Implements the Peer-to-Peer (P2P) transparent clock delay measurement mechanism (IEEE 1588-2008 §11.4 / IEEE 802.1AS / IEC/IEEE 61850-9-3) in apps/netutils/ptpd: - Add PTP_MSGTYPE_PDELAY_REQ, PTP_MSGTYPE_PDELAY_RESP, and PTP_MSGTYPE_PDELAY_RESP_FOLLOW_UP definitions and structs in ptpv2.h. - Define IEEE 1588-2008 Annex F peer delay multicast MAC address 01:80:c2:00:00:0e and Annex D peer delay IP address 224.0.0.107. - Replace bool delay_e2e with enum ptp_delay_mechanism_e (PTP_DELAY_NONE, PTP_DELAY_E2E, PTP_DELAY_P2P) in include/netutils/ptpd.h. - Add -P CLI option in system/ptpd/ptpd_main.c with mutual exclusion check against -E, and display last_transmitted_pdelayreq in status. - Implement responder logic in ptp_process_pdelay_req() sending Pdelay_Resp (t2) and Pdelay_Resp_Follow_Up (t3) regardless of master or slave state. - Implement requester logic in ptp_send_pdelay_req() gated on the physical link without requiring prior BMCA master selection. - Implement ptp_process_pdelay_resp() and ptp_process_pdelay_resp_followup() using canonical mean path delay formula ((t4 - t1) - (t3 - t2)) / 2. - Refactor path delay bounds checking and moving average filter into ptp_record_path_delay() shared across E2E and P2P mechanisms. - Set PTP version 2.0 and controlField 0x05 in Pdelay_Req, Pdelay_Resp and Pdelay_Resp_Follow_Up, and in the own-identity header, so that peers such as linuxptp accept the messages. - Clear pdelay_waiting_followup when a new Pdelay_Req is sent, so an orphaned Pdelay_Resp_Follow_Up from an abandoned cycle is not paired with stale timestamps. - Warn at startup when P2P is selected without CONFIG_SCHED_TICKLESS, since a tick-driven clock cannot resolve the peer delay. - Skip IP multicast join/leave handling for AF_PACKET.
