* Save mount options and fstype for DiskPartition objects
* Pass mount options and fstype to PublicVolume ctor
* Pass mount options to ext4::Mount/f2fs:Mount
* Use specified/default fstype if blkid fails
This is trivially extensible for other fs types.

* Fsck was hitting a neverallow on public volumes not formatted in vfat
because it was always using the trusted context
* Always run trusted fsck for private volumes and untrusted for public

Fix random failures while running CtsAppSecurityHostTestCases with
adoptable storage due to a format failure. The crypto_blkdev node
might not be immediately available after create sometimes. Adding
a wait in create to make sure the node is available.

We previously only set +F for /data/media, but adopted storage needs
this as well. Instead we add support for adding attrs to PrepareDir.

When the vold core decides if a device is SD or USB, it checks for MMC
or virtio, however when the filesystem type is decided, it does not
check for virtio, only MMC. This causes virtio SD cards to be formatted
with ext4 unconditionally.
This fix is independently correct, but it incidentally gets adopted
storage working on cuttlefish (and Android Emulator) because f2fs can
support fscrypt and casefolding at the same time; ext4 currently cannot.

When we're mounting a private volume, we create stacked emulated volumes
on top of it. Due to the ordering there, we would broadcast the emulated
volumes being created *before* the "mounted" status update. This in turn
could cause us to try and mount these emulated volumes before the
underlying private volume is really mounted. This is problematic in
particular on devices that support a filesystem keyring, where we need
to do some additional setup before the devices can be used.
While we could modify StorageManagerService to delay the mount, a safer
fix at this stage of the release is to just fix the ordering of these
events. To achieve that, add a simple postMount() helper, that is called
after a succesful mount. This allows us to setup the volume properly
before trying to mount any stacked volumes.

The dm-crypt solution requires a kernel patch that won't be present in
the GKI kernel, while the new metadata encryption system in the GKI
kernel solves this problem in a much cleaner way.
Test: create private volume on Cuttlefish, setting property both ways.

For some reason this can be racy; until we understand the root cause,
retry to unblock AdoptableHostTest.

Abolish cryptfs_revert_ext_volume, handle in caller. This allows us to
use DeleteDeviceIfExists, avoiding a spurious error message.

Not for security, but for consistency with the way we handle other
keys, and to move the length check to where it belongs.

Up until now, the FUSE mount logic has made two assumptions:
1. The primary external volume is an emulated volume on /data/media
2. Only the primary user is running, as user zero
These assumptions are fixed by the following changes
creating an EmulatedVolume per Android user and changing the
VolumeBase id format to append the user to the id, so
s/emulated/emulated-0/. This allows us mount separate volumes per user
Some additional refactorings to re-use/clean up code.

Our external partitions have no crypto header/footer, so we
only get the keysize and key. Our code has been implicitly
assuming that this keysize off of disk matches the crypto
type we have in our code (and thus matches the keysize our
code is using as well). We now make this assumption
explicit, and check for this and no longer allow external
code to pass a keysize in to cryptfs.

Moves away from crufty char* operations to std::string utility
methods, including android::base methods for splitting/parsing.
Rewrite of how Process handles scanning procfs for filesystem
references; now uses fts(3) for more sane traversal.
Replace sscanf() with new FindValue() method, also has unit tests.
Remove some unused methods. Switch almost everyone over to using
modern logging library.

Create IVoldListener and move most unsolicited vold events over to
this new interface. The remaining events will be routed through
method-specific listeners instead of a global one.
Move to upstream DISALLOW_COPY_AND_ASSIGN macro.

This moves fstrim, obb and appfuse commands over to the new Binder
interface. This change also separates creating/destroying and
mounting/unmounting of OBB volumes, which means they finally flow
nicely into the modern VolumeInfo/VolumeBase design.
We now generate unique identifiers for all OBB volumes, instead of
using a shady MD5 hash.
Change all "loop" and "dm" devices to tag the kernel resources with
a vold-specific prefix so that we can clean them up if vold crashes;
there are new destroyAll() methods that handle this cleanup.
Move appfuse mounting/unmounting into VolumeManager so it can be
shared. Move various model objects into a separate directory to
tidy things up.
