Commit Message

Implement missing HDLC ABM protocol features

Add DM (Disconnect Mode) frame support:
- Send DM response when I/S-frames arrive in disconnected state
  instead of auto-reconnecting with SABM (per ISO 13239)
- Handle incoming DM frames by transitioning to disconnected state

Complete FRMR (Frame Reject) handler:
- On FRMR reception, disconnect and initiate link reset via SABM

Implement RSET (Reset) handler:
- Reset sequence numbers (V(S), V(R)) on RSET reception
- Respond with UA frame as required by spec

Add RNR (Receive Not Ready) S-frame recognition:
- Confirm frames up to N(R) but do not trigger further sends
- Enables peer busy flow control signaling

Update proto logger to recognize DM and RNR frame subtypes.

Update and expand unit tests:
- Rename ABM_SendSABMOnIFrameIfDisconnected to ABM_SendDMOnIFrameIfDisconnected
- Add ABM_SendDMOnSFrameIfDisconnected
- Add ABM_FRMRReceiveTriggersReconnect
- Add ABM_RSETResetsSequenceNumbers
- Add ABM_RNRPausesTransmission
- Add ABM_DMReceiveDisconnects
