[easytag/wip/easytag-next: 2/4] Use sigaction() rather than signal()

[David King <davidk src gnome org>]

commit 2beef8aaf76fcfb7e341b8d4de94c8be0febdc93

    Use sigaction() rather than signal()
    
    Use of signal() is discouraged, as some really old systems have signal
    handlers which return int, not void.
