Remove MMS from the framework

The MMS code has been moved into the mms-common library.
Move SqliteWrapper (and make it hidden) into the database
directory because Telephony.java depends on it. Create a mmscommon
library similar to androidcommon for a number of files used both
by the telephony layer, by mms, and by myfaves.
