When using make_f2fs to format a filesystem with quota enabled, make_f2fs
will write quota record with group id equtal to make_f2fs's execution
group id.
Vold shall run as root group so that make_f2fs forked by vold will enherit
vold's root group. Make_f2fs can then write quota record with group id for
root group and therefore kernel quota driver can find quota record for
root group.

For apps with sharedUserIds, sandbox/shared:<shared-user-id> is
currently used as sandbox root. Given that <shared-user-id> can
be upto 255 characters, adding "shared:" might tip over the
filename limit on ext4 filesystems. So, instead use
sandbox/shared/<shared-user-id> as the sandbox root.

Remove the Speck encryption support. It was eventually
decided not to allow Speck in Android P, so this code
is no longer needed and wasn't used outside of testing.
Note we don't just "git revert" the original commit
(38723f23ff) because we want
to retain the infrastructure for allowing new types of
crypto algorithms in the future.
Bug: 112009351
Test: Attempted to setup a device with ro.crypto.fde_algorithm set to Speck, and Speck was rejected and the system defaulted to AES.

string::find() looks in every position of the string for a match.
We switch to android::base::StartsWith() so we only look for
a match in the first position.

This is same as what we are doing as of P, symlinking
"/mnt/user/<user-id>/primary" to primary volume path.

This file should avoid F2FS GC, since it directly access block device based
on fibmap.

Vold is updated to create package specific sandboxes for primary
volume and mount them at
"/mnt/user/<user-id>/package/<package-name>/<primary-label>".
This will later be mounted at /storage when a new process starts.
Bug: 111890351
Test: Manually verified that a package has access to "/sdcard" and
"/storage/emulated/0", both of which are just the package specific
sandboxes and the package doesn't have access to other sandboxes
and can't see other package names.
