Collapse common packages (1/?)

Move the majority of packages out of common. When trying to move
common.activity to activities every file switched from a rename to
separated deletes and adds. Will move tests and the rest of common
in a separate CL.

Test: Built GoogleContacts, Contacts, GoogleContactsTests,
ContactsTests.
