[PATCH v3 0/9] replace signal() with sigaction()

[Jeremiah Mahler <jmmahler@gmail.com>]

This is version 3 of the patch set to convert signal(2) to sigaction(2)
(previous discussion [1]).

[1]: http://marc.info/?l=git&m=140148352416926&w=2

Changes in this revision include:

  - Using NULL pointers instead of 0 as per the
    Documentation/CodingGuidlines pointed out by Chris Packham.

    sigaction(SIGCHLD, &sa, NULL);

  - Conversion of all remaining files which used signal().

  - sigchain.c required the most changes.  Both the old signal handler
    was used and the return value from signal() was being checked.
    signal() would return the previous error handler which would be
    SIG_ERR if an error occurred.  sigaction() just returns -1 in this
    case.
