testApfFilterRa is failing with probabiliy 1/10 ~ 1/15 on the following
assert: assertDrop(program, packet, lifetime/6), for lifetime values
that are multiple of 6, where 6 is the hardcoded fraction of RA lifetime
to filter in ApfFilter.java.
When the lifetime is not a multiple of 6, the remainder of 1 to 5
seconds gives enough margin so that when the APF program is simulated
the faked lifetime of the program is less than lifetime/6 away and the
packet is dropped.
However for lifetimes which are exact multiples of 6, this margin is
always 0s and that result in nondeterminism in the result. This is
consistent with the obervation that the only failed assert was for a
lifetime of 300s, the only multiple of 6.
This can be observed by detecting the age limit at which the filter
stops dropping packet oscillating between lifetime/6 and lifetime/6 + 1
for lifetimes which are multiple of 6.
This patch fixes the flakyness by freezing the flow of time in tests so
that the expected filter age threshold is consistent and stable.
Test: no failure observed in 1000 runs.

Couple unit tests are failing due to conditional statements
not enclosed in the parenthesis, which causes unexpected
returned value for the equals function. So fix it.

Broadcasts are not sent until BOOT_COMPLETED is received.
When the device boots with usb plugged, the UPDATE_STATE
for connted and configured would be received way before
BOOT_COMPLETED is received. Since, devices can continue
to stay in same usb configuration(set through persistent
property trigger), check and send a usb state broadcast
if needed.
BUG: 34451258
Test: Manually checked to verify the broadcasts sent.

This prevents cases where the device starts up and attempts
to change the config, but intents cannot yet be sent.
A patch to resend this skipped intent is necessary to
finish fixing the bug.

Test: Check that usb state is properly handled on boot

Callbacks are possible even if no listener was defined.
Perform a check and print error (as opposed to crashing).

Method to tell when the adapter finished (or will finish) being in
discovery mode.
Test: compiles and still can scan
