Proper supplementary service notification handling (1/5).

and replace it by well-defined call properties.

Creating connections for conference event package participants.

- Add "addExistingConnection" method to connection service which provides
a way for a connection service to notify telecom of a pre-existing
connection (connections are normally created through telecom).
- Modify TelephonyConferenceController to retrieve its state from a
multiparty connection in the conference (in the case of IMS calls, this
would be the ImsCall that manages the conference) instead of just taking
the first one.

Add functions to update on conference changes.

+ Add onConferenceChanged() to Connection, so that the Connection can
make act on changes to the conference.
+ Add a utility function to PhoneCapabilities to remove a capability
from a PhoneCapabilities bitmask. Figure this abstracts some bit
logic away to make things more readable.

Support disconnecting conference participants from conference.

- Added "onDisconnectConferenceParticipant" method used to inform a
connection acting as the conference host that one of the participants
should be disconnected.
- Added "VIRTUAL_CALL" PhoneCapability used to indicate that a call cannot
be the active or background call, but only be a child of another call.

Replace onConferenceChanged with onConnectionAdded.

This change is motivated by a desire to be able to adjust the
phone capabilities of a conference depending on its connections.

Turns out Connection is not a good place to do this, because when
the conference is set, this code is only fired if the connection
service already contains the conference. Conference makes more
sense to do this anyways, at the end of the day.

+ Add onConnectionAdded function to Conference.java.
- Remove onConferenceChanged function from Connection.java.

Conference event package performance improvement.

- Instead of sending each participant to the telephony conference
controller, all participants are sent at once.  This way the conference
only needs to be recalculated once.

Add telephony.DisconnectCause for merged IMS call.

When merged, IMS calls are consolidated into one call. Thus they
"disconnect", even though the user can continue to comminucate
with the party on that call.

We want to recognize this scenario so we can control relevant
behaviors (ie.don't play the "end call" tone in this case).

Change Connections to allow setting conferenceable with conferences.

- Added IConferenceable interface used so that connections and conferences
can both be considered candidates as "conferenceable" with a connection.
- Fixed ConnectionService#conference to support cases where either call 1
or call 2 is a conference and the other is a connection.  Previously did
not support cases where call 2 is a conference.

telecomm: Re-add original ParcelableConnection constructor

 * We changed this for the supplementary service notification feature,
   but some proprietary code has a bunch of dependencies on it.
 * Just add the original constructor and set the new field to zero so
   that the proprietary IMS stack doesn't need changing too.
