The current heuristics depend on devices being alive at midnight+ in
order to run periodic background fstrim operations. This unfortunately
means that people who routinely turn their devices off overnight wind
up with their devices *never* running fstrim, and this causes major
performance and disk-life problems.
We now backstop this very-friendly schedule with an increasingly
aggressive one. If the device goes a defined time without a background
fstrim, we then force the fstrim at the next reboot. Once the
device hits the midnight+ idle fstrim request time, then we already
aggressively attempt to fstrim at the first available moment
thereafter, even if it's days/weeks later without a reboot.
'Available' here means charging + device idle. If the device never
becomes idle then we can't do much without rendering an in-use device
inoperable for some number of minutes -- but we have no evidence of
devices ever failing to run fstrim due to this usage pattern.
A new Settings.Global element (type 'long', called
"fstrim_mandatory_interval") is the source of the backstop time. If
this element is zero or negative, no mandatory boot-time fstrim will
ever be performed. If the element is not supplied on a given device,
the default backstop is 3 days.
Adds a new string to display in the upgrading dialog when doing
the fstrim. Note it is too late for this to be localized, but since
this operation can take a long time it is probably better to have
it show *something* even if not localized, rather than just sit there.

If the lock screen is not shown, then let activities keep running
while dozing. This is important to support ambient mode on watches
since it allows the home app to keep running.
To make this possible, we need to inform the activity manager about
the exact wakefulness state, not just the overall boolean
interactive state.

TimePickerSpinnerDelegate doesn't need to deal with input when running
inside LayoutLib. So, we just return the keycodes as if it's running in
English locale.

There was a window of time in Lollipop where we persisted certificates
after they had passed through a decode/encode cycle. The well-written
OpenSSL library was liberal when decoding (allowing slightly malformed
certs to be parsed), but then strict when encoding, giving us
different bytes for effectively the same certificate.
A related libcore change (0c990ab4a90b8a5492a67b2b728ac9a4a1ccfa1b)
now returns the original bytes verbatim, fixing both pre-Lollipop
installs and installs after that change.
This change recovers any apps that had been installed during the
window of time described above by doing a one-time check to see if
the certs are effectively equal.

Bug: 18289984
If Surface:finalize() happens after HwuiContext:finalize()
it would try to manipulate a destroyed object. However, as
Surface:finalize() always calls HwuiContext:destroy() this
can be fixed by simply getting rid of HwuiContext's finalizer

When PowerManager.boostScreenBrightness() is called, the screen
brightness is set to maximum for 5 seconds. This action is
also considered to be user activity.

The choice of Action Bar layout depends on the theme. This also affects

This enables a change in Settings that allows device
encryption to be disabled by the user.

Updating the accessibility layer behavior to reflect the new
model where accessibility no longer overrides strong encryption.
Now enabling an accessibility service lowers the encryption
level but the user can bump it up in settings if desired.
