ntp: add support for NTP over PTP
Allow NTP messages to be exchanged as a payload of PTP messages to
enable full hardware timestamping on NICs that can timestamp PTP packets
only. Implemented is the protocol described in this draft (version 00):
https://datatracker.ietf.org/doc/draft-mlichvar-ntp-over-ptp/
This is an experimental feature. It can be changed or removed in future.
The used PTP domain is 123 and the NTP TLV type is 0x2023 from the "do
not propagate" experimental range.
The ptpport directive enables NTP-over-PTP as a server and as a client
for all sources that have the port option set to the PTP port. The port
should be the PTP event port (319) to trigger timestamping in the
hardware.
The implementation is contained to ntp_io. It is transparent to
ntp_core.

ntp: add PTP rxfilter
Setting rxfilter to ptp enables timestamping of PTPv2 packets (UDP or
all transports). It will be needed for NTP-over-PTP support.
commit b2c2132e4b2e18e237d1e1823bde2bfa693505e8
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>

ntp: provide remote port to NIO_OpenServerSocket()
This will allow selection of different protocols based on the remote
port. Zero means the default (NTP).
