Add two apis for one touch record.

This change introduces new two apis for one touch record.
1. setRecordRequestListener
 It's used to get notified when a recorder device initiates
 "one touch record". As return of callback, client should
 generate "record source" and return it.
2. startRecord
 It's used to initiate "one touch record" from Tv.

Along with this, add HdmiRecordSources which is a helper
class assisting buidling byte array form from the given
record source information.
