzing to reduce search space to non-CRC error cases
* add local fuzz corpus to tests
* add more cases to fuzz corpus
* tcp: bugfix for seq not in snd/rcv.wnd error
* accept dupe ACKs for window updates and prevent decrement of UNA
* add fixes for incorrect tcp functioning
* remove Conn.Available* methods in favor of Conn.Free* methods due to ambiguous name
* pcap: reuse Frame memory
* slog: reduce heap allocations of addresses; also prevent heap alloc of dhcp options in pcap
* dns: heapless improvement; add StackAsync buffer for more heapless operation; start thinking of errors
* errors: begin standardise errors in lneto
* errors: finish standardization of errors
* fix merge issues
* add more lneto errors to rest of package
* format errors.go
* reduce heap allocations in tcp logging; omit use of AppendFloat which allocates a metric sh*tton
* debugheaplog: better heap statistic logging
* heap: use string for pcap.Frame.Protocol
* add potential to eliminate Flags.String heap alloc, remove incorrect HEAP comments
* add StackAsync.DebugErr and httpraw.SetBytes
* many heap alloc reductions and replacement of bytes.Equal with internal.BytesEqual
* do not rely on unspecified Go behaviour; fix TCP ring buffer bug
* even more stricter error handling on tcp connections
* stricter lock copying in tcp.Conn, even though likely not a problem
* add listener and tcp pool logging
* forgot reqAddr unused
* add logging to TCPConn and friends
* begin reviewing TCP listener
* begin adding listener tests
* adding TestExchange implementation
* split out legacy and Step tests
* move listener to tcp package
* fix up tcp tests taking very long
* add xnet.TCPPool and work on TCPPool semantics
* xnet: TCPPool only accepts established connections
* xnet: getting to bottom of panic in xnet.Listener
* xnet: improve listener tests
* fix several data races in testing fixtures
* fix more synchronization things in listener test
* finalize tcplistener test
