c517bc1502 Once in a month, when the moon is full, killall mistakenly considers 
living process as a zombie and refuses to kill it. The cause is that
the code masks ki_stat with SZOMB to compare with SZOMB, but ki_stat
is not a mask.

Free can properly handle NULL pointer (but keep free() call on the premise
that the code might be reused).

de55508483 Simplify various code that allowed for sys_signame being lower case. 
This was changed in r218285.

12dacf622b Make sys_signame upper case. 
This matches the constants from <signal.h> with 'SIG' removed, which POSIX
requires kill and trap to accept and 'kill -l' to write.

'kill -l', 'trap', 'trap -l' output is now upper case.

In Turkish locales, signal names with an upper case 'I' are now accepted,
while signal names with a lower case 'i' are no longer accepted, and the
output of 'killall -l' now contains proper capital 'I' without dot instead
of a dotted capital 'I'.

73d0971bf2 Add support for the arbitrary named jail parameters used by jail_set(2) 
and jail_get(2).  Jail(8) can now create jails using a "name=value"
format instead of just specifying a limited set of fixed parameters; it
can also modify parameters of existing jails.  Jls(8) can display all
parameters of jails, or a specified set of parameters.  The available
parameters are gathered from the kernel, and not hard-coded into these
programs.

Small patches on killall(1) and jexec(8) to support jail names with
jail_get(2).

avoids "No such process" warnings when killing threaded processes.

killall stopped after failing to kill one process or whether it kept
going.

69179c1439 Work around the p_comm[] size limit. If the user supplies more than 
16 characters, only check the first 16 since that is all the kernel
records.  This isn't ideal, but it is probably the best we can do.
Otherwise, "killall communicator-linux-4.76.bin" will not match
the process as the kernel only records "communicator-lin".

8750ed5f77 After positive feedback from a few folks, activate a switchover to 
using killall.c instead of the perl version that depends on procfs.
The C version uses sysctl().  The program is based on a hack that was
originally written about 6 years ago and has evolved somewhat since then.
(which is why it is a superset of killall.pl, rather than being a clone.)

1198f21caf killall.c is meant to be a superset replacement of killall.pl, the 
main difference is that it uses sysctl to get the process lists rather
than /proc - thereby reducing the dependency on /proc by one more tool.
