Ported keymaster_tuna to keymaster0 interface.
keymaster_tuna.cpp almost exactly matches keymaster HAL 0 interface,
only several small changes were needed.
Note the change in the flags (KEYMASTER_BLOBS_ARE_STANDALONE): this
is required for hardware backed storage of the disk encryption key
to function, see keymaster_check_compatibility() function in
system/vold/cryptfs.c
