Change ConnectivityService to use a factory when creating
NetworkStateTrackers, which gives us a good place to inject mocks
for testing. Add initial tests to verify that network routes are
added and removed as networks changed.

Wrote initial suite of tests for ThrottleService, checking a variety
of edge cases. Checks going over limits, updating policies, and reset
after cycle elapses.
Moved NTP code in ThrottleService into new TrustedTime interface,
which makes it easier to understand, and allows tests to provide custom
clocks.

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
