This is the framework part, moving classes around so the framework
no longer needs to link to android-common. Makes some APIs public,
others that didn't need to be public are private in the framework,
some small things are copied.
Most of these are file moves; a couple notable exceptions are the changes due to the move, and fixing up test code:
- database/DatabaseCursorTest.java
- database/DatabaseStatementTest.java
- net/UriTest.java
