The keyname binded to keyring return a wrong string when there are binary char larger than 127,
the sign extension will introduce unexpect FFFFFF string to the keyname.

Bringing this back temporarily for the same issue on sdcardfs.
Will remove once the kernel issue is resolved.

Select whichever is real dir instead of symbolic link from either /data/data
or /data/user/0. This is to minimize path walking overhead in kernel.
This works together with Change 369787

Unlinking keys rather than revoking them avoids bugs in certain kernel
versions without having to hack around the problem with an arbitrary 20
second delay, which is not guaranteed to be sufficient and has caused
full device hangs like in b/35988361.
Furthermore, in the context of filesystem encryption, unlinking is not
currently supposed to be any less secure than revoking. There was a
case where revoking (but not unlinking) keys will cause the filesystem
to deny access to files that were previously opened with that key.
However, this was a means of _access control_, which encryption is not
intended to be used for. Instead, file permissions and/or SELinux
should be used to enforce access control, while filesystem encryption
should be used to protect data at rest independently from access
control. This misfeature has also been removed upstream (and backported
to 4.4-stable and 4.9-stable) because it caused CVE-2017-7374.
Eventually we'd really like to make the kernel support proper revocation
of filesystem encryption keys, i.e. fully clearing all key material and
plaintext and safely waiting for any affected filesystem operations or
writeback to complete. But for now this functionality does not exist.
('sync && echo 3 > /proc/sys/vm/drop_caches' can be useful, but it's not
good enough.)

init reads files in /data/property/ but it is not ready to read when
trigger_load_persist_props is triggered by vold.decrypt.

Otherwise we potentially waste minutes of the users time copying
data that will never fit.
Also fix bug around storage calculation. It's confusing, but f_bsize
is not the value you're looking for; the real block size is f_frsize.

It's extremely difficult to test storage related logic on devices
that don't have physical SD card slots. So to support better
debugging and testing, add a new "virtual disk" feature which mounts
a 512MB file through loop device.
It relies on the kernel having the "loop.max_part" value set to
something other than 0 via the boot command line, since that allows
all the existing partition logic to fall into place.

Test: builds, boots, virtual disk works

The original default /fstab.{ro.hardware} might be moved to /vendor/etc/.

the hard-coded /fstab.{ro.hardware}.

The compatibility check assumes that the keymaster session was created
successfully which is a faulty assumption.
This patch adds propper error handling to the check.
