Summary:                    AGI-program receives SIGHUP on hangup although
AGISIGHUP is set to "no"
Description: 
I added a LOG_WARNING message to res_agi.c:

if (needhup) {
	needhup = 0;
	dead = 1;
	if (pid > -1) {
                ast_log(LOG_WARNING, "this is executed\n");
		kill(pid, SIGHUP);
	} else if (agi->fast) {
		send(agi->ctrl, "HANGUP\n", 7, MSG_OOB);
	}
}

I have this AGI-program:

#include <stdio.h>
int main(int argc, char *argv[])
{
        int i;
        for (i=0; i<50; i++) {
                fprintf(stderr, "message %d\n", i);
                sleep(1);
        }
        return 0;
}

I call it and hangup while it is writing the messages to the CLI. This is
written to the CLI:

*CLI>   == Using SIP RTP CoS mark 5
    -- Executing [69 at default:1] Answer("SIP/222-0822f9c0", "") in new
stack
    -- Executing [69 at default:2] Set("SIP/222-0822f9c0", "AGISIGHUP="no"")
in new stack
    -- Executing [69 at default:3] AGI("SIP/222-0822f9c0", "test") in new
stack
    -- Launched AGI Script /var/lib/asterisk/agi-bin/test
message 0
message 1
[Oct 16 00:18:09] WARNING[7980]: res_agi.c:2639 run_agi: this is executed
    -- <SIP/222-0822f9c0>AGI Script test completed, returning -1

*CLI> 

Obviously the AGI-program receives SIGHUP when I hangup. But because
AGISIGHUP is set to "no" the AGI-program should not reveice that signal
according to the documentation (core show application agi).

Tested version is Asterisk 1.6.0.1.

Always use the value of the AGISIGHUP when running an AGI.

Prior to this patch, the value of AGISIGUP was not always
honored when set on a channel.
