Workaround the KEEP_*() macro problem that sometimes causes the Aarch64

core: update optee_msg.h from Linux v4.12-rc1

The current Linux kernel (v4.12-rc1) has introduced a few changes in
optee_msg.h. The most important one is replacing the macro
OPTEE_MSG_GET_PARAMS() with a c99 style struct optee_msg_param params[]
member in struct optee_msg_arg.

The changes in core/arch/arm/kernel/thread.c and
core/arch/arm/tee/entry_std.c deals with that change.

core: FS: introduce dirfile interface

Introduces the dirfile interface which keeps a list of secure storage
objects. Each object is represented by the UUID of the owning TA, a hash
of the object, and a handle to the name used in normal world to store
the encrypted data of the object.

The interface allows queued atomic updates to avoid difficult races
during creation and renaming of objects.

By keeping the list of the secure object files in a single database the
collected state of the objects can be represented by a single hash or
even a counter. This gives some flexibility when implementing
anti-rollback protection.

Removes the unused/redundant fields magic, head_size, ds_size from

reflect the usage.

The size of the data stream is calculated from the total size of the
file minus attr_size. This makes the header static after it's
