Browse Source 
* 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.

* link against libpython
* have all time parameters take either a timedelta or float/int. float/int
parameters are all seconds.
* add ScamperInstError exception which identifies the scamper instance
and includes the error string returned by the instance.
* reduce copying in methods that return bytes objects
* add str method for ScamperInst
- reenable python build
