Currently, vold only supports MMC (for SD cards) and SCSI (for USB
drives) devices. It does not recognize any device whose major number is
not one of those used by MMC and SCSI. Unfortunately, virtio-blk is one
such device. It is used by the new Android emulator (a.k.a. qemu2,
featuring the "ranchu" virtual board) for SD card emulation.
In order to make this virtio-blk based SD card device appear in Android
and appear as an SD card (rather than a USB drive), changes have to be
made to both vold (wherever the device major number is checked) and
ranchu's storage configuration. This CL implements former.
This is a stop-gap solution for emulator in nyc.
A longer term solution in-tune with upstream kernel is in the pipes.
Updated from aosp/master version.

This is a special profile folder where apps will leave profile markers
for the dex files they load and don't own. System server will read the
markers and decide if the apks should be fully compiled instead of
profile guide compiled.

Added a new call change_user_key which changes the way that disk
encryption keys are protected; a key can now be protected with a
combination of an auth token and a secret which is a hashed password.
Both of these are passed to unlock_user_key.
This change introduces a security bug, b/26948053, which must be fixed
before we ship.

Add new misc directories to list of paths that we lock/unlock in
emulation mode. When booting a device without native-FBE and without
emulation, make sure we "unlock" any emulated settings on user 0;
MountService handles this for secondary users later during boot.

Give callers the option of preparing CE and/or DE storage. The
framework will only prepare CE storage after the CE keys have been
unlocked for that user.
When init is calling enablecrypto, kick off the work in a thread so
that we can make other calls back into vold without causing
deadlock. Leaves blocking call intact for framework callers.
Clean up 'vdc' tool to send useful transaction numbers, and
actually watch for the matching result to come back. This fixes
race conditions when there are multiple 'vdc' callers.
Also add other system and misc directories to match spec.

e2fsck and fsck.f2fs must run in the fsck domain. Add call to
setexeccon() to tell selinux to run in the fsck domain on exec.

Mainly a refactor, but with a substantive change: Keys are created in
a temporary location, then moved to their final destination, for
atomicity.
