The magic trick to avoid this crash is not to
try to find the channel by name in the list,
which is slow and resource consuming, but rather
to pay attention to the result codes from the
ast_bridge_call, to which I added the 
AST_PBX_NO_HANGUP_PEER_PARKED value, which
now are returned when a channel is parked.
Why? because CDR's aren't generated via parking,
so nothing is needed, but if a transfer occurred,
there are critical things I need.

If you get AST_PBX_KEEPALIVE,
then don't touch the channel pointer.

If you get AST_PBX_NO_HANGUP_PEER, or
AST_PBX_NO_HANGUP_PEER_PARKED, then don't
touch the peer pointer.

Updated the several places where the results
from a bridge were not being properly obeyed,
and fixed some code I had introduced so that
the results of the bridge were not overridden 
(in trunk).

All the places that previously tested for 
AST_PBX_NO_HANGUP_PEER now have to check for
both AST_PBX_NO_HANGUP_PEER and AST_PBX_NO_HANGUP_PEER_PARKED.

I tested this against the 4 common parking
scenarios:


1. A calls B; B answers; A parks B; B hangs up while A is getting the parking
slot announcement, immediately after being put on hold.

2. A calls B; B answers; A parks B; B hangs up after A has been hung up, but
before the park times out.

3. A calls B; B answers; B parks A; A hangs up while B is getting the parking slot announcement, immediately after being put on hold.

4. A calls B; B answers; B parks A; A hangs up after B has been hung up, but before the park times out.


No crash.

I also ran the scenarios above against valgrind, and accesses looked good.

a. Parking will cause ast_bridge_call to return
either AST_PBX_NO_HANGUP_PEER or AST_PBX_NO_HANGUP_PEER_PARKED;
in the latter case, peer is (most likely) a bad
pointer, you can no longer deref it. If it does still
exist, it is under another's thread control, and
could be destroyed at any time.
b. The same applies to AST_PBX_KEEPALIVE, in which
case, the chan ptr cannot be used, as another thread
owns it and may have destroyed the channel.
c. In the former case, you need to check peer to see if it
still exists before you deref it, and obtain a lock.
d. In neither case should you do an ast_hangup(peer).
e. Do not overwrite the result code from ast_bridge_call.
