Refactor: Make SendMessage async 

This commit does two things.  First it makes SendMessage an async
method, which returns only when the SMS message has been successfully
sent or failed.

This also adds a set number of tries that oFono will resubmit the PDU to
the SMSC.  If any fragment fails to be submitted, the entire send
message attempt is deemed a failure and an error is returned to the caller.
