[PATCH libxtrans xserver v2 0/5] systemd socket activation code for xserver

[Łukasz Stelmach]

Hi All.

I've fixed the problems reported for the previous release and those I had found myself.

Let me describe each patch.

1. Add const qualifier to unix_nolisten.

   Without const I got a warning and tcp_nolisten is marked as const too.

2. Define TRANS_RECEIVED flag for transports

   The patch defines a new flag to mark transports related to sockets
   received from systemd. The next patch uses it to omit the marked
   transports in the "for" loop and do not create sockets for them. I
   chose not to use TRANS_NOLISTEN because it affects other parts of
   code too.

3. Enable systemd socket activation

   The main patch. It enables libxtrans to "catch" and reopen
   file descriptors received from systemd via its socket passing
   interface. With this patch applied and systemd properly configured,
   it is possible to:

   + start an X server on demand, when the first connection from a client
     comes in,

   + start X clients before an X server is fully functional.

4. configure.ac: enable systemd socket activation in libxtrans

   Modify configure.ac to:

   + add -DHAVE_SYSTEMD to CFLAGS to enable the socket activation code
     from libxtrans, and

   + libsystemd-daemon in LDFLAGS.

5. Do not define ErrorF in xstrans.c, libxtrans handles it.

   Yet another cleanup due to warning message.
