* bugfix: correct SCAMPER_DL_IS_ICMP_TIME_REPLY macro so that scamper
does not ignore ICMP replies quoting TCP/UDP packets for 1/256
source port values.
* bugfixes for -O icmp-rxerr: handle EPOLLERR on linux, try using
IPV6_RECVHOPLIMIT before IPV6_HOPLIMIT for IPv6 udp probing.
* bugfix: fix possible assertions in dealias, trace, and tracelb code.
* ping: count UDP replies as from the target
* trace: correct datalink timestamp adjustments
* add more specific error messages when a scamper command is not
accepted, return them over control socket or terminal, as appropriate.
* scamper_fd_t: refactor fd_addr, fd_sport, fd_dl, fd_ifindex
* scamper_fd_t: decouple udp4raw/udp4dg from each other. use udp4dg
and udp6 sockets in udpprobe primitive, rather than have each
udpprobe task create its own socket.
* scamper_fd_t: add methods that return an available open socket for
probing a given destination without blocking if another task is
probing the same destination. use this with ping -F 0 and trace -s 0,
instead of generating random port values, so that scamper opens
the minimum number of file descriptors.
* ping and trace: have -O dl mean to capture transmit and receive
timestamps from a datalink interface. add -O raw option so that
IPv4 TCP probes can be transmitted over a raw socket, to allow transmitted
TCP packets to be observed on the datalink interface.
* add memory-mapped ring buffer support (PACKET_RX_RING) for receiving
packets on datalink sockets on Linux. enable at scamper runtime
with -O ring. contributed by Alistair King.
## python module:
* generate module .c with Cython 0.29.37, to enable module to compile
with Python 3.11.
