Start MountService before performBootDexOpt

This change is to start Mountservice before starting
performBootDexOpt, as in one case, in performBootDexOpt
when system upgrade happens, StorageManager will be started to
get the low threshold of DataDir. But, at this point, as
Mountservice is still not up, StorageManager will end up
having a null object of Mountservice.

Be increasingly aggressive about fstrim if it isn't being run

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.

Properly recognize repeating wakeup alarms

cherry-pick from lmp-mr1-dev

The code in place was inappropriately treating all recurring alarms
as non-wakeup for purposes of deferral.  Worse, it was overriding the
"this deliverable batch of alarms includes a wakeup alarm" bookkeeping,
so could potentially cause inappropriate deferral of even standalone
wakeup alarms.

Tune delivery and batching of alarms

cherry-pick from lmp-mr1-dev

* Inexact alarms no longer coalesce with exact alarms.  The motivation here
is that exact alarms are far more likely to be wall-clock aligned, and in
general pulling all alarms toward wall-clock alignment is a bad idea.

* Wakeup times are now fuzzed within the target batch's allowed window
rather than being hard pinned at the start of the window.

Fix bad alarm delivery

The man bent over his hourglass,
A programmer of sorts. The day was green.

They said, "You have a blue hourglass,
You do not fire alarms when they're asked."

The man replied, "Alarms as they're asked
are changed within the blue hourglass."

And they said then, "But fire, you must
Alarms beyond us, yet themselves,

Alarms within the blue hourglass
That trigger exactly when they're asked."

Fix the delivery-fuzzing semantics that had been introduced in
81f9882b5aadd6a2289c9f521a06a7af5f35ebf0.  That patch turned out
to be incomplete; in particular, alarms scheduled later might require
the validity of an already-scheduled kernel alarm even if they did
not affect the head alarm batch directly, and this was not being
addressed.  For now, roll back the fuzzed delivery logic entirely.
(This is not a full revert because that patch also caused exact alarms
to be considered standalone for batching purposes, and we need to
preserve that new policy.)

This is a 'git revert' of 81f9882b5aadd6a2289c9f521a06a7af5f35ebf0
*except* that this CL preserves the "exact alarms are treated as
standalone" portion of the original patch.
