This commit fixes primarily a race condition that occurs when xinit(1) shuts
down: by not acting properly fluxbox gets caught in an infinite loop. It
caused bug #1100.
xinit(1) sends a SIGHUP signal to all processes. fluxbox tries to shutdown
itself properly by shutting down workspaces and screens. While doing that, the
Xserver might be gone already. Additionally, fluxbox used to restart() itself
on SIGHUP, which is clearly not the right thing to do when xinit(1) is about
to end the session.
So, fluxbox does this:
* handling SIGHUP now shuts down fluxbox without clearing workspaces and
screens.
* A 2 second alarm() is triggered in Fluxbox::shutdown() as a last resort
* XSetIOErrorHandler() is used to recognize the disconnect from the xserver.
* SIGUSR1 is for restarting fluxbox, SIGUSR2 for reloading the config
* FbTk/SignalHandler.cc/hh is gone; this unused abstraction served currently
no real purpose. Signal handling is now done in main.cc
* Unrelated to the issue itself src/main.cc was trimmed down quite a bit and
the code (responsible for handling the command line interface) was moved to
src/cli*
This patch took copy of config.rpath from gettext 0.18.2 to build-aux/
directory. Software projects usually does not need to do that, because
the file is copied by gettext autopoint in autogen.sh or bootstrap.
In Fluxbox case calling autopoint seems wrong, as it would generate po/
directory with necessary make automation, adn 'msgid' & 'msgstr' files,
but that is not how the translations are done in this project.
This commit alters XRANDR (X Resize And Rotate) extension dependency,
which is expected to have at least version 1.4. Earlier old versions of
xrandr were supported, at least to some extent.
It seems autoheader version 2.69 does not work with configure.in file,
and AM_CONFIG_HEADER macro.
