GP131: Update TEE_Param

Updates TEE_Param according to TEE Internal Core API version 1.3.1.

A compatibility type with a __GP11_ prefix is added for compatibility
with version 1.1. The two API functions TEE_InvokeTACommand() and
TEE_OpenTASession() are updated in a similar manner.

For the two TA entry functions TA_InvokeCommandEntryPoint() and
TA_OpenSessionEntryPoint() we are implementing those in directly in
user_ta_header.c since it's compiled with the TA and can used
conditionals based on __OPTEE_CORE_API_COMPAT_1_1.

These TA entry points calls __ta_open_sess() and __ta_invoke_cmd() to
convert TEE_Param to the compatibility __GP11_TEE_Param and in then call
the compatibility entry points __GP11_TA_OpenSessionEntryPoint() and
__GP11_TA_InvokeCommandEntryPoint().

Supplying __GP11_TA_OpenSessionEntryPoint() and
__GP11_TA_InvokeCommandEntryPoint() as function pointers ensures that
libutee doesn't try to look up the compatibility entry points when not
needed.

ldelf, libutee: add minimal Thread Local Storage support

Preparing for C++ support in TAs.

Adds enough runtime Thread Local Storage (TLS) support for the GNU C++
compilers (arm-linux-gnueabihf-g++, aarch64-linux-gnu-g++) to work with
OP-TEE. That is:

- A Thread Control Block,
- The __tls_get_addr() and dl_iterate_phdr() functions.

Note that __tls_get_addr() is an ABI helper so it has no prototype in a
user-accessible header file. dl_iterate_phdr() however is defined in
<link.h> and may be used in a TA. The file lib/libutee/include/link.h is
borrowed from Android's Bionic [1] with minor changes (added the
required #include statement and named the function parameters). A
similar <link.h> header is provided by other C libraries such as GNU
libc, musl and FreeBSD/NetBSD/OpenBSD.

libutee: arm64: Add support for function tracing of user TAs

Function tracing (ftrace) is a useful debugging technique to dump
function call graph for in-depth analysis of program execution and also
to get useful information in case of any program abort.

In case of TA, this function graph information is dumped in a buffer
kept in .bss section of corresponding instrumented TA. So this buffer
can be dumped to normal world in case TA session closes or in case of
any abort. Also size of this ftrace buffer is configurable per TA via
following config option during TA compilation:

CFG_FTRACE_BUF_SIZE=2048

Function tracing is completely optional debugging feature which could
be enabled via command line config option CFG_TA_FTRACE_SUPPORT=y.

Along with this user needs to add cflag: "-pg" to the files for whom
function graph is to be generated. Typically for the whole TA, it should
be compiled with CFG_TA_MCOUNT=y.

And in case user wants to set "-pg" for particular file, following should
go in corresponding sub.mk:

cflags-<file-name>-y+=-pg

Also, to generate function graph for user mode libraries enable
CFG_ULIBS_MCOUNT=y which will set "-pg" for all library files.

Currently this patch adds support for function tracing of 64-bit
TAs only.

CFG_ULIBS_GPROF builds the user mode libraries with -pg, which adds

This was historically used by gprof, but other tools can benefit from
this instrumentation. Therefore, rename the config flag as well as a
couple of source files to remove the reference to gprof.

Adds the infrastructure to collect profiling information from Trusted
Applications running in user mode and instrumented with -pg.
Enable with: CFG_TA_GPROF_SUPPORT=y.

Profiling support in itself adds no significant performance overhead.
Instrumented applications however may run 1.3x - 2x slower, and have a
larger .bss section (+1.36 times .text size for 32-bit TAs, +1.77 times
.text size for 64-bit ones).
