fb: allow to disable quicksettings

on 4.3 we had an extra settings option for it. Due that we want
to reduce the settings to improve the UX and due that
we are doing it this way on all dslv settings we change
the old 4.3 way.

Now it is very easy like dslv.....remove all tiles and QS
is completly disabled and cannot be opend any more. Notification
drawer shows the settings icon on the top right in this case.
As well compared to 4.3 this works on phones and tablets

TODO: add a hint for the user in settings when disabled like in dslv

fb: google please cleanup your translations.....systemUI cleanup

it is really at the moment a nightmare to see compile errors when
getting 100000 of warnings. Whatever we removed already on some
packages the warnings....but still a lot are there

This commit cleans up SystemUI

Reduce EntropyMixer seed size from 4096 to 512 bytes.

The suggested seed size from Linux drivers/char/random.c is 512 bytes
rather than the 4096 bytes currently used.

Make EntropyMixer mix in output of Hardware RNG into Linux RNG.

On devices with Hardware RNG (HW RNG), this makes EntropyMixer
periodically (every three hours) read 512 bytes from HW RNG and mix
them into the Linux RNG.

This is done without increasing Linux RNG's entropy estimates to
avoid having to trust the quality of the HW RNG. This approach cannot
reduce the quality of the Linux RNG output, but may increase it.
