To make it easier to support disk formats created using old versions
of dm-default-key with new kernels, choose the disk format to use
based on options_format_version and first_api_version properties
instead of checking the version number of the kernel module.

In EmulatedVolume#doMount, if some operations fail, we call
EmulatedVolume#doUnmount.
During this unmount we try to unmount Android/ causing a FUSE_LOOKUP
on the FUSE mount. If the FUSE mount is not up, this can hang.
Now we introduce a new state to prevent unmounting Android/ if it
wasn't mounted.

Previously every directory on external storage had project ID quota
inheritance enabled; this means that if any new file/directory is
created under such a directory, it will inherit the project ID from the
parent. We use a default project ID of 1000 for generic directories, and
application-specific project IDs for app-specific directories.
MediaProvider is responsible for updating the quota type in the generic
directories, as it scans all files there. However, there is a problem
with this approach: if you move a file to a directory with project ID
inheritance set, and the project ID of that file differs from the
project ID of the dir, that results in an EXDEV error, and requires a
copy instead. For example, if /sdcard/DCIM/test.jpg has a project ID of
1003 (for images), and you try to move it to /sdcard/Pictures/test.jpg,
that would require a copy, because the project ID of /sdcard/Pictures is
1000.
While this is not a very common scenario, it's still better to avoid it.
Luckily we can - since MediaProvider anyway scans all files, it will set
the project ID on individual files correctly - there's no need to
inherit them.
We then only need to inherit quota in application-specific directories,
since in those directories the app can create files itself, and those
need to be tagged correctly.
This change enables that, by removing quota inheritance setting from the
top-level directory, and instead doing it for app-specific directories
instead.

During userspace reboot /data might be unmounted & remounted, meaning
that CE keys stored in fs-level keyring will be lost. In order to be
able to restore them, when installing new key to fs-level keyring, it's
also added to session-level keyring with type "fscrypt-provisioning".
Then when init_user0 is called during userspace reboot, vold will try to
load CE keys from the session-level keyring back into fs-level keyring
for all the users that were unlocked before the reboot.
If for any user vold fails to install the key, init_user0 will fail and
fallback to hard reboot will be triggered.

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.
