Summary:                    [patch] Directed pickup : picker picks own channel
instead of called party's channel
Description: 
When trying to pickup an extension, Asterisk does not identify the correct
channel. The error messages are (picker being 53, called party 52) :

chan_sip.c: Trying to pick up 52 at default
channel.c: Can't masquerade channel 'SIP/53-0a273e48' into itself!
app_directed_pickup.c: Unable to masquerade 'SIP/53-0a273e48' into
'SIP/53-0a273e48'app_directed_pickup.c: No target channel found for 52

It appears that the function pickup_by_exten does not check that the
channel it has found is not its own. The included patch seems to correct
that behaviour.
