1. expose xwayland.Server's pid …

   wlroots wants to fork() and waitpid() on the result:
   
   https://gitlab.freedesktop.org/wlroots/wlroots/-/commit/871646d22522141c45db2c0bfa1528d595bb69df
   
   (this code *almost* does the right thing, but only does SIG_BLOCK in the
   first fork, not the parent...)
   
   applications using wlroots which have SIGCHLD handlers installed may
   interfere with this, so expose the server pid so they can use WNOWAIT
   trickery to avoid reaping this pid, to allow wlroots to do so.
   
   Maybe this is the wrong patch to fix the described issue: maybe pywayland
   should block SIGCHLD (via signal.pthread_sigmask(), since applications may
   be multithreaded, especially if they use asyncio) and then do
   wlr_xwayland_server_create(), then unblock it for users? But either way,
   seems like people might want to see the pid here.
