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
CPUID 0x80000001 DBGPCSR 0x0 CPSR 0x80000013 (read from SPSR)
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.

Implemented wait in normal world

Instead of busy waiting in secure world, it is more efficient to wait
in normal world such that HLOS can schedule another task to execute
while waiting

- Added a new RPC command to wait in linux driver
- Remove wait_specific() hook in time_source, it seems can be a generic
function.
- This patch depends on "Implemented wait in normal world" in
optee_linuxdrver

Generic secure time layer

Provided a time source api in order to let soc vendors implement their
own secure counter

- Moved platform-dependent code out of tee_time.c to make it a generic
time layer.
- Added an abstract layer for platforms to implement their own secure
time source.
- Implemented arm cntpct as one of secure time source.
- Moved rtt0 related time operation from tee_time.c to tee_time_rtt.c,
act as another secure time source.
- Added tee_time_ree.c for the plaform that doesn't have secure time
source. In this case, using ree time as secure time source.

Cosmetic fixes for build output

By default, the OP-TEE build shows abbreviated output similar to the Linux
kernel. This commit fixes a number of deviations/inconsistencies.

- Always print a command in uppercase, followed by the target file.
- Make sure commands and file paths are nicely aligned, with two leading spaces
to make command output/errors better stand out.
- Remove some duplicate slashes in file paths. We use the following rule:
variables that hold directory names such as $(arch-dir) or $(platform-dir)
always have a trailing slash. The 'subdirs' and 'incdirs' variables used in
sub-makefiles are an exception because doing otherwise would needlessly
clutter the sub-makefiles.

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.

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.
