Check of the identity of the TA invoking a TA operation

On the following operations

same as the one that opened the session.

Merge tee_{core,uta}_trace.h into libutil

Merges tee_core_trace.h and tee_uta_trace.h into a common trace.h
in libutil. Since the trace functions now resides libutil they have
to rely on core and libutee to provide functions to print to the
log device.

* Adds TAMSG() and TAMSG_RAW() to log TA related events
* Removes the TRACE_ALWAYS level

Cleanup loading/unloading of a TA

* A TA is only loaded via tee-supplicant, directly supplying a
pointer to the TA binary is not supported any longer.
This requires and update to the client lib to avoid leaking
shared memory.
* The shared memory used to load the TA is freed as soon as the
TA have been loaded into secure memory
* Divides tee_ta_init_session() into sevaral functions
* Divides tee_ta_close_session() into two functions
* Divides tee_ta_load() into several functions with one
separate function for signature verification
* Removes some unused code for kernel TAs
* Removes the option to lock/unlock a TA is only used by kernel
TAs which we don't support any longer.
* Removes the static global tee_rs. Switch to use Thread Local
Storage pointer provided by the thread handler.
* Adds TA_FLAG_USER_MODE by default to TA header since
all TAs are user mode TAs now.
* Reformats user_ta_header.c to make checkpatch less unhappy with it.

Add plat-vexpress

* Initial support for Versatile Express of FVP with ARM Trusted
Firmware (ATF below)

* Use entry vector for entering TEE

Align interface between TEE and secure monitor with the interface
between OPTEED in ATF and TEE.

Uses an ATF compatible entry vector for entering TEE from internal
secure monitor.

Internal secure monitor saves entry reason to be able to tell when
switching back to nonsecure world if r0-r3 should be preserved (FIQ case)
or returned as is (normal call case).

* Many small fixes of generic problems that could affect other platforms
too.

* Disable unaligned data accesses by adding compiler flag
-mno-unaligned-access

* Adds support for Versatile Express of QEMU with 8 MiB of secure DRAM
