Switch to Nexus style data layout and allow usage of dalvik-cache from external sdcard.
Use internal data as in Nexus devices (sdcard0 is emulated). External sdcard now called sdcard1 and it's optional second partition can be used for dalvik-cache. Also apps can be moved to external sdcard using built-in asec machanism. This allows user to encrypt device including sdcard0 and place apps, dalvik-cache and media on external sdcard.
