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.)

Bug 18765436
This is a 'git revert' of 81f9882b5aadd6a2289c9f521a06a7af5f35ebf0
*except* that this CL preserves the "exact alarms are treated as
standalone" portion of the original patch.

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.

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.

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.

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.

ProxyInfo.getPacFileUrl() can not be null. It will be equal to
Uri.EMPTY. Checking for null was causing global proxies to never be
disabled. Or more accurately, global proxies would be disabled, but
would reappear after a reboot.
ProxyInfo.getExclusionListByString() can be null. If no
exclusion list was specified, the proxy settings would not be
successfully saved, they would disappear after reboot.

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.

Ensure that the callback always sees the current-operation state in sync
with the various other bits of internal backup-operation state. Previously
only the current-operation state was managed inside the critical section;
this resulted in a slim race window where a callback could see an ongoing
operation as still valid, but after the internal state on which that
operation depended had already been cleared.

An app can send an accessibility event by calling the send methods
on view or directly asking the accessibility manager to do that.
While the recommened way to send such events is calling the methods
on view a legacy app or app whose developer did not read the docs
carefully may be calling the accessibility manager APIs directly.
In such a case the event does not have assigned window id and does
not get send. Since events fired by using the accessibility manager
directly lack context to determine whether thier source is important
for accessibility we assume they come from an important view to
avoid breaking backwards compatibility.

The restore-session idle timeout should not be ticking while we're
doing legitimate restore work. We now explicitly stop the timeout
ticker [a delayed message on our handler thread] whenever we undertake
a valid restore operation. The timer is already correctly resumed
when restore operations conclude.
(In practice we need to suspend the timeout tracking at exactly those
times when we're entering the wakelock-protected restore flow. The
timeout is reestablished when the wakelock is released; this part
is already in the code.)

Some of the admin policies are throwing security exceptions in
a managed profile without being documented correctly and others
shouldn't be throwing security exceptions.
Changed setCameraDisabled() to not throw an exception. It now just
prevents work profile apps from using the camera.
Changed wipeData() to allow passing in ERASE_EXTERNAL_STORAGE. In
secondary users/profiles, this is just going to remove the user, so
the flag is harmless.
Updated documentation for setKeyguardDisabledFeatures() and resetPassword()
to indicate that they cannot be called in a managed profile.

This is needed to allow the always-on VPN to survive network
switches. In L, network switches are graceful, and in order to
switch to a network, the system first has to validate it using
DNS requests (from netd, running as root) and HTTP requests
(from NetworkMonitor, running inside the system_server).
This should also allow always-on VPN to work on networks like
T-Mobile that use 464xlat, fixing a bug that has been present
since K.

Currently, the lockdown VPN adds firewall allow rules matching
the whole subnet that the server assigned, so for example if
the VPN server assigns it the IP address 10.1.23.5/8, it will
allow the whole of 10.0.0.0/8 to pass the firewall.
This is needlessly overbroad and has a particularly bad corner
case where if the prefix length is 0, everything is allowed.
