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.

* Keeps compatible interface from tee_kta_trace.h
* Adds TAMSG() and TAMSG_RAW() to log TA related events
* Removes the TRACE_ALWAYS level

plat-vexpress: fix non-debug build

Fixes a number of build errors when 'PLATFORM=vexpress' and 'DEBUG=':
- '<var> may be used uninitialized'
- 'dereferencing type-punned pointer will break strict-aliasing rules'
This one is addressed by adding -fno-strict-aliasing to the cflags for the
problematic files, which is a temporary solution.
- 'inlining failed'

Also, make sure tee_svc_syscall_table is aligned on a 32-bit boundary.
Otherwise, an alignment fault might occur:
ERR [0x0] TEE-CORE:tee_pager_print_error_abort:101: data-abort at 0x602f16b
FSR 0x1 PC 0x6007bd4 TTBR0 0x603804A CONTEXIDR 0x1

ERR [0x0] TEE-CORE:tee_pager_handle_abort:164: [TEE_PAGER] alignement fault! (trap CPU)

Note: on Foundation_v8, I measured a ~3x speedup between debug and non-debug
builds for asymmetric crypto tests.

Reentrancy fixes

Before this patch: The normal world was only allowed to enter
secure world with one thread at a time.

After this patch: The normal world may try to enter secure world
with as many threads as it likes, secure world will return busy
when no more threads can be allowed. Secure world still only allows
one active thread at a time, but during RPC another thread may enter
and do some work. This is needed for cancellation to work.

* Adds a mutex that waits in normal world if busy
* Adds a new RPC service to wait in normal world
* Imports bitstring.h from FreeBSD to aid mutex implementation
* Adds a critical section in tee_ta_init_session
* Unmaps TA before RPC exit and maps it again on return to handle
rescheduling of threads during RPC
* Doesn't clear a1-a3 when returning busy
* Bugfixes vector_std_smc_entry

This patch depends on the "Allow parallel entries to secure world"
patch in optee_linuxdriver.
