Adds support for running initialization and finalization functions in
TA ELF files. Such functions are used, for instance, by C++ compilers
to construct and destruct global objects. They can also be used in C
thanks to __attribute__((constructor)) and __attribute__((destructor)).
A global structure is added to libutee. ldelf is responsible for
filling it with the addresses of the functions pointer arrays present
in the ELF files whenever such a file is loaded. Since the number of
arrays is unknown at compile time (it depends on how many ELF files are
loaded, and whether they have constructors or destructors), memory is
allocated on the TA heap.
Two helper functions are introduced: __utee_call_elf_init_fn() and
__utee_call_elf_fini_fn(). They are used when the TA instance is
created and torn down, as well as by dlopen().
