Release 2.1.0

Make multicast-group helpers and vsock fallback portable to QNX (#20)

* Make multicast-group helpers and vsock fallback portable to QNX

Two small portability fixes so this builds on QNX (and stays building
on macOS / BSDs):

  * UDPSocket::JoinMulticastGroup / LeaveMulticastGroup used the
    Linux-only struct ip_mreqn (with imr_ifindex).  Switch to the
    POSIX-portable struct ip_mreq.  Behaviour is unchanged on Linux:
    the previous code passed imr_ifindex = 0, which is equivalent to
    INADDR_ANY in ip_mreq.imr_interface.

  * The fallback definition of struct sockaddr_vm in sockets.h had a
    typo `_APPLE__` (single leading underscore).  This is harmless on
    Apple, where <sys/vsock.h> is used instead, but on a system that
    actually hits the fallback (e.g. QNX) a true `__APPLE__` macro
    would never have inserted svm_len.  Fix the spelling.
