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.

Kevin P. Fleming 1ddc834b39 cleaup of the TCP/TLS socket API:
1) rename 'struct server_args' to 'struct ast_tcptls_session_args', to follow coding guidelines

2) make ast_make_file_from_fd() static and rename it to something that indicates what it really is for (again coding guidelines)

3) rename address variables inside 'struct ast_tcptls_session_args' to be more descriptive (dare i say it... coding guidelines)

4) change ast_tcptls_client_start() to use the new 'remote_address' field of the session args for the destination of the connection, and use the 'local_address' field to bind() the socket to the proper source address, if one is supplied

5) in chan_sip, ensure that we pass in the PP address we are bound to when creating outbound (client) connections, so that our connections will appear from the correct address

Tilghman Lesher c1351ad237 Merge realtime_update2 branch, which adds a new realtime API call named
'update2', which permits updates which match across multiple columns, instead
of requiring all tables to have a single unique identifier.  All of the other
API calls with the exception of 'update' already had the ability to match on
multiple fields, so it was a missing and very desireable feature that an API
call implementing an update should have this, too.

This does not change any outward performance of Asterisk, but it should make
life easier for application developers who use the RealTime framework.

Sean Bright 61664ec58b Make sure to compare the correct number of characters when special-casing
our DAHDI operator mode stuff.  Technically, it would work fine, as 'DAH'
is currently unique amongst our channel technologies, but as Jared points
out:

  <@jsmith> Sure... as long as the technology starts whith DAH.... but
            it could be DAHDOO!

Michiel van Baak 4560279c69 All ODBC parts can now use either unixodbc or iodbc.
This allows for the ODBC parts to work on OpenBSD as well.

99.99% of the work is done by seanbright (bow, bow) and I actually
did nothing but test and yell at him that it still didn't work :)

Thanks for helping out !

  Dialplan functions should not actually return 0, unless they have modified the
  workspace.  To signal an error (and no change to the workspace), -1 should be
  returned instead.

Mark Michelson b8aed684f5 This commit introduces a change to how the "joinempty"
and "leavewhenempty" options are configured in queues.conf.

Instead of using vague terms like "yes," "no," "loose," and
"strict," we now accept a comma-separated list of values
to determine when to consider a member available.

Extended details can be found in the queues.conf.sample
file. Note also that the above four referenced values are
still accepted for backwards-compatibility, but are mapped
internally to the new method of representing the option.

AST-105

Michiel van Baak 90751b16ca Merge the cli_cleanup branch.
This work is done by lmadsen, junky and mvanbaak
during AstriDevCon.

This is the second audit the CLI got, and
this time lmadsen made sure he had _ALL_ modules
loaded that have CLI commands in them.
