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.

Installing splits into ASECs!
Sessions can now zero-copy data directly into pre-allocated ASEC
containers. Then at commit time, we compute the total size of the
final app, including any inherited APKs and unpacked libraries, and
resize the container in one step.
This supports both brand new ASEC installs and inheriting from
existing ASEC installs. To keep things simple, it currently requires
copying any inherited ASEC contents, but this could be optimized in
the future.
Expose new vold resize command, and allow read-write mounting of ASEC
containers. Move native library extraction into the installer flow,
since it needs to happen before ASEC is sealed. Move multiArch flag
into NativeLibraryHelper, instead of making everyone pass it
around. Migrate size calculation to shared location.
Separate "other" package name in public API, provide a path to a
storage device when relevant, and add more docs.

Don't double prompt on booting encrypted device
vold will store password securely until KeyGuard requests it
and hands it on to KeyStore.
This is a revision of
https://googleplex-android-review.git.corp.google.com/#/c/418123/
which was reverted. It had two bugs in LockSettingsService.checkVoldPassword.
1) We were not checking password for null, which caused an exception
2) checkPattern/checkPassword return true if there is no saved pattern or password.
This leads to situations where we get true returned even when the password
doesn't match. Call the correct one based on what is there, not what vold
thinks ought to be there.

Delegate mkdirs() to vold when lacking perms.
Apps without sdcard_r or sdcard_rw are still able to write to
their package-specific directory, but someone needs to first make
that directory on their behalf. This change will delegate the
mkdirs() call through to vold when an app fails to create directly.
MountService validates that the path belongs to the calling user, and
that it's actually on external storage, before passing to vold.
Update Environment to make app-vs-vold paths clearer.

Handle multi-user mountObb() requests.
Since emulated external storage paths differ based on execution
context, carefully fix up paths for various use-cases:
1. When sending paths to DefaultContainerService, always scope
OBB paths as belonging to USER_OWNER.
2. When sending paths to vold, always build emulated storage paths
visible to root.
3. Always use the original untouched path when talking with apps.
Mount OBB containers using shared app GID, so that an app can read
the mount point across users.
Handle legacy paths like "/sdcard" by resolving the canonical path
before sending to MountService. Move tests to servicestests, and
add tests for new path generation logic.

Include user identifier in external storage paths.
When building external storage paths, always include user in path
to enable cross-user paths and aid debugging.
Each Zygote process continues to only have access to the appropriate
user-specific emulated storage through bind mounts. A second set of
mounts continue supporting legacy /sdcard-style paths. For example,
a process running as owner has these mount points:
/storage/emulated_legacy
/storage/emulated_legacy/Android/obb
/storage/emulated/0
/storage/emulated/obb
Since Environment is created before Zygote forks, we need to update
its internal paths after each process launches.

Wait for ASECs to be scanned before proceeding
Move MountService up the list, then pause waiting for MountService to
finish scanning ASECs before the services that require those packages to
be ready.
Additionally, don't automatically mark all ASEC apps as FLAG_EXTERNAL on
reboot. This prevents AppWidgets and other things from being used with
ASECs which are on internal storage.

Allow forward locked apps to be in ASECs
We couldn't put forward-locked apps in ASEC containers before since we
didn't have any permissioned filesystems. This adds the ability for
forward-locked applications to be in ASEC containers.
This means that forward locked applications will be able to be on the SD
card now.
This change also removes the old type of forward-locking that placed
parts of apps in /data/app-private. Now all forward-locked applications
will be in ASEC containers.

Require device encryption password to perform adb backup/restore
This supersedes any backup-password that the user might supply. Per
design, the device encryption password is also always used to encrypt
the backup archive.
The CL introduces two new strings, used for prompting the user for
their device encryption password rather than their settings-defined
"backup password" when confirming a full backup or restore operation.

Revert encryption mapping for device wipes.
External storage volumes that were emulated+encrypted needed to have
their encryption mapping removed so that it doesn't try to encrypt the
volume after formatting them.
This just wires through an argument through vold, and assumes that vold
will do the right thing even if there is no encryption mapping set.
