Christopher Kohlhoff d6cad8835e Expose sigaction() flags via optional argument to signal_set::add.

When registering a signal, it is now possible to pass flags that specify
the behaviour associated with the signal. These flags are specified as
an enum type in a new class, signal_set_base, and are passed to the
underlying sigaction() call. For example:

  asio::signal_set sigs(my_io_context);
  sigs.add(SIGINT, asio::signal_set::flags::restart);

Specifying flags other than flags::dont_care will fail unless
sigaction() is supported by the target operating system. Since signal
registration is global, conflicting flags (multiple registrations that
pass differing flags other than flags::dont_care) will also result in
an error.
