Revert "Keyguard: Use translucent UI"

This reverts commit 13c0f490b9abbbba05fdda72f9b1eafffe559cb8.
Keaguard: enable translucent keyguard by default

currently it is possible to enable it per device over an overlay and it is disabled
by default. Enable it by default but respect general transluscent disable from
device tree. Manta eg disables this feature due of graphical glichtes.

[1/2] base: volume panel styles and tweaks

From CM - Support different styles of the volume dialog
allows expanding the dialog to show all adjustable volumes

New setting MODE_VOLUME_OVERLAY defines the style
0 = unchanged - single slider
1 = expandable - button beside to slider to expand - this is the default
2 = expanded - open already expanded

This also adds using setting VOLUME_LINK_NOTIFICATION
to allow adjusting the separation of notification and ringer volumes
default=1

This also already adds the new setting
VOLUME_ADJUST_SOUNDS_ENABLED default=1
to allow disabling the volume adjust sound

fixed some minor code style issues

- add all values multi user configurable
