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.

All but a few lines of this is for issue #16013164, which allowed
apps to do some operations as the media uid by having it call
back to them to open a file. The problem here is with the tempory
identity stuff in the activity manager, allowing us to make the open
call as the original caller... ideally we should figure out a way
to just get rid of all of that, but the solution here is actually
easier (even though it doesn't look it) -- we now hand a token over
to the openFile() call that it can use when doing permission checks
to say "yes I would like the check to be against whoever is responsible
for the open". This allows us to do the uid remapping for only this
one specific set of permission checks, and nothing else.
Also fix issue #17487348: Isolated services can access system services
they shouldn't be able to. Don't send any system service IBinder objects
down for the first initialization of an isolated process.

We migrated to pure XT stats a long time ago, so we no longer need
to keep the DEV stats cached in RAM. This saves ~250KB on a typical
device.

Added a new SLEEP_TIMEOUT setting which governs how long the device will
remain awake or dreaming without user activity. By default this
value is set to -1 which maintains today's existing behavior.
We basically represent the time we are allowed to be dreaming as a new
kind of user activity summary state called DREAM, similar to BRIGHT
and DIM. When the sleep timeout expires, the state is cleared and
the dream ends.
