init: Make restorecon_recursive work for /data/

    Apply restorecon_recursive to all of /data.

they removed all the adhoc restorecon_recursive of subdirectories
of /data/ and replaced it with:

    # Set SELinux security contexts on upgrade or policy update.
    restorecon_recursive /data

Unfortunately, that is a no-op because restorecon doesn't recurse
through /data/ unless you add a FORCE flag.

Since the expectation seems to be that the recursive restorecon
in init will actually work, update the built-in to add the force
flag and a flag to allow /data/data to also be recursed through.

Remove the adb usb vendor id whitelist.

If there are bad vendors, we should blacklist them. Whitelisting the entire
world is crazy.

Disable vendor id filtering for Linux.

It's time we switched to blacklisting any problematic devices rather than
slowly whitelisting the entire world. This seems to work for me, but let's
see how other people get on before coming back to actually remove the list.

We'll also need to find a Mac to test the equivalent Mac change.

Disable vendor id filtering for OS X.

Companion patch for change I2bf583a27f9a3f98ef006ea62b906a4f89960507.

Due to the use of USB class 0xff it's not possible to register a listener
which uses the OS methods for filtering notifications, so this patch
also introduces a check in the notification listener which checks the
class, subclass, and protocol for the interface each notification relates
to.
