Summary:                    [patch] multiparking, "WARNING[6006]: channel.c:2065
__ast_read: ..." fixed
Description: 
I had a look at the multiparking feature and did some tests. To be fair I
have to say that I tested multiparking with a patched version of 1.4.20.1 
http://bugs.digium.com/view.php?id=12740.
As the logic is the same in 1.6 trunk as in my patched version of 1.4 the
described failure also should occure in 1.6 trunk.

I always get this warning starting with the second call if core debug
level is set to 10:
>>>>>>
[May 29 10:40:44] WARNING[6006]: channel.c:2065 __ast_read: Exception flag
set on 'SIP/5555-081fddf0', but no exception handler
Really destroying SIP dialog '3c49a803c2b3-6bdvxzki22wa' Method: ACK
<<<<<<

Szenario:
 - Start asterisk.
 - A calls B (1st call).
 - B gets the call.
 - A parks B.
 - B hangs up, A hangs up.
 - A calls B (2nd call).
 - B gets the call.
 - A parks B.
  --> I get the warning described above!!

Logging output is included in attached file "logging.txt".

The problem is that filedescriptor sets nrfds and nefds in
main/features.c, do_parking_thread() aren't initialized to have zero bits
each time before the loop to call manage_parkinglot() is entered.
The attached patch
"asterisk-multiparking_initialize_filedescr_sets-0.0.1.patch" fixes this
bug.

Make sure the nrfds and nefds are reset to NULL
before we enter manage_parkinglot.
This will get rid of CLI warnings like:
__ast_read: Exception flag set on 'SIP/<NUMBER>-<ID>', but no exception
handler
