VoicemailStatus content provider implementation.

- New Voicemail.Delegate implementation for voicemail_status table.
- modified openFile() interface to simplify the interaction.
- UridData now has a getWhereClause() method that can be used by both
  the tables to set selection clause based on the uriData.
- Imrpoved permission checks for ContentValues for
  update/insert/bulkinsert operations.
