Details:

The files siglist.c and sighandlers.cc are incomplete as far as a list of
signals SIGxxxxxxx that could appear in the Unix/Linux header file signals.h
(or bits/signum.h).  For example, typing the following commands:


s = SIG;
f = fieldnames(s);
n = struct2cell(s);
[sn, in] = sort(cell2mat(n));
f(in)
n(in)


will produce a list of signals that doesn't quite match what is inside the
signum.h header file on my system.  These are missing:


#define SIGKILL     9   /* Kill, unblockable (POSIX).  */
#define SIGSTKFLT   16  /* Stack fault.  */
#define SIGUNUSED   31


So the attached changeset adds a few of these signals so that the SIG function
(and the sorting above) produces the same list that appears in my signum.h. 
However, this is not a complete list for everyone's system as there are more
entries listed here:

for example, and still more obscure ones floating about some of which already
appear in siglist.c and/or sighandlers.cc.
