Another try to get the signal/dead child recovery stuff right.
Could the brave signal crew (TM) (Austin, Garry, Raphael, Tim)
please do bad tests to the new code? I removed all strange
constants (SA_NODEFER etc.) and used only glib and POSIX stuff.
* app/main.c
* libgimp/gimp.c:
- Call gimp_signal_private() with no flags to enforce a proper
sigaction() behaviour (block signals while handler is active).
- Removed the reentrancy guards from the handlers.
- Renamed the handlers.
- Ignore SIGPIPE in the app and in plugins.
- Re-introduced the SIGCHLD handler because it should work
now. Also added a SIGCHLD handler to libgimp/gimp.c.
* app/errors.c
* libgimp/gimp.c: in the signal handler, unblock all signals
with sigprocmask() before calling g_on_error_query() because
gdb otherwise inherits the blocked signals and does nothing.
Wrapped the statements with "if (TRUE) { }" blocks so it's
easy to make the stack trace a command line option.
* app/plug_in.c
* libgimp/gimp.c: listen for G_IO_ERR and G_IO_HUP on the read
channels. In the app, pop up an error message and clean up the
plugin. In plugins, clean up and exit.
* libgimp/gimpwire.c: removed the "plug-in chrashed?" message
and print the program's name with all error messages.
* plug-ins/helpbrowser/helpbrowser.c: typo.
