Don't call IKeystoreMaintenance::earlyBootEnded() too early on FDE
devices, so that keystore2 doesn't have to be restarted.
Bug: 192090857
Test: Tested FDE on Cuttlefish, both first and non-first boots.
Verified via log that earlyBootEnded is now called only when it
should be, and that keystore2 no longer has to be restarted.

Now that vold uses Keystore2 rather than the Keymaster HAL directly, and
also the new version of Keymaster is called "KeyMint" instead, replace
most of the references to Keymaster in vold with Keystore.
(I decided not to include the "2" in most places, as it seemed
unnecessarily precise in most places, and it would be something that
might need to keep being updated. Only Keystore.{cpp,h} really need to
care about the version number.)
I didn't rename many things in cryptfs.cpp, as that file will be going
away soon anyway. I also left "wait_for_keymaster" and "vdc keymaster
earlyBootEnded" as-is for now, as those are referenced outside vold.

HardwareAuthTokens are no longer used by vold since Android P. So remove
the auth token parameter from vold. This patch doesn't remove the token
from IVold.aidl, and the methods in VoldNativeService.cpp return an
error if a non-empty auth token is passed to them.

With this change, vold exposes an API that may be used to bind key
storage encryption keys to a given seed value. The seed value passed to
vold must be consistent across reboots, or key storage keys will not be
derived consistently. The seed is expected to be set very early in boot,
prior to the use of any key storage encryption keys.
This feature is intended to be used for embedded applications such as
in autos, where the seed may be provided by some other component of the
system. In such systems, there is a default user that is automatically
signed in without a PIN or other credentials. By binding the file
encryption to a platform-provided seed, the default user's data gains
additional protection against removal of the Android embedded device
from the integrated system.
Bug: 157501579
Test: Set seed at startup via init.rc. Seed changes fail as expected.

destroyDsuMetadataKey() / destroy_dsu_metadata_key() calls
android::gsi::GetDsuMetadataKeyDir() to query the DSU metadata
encryption key dir and destroy the key.
This releases the resource and allows consecutive DSU installations to

This can be used to fixup application directories in case they have been
created by some other entity besides vold; the main use case for this
API right now is OBB directories, which can be created by installers
outside of vold; on devices without sdcardfs, such directories and the
files contained therein are not setup correctly. This API will make sure
everything is setup the way it needs to be setup.

StubVolume is a volume type for ARC++ external storage. Named StubVolume
because it is managed from outside Android (not through Android kernel).
Previously, StubVolume is a diskless volume. However, as mentioned in
jsharkey@ email, a disk is needed for StubVolume to hold "kInternal"
(external storage type that is "external" from Android perspective,
but is "internal" to the device. For example shared directory from
ChromeOS to Android) and "kIndexable" (whether or not a disk should be
indexed by MediaStore).
The addition of disk means we could expose the createStubVolume API to
add a disk flags, which is also introduced in this CL.
Both kInternal and kIndexable will be introduced in separate CL.

vold historically offerred functionality to create directories on behalf
of others. This functionality was purely used to create app-specific
data/obb/media dirs. Make this more explicit by renaming the method to
indicate this.
Additionally, in the past, we never needed to care about the UID set on
these directories, because sdcardfs would take care of that for us
automatically. But with sdcardfs going away, we need to make sure the
UID of the app-specific directories is set correctly. Allow the caller
to pass this in as an argument.

Mounting a FUSE path needs two steps:
1. Mounting the filesystem
2. Starting the FUSE session in the FUSE daemon
The second part requires retriving an fd from (1) and the mount paths
and passing it to the FUSE daemon.
Previously, we'd return from the Vold mount call and mark the volume
as mounted while we scramble to do (2). This means there's a time
period where the Volume is marked as MOUNTED but not actually ready
and any IO access on the paths will hang forever. This could also be
misleading when interpreting bug reports.
Now, we block the Vold mount call until the FUSE session is started
