In order to create a DisconnectCause with a label/description that does
not require specifying a tone.

+ Add a hidden "UNKNOWN" default type to ToneGenerator.
- Hide the Telephony DisconnectCause from the public API.
+ Add a Telecomm DisconnectCause. This is parcelable, and contains
information (code, user facing message, non-user facing reason,
and tone) to help describe the disconnect state and what behaviors
an application can implement for the user experience. This reduces
the causes for a disconnect to a more generic set.
+ Lots of work to pipe this through. DisconnectCause replaces the
code and message which were formerly passed around.
