Modified UI for Emergency Callback Mode
Specific list of changes that are needed for the support of CDMA emergency
callback mode:
1. Removed Teleca's implementation of the ECM UI - it had limited functionality
2. Added service that inserts ongoing ECM notification in the status bar and updates countdown
info in the notification in 1sec intervals when phone enters ECM.
3. Added dialog box prompting to exit ECM when any application wants to prompt a user to exit
ECM or a user selects ongoing ECM notification. It responds to
ACTION_SHOW_NOTICE_ECM_BLOCK_OTHERS intent.
