Adds support for dumping the call stack of a user-mode TA when it
panics. Stack unwinding happens in kernel mode by re-using
abort_print_error() in core/arch/arm/kernel/abort.c. Like for abort
dumps, the helper script scripts/symbolize.py may be used to obtain
source-level information.
This feature is enabled by default. Set CFG_UNWIND=n to disable it
(or CFG_TEE_CORE_DEBUG=n).
In libutee, the utee_panic() syscall wrapper is renamed __utee_panic()
and now takes an additional parameters: a stack pointer, in addition to
the panic code. utee_panic() is written in assembly and pushes some
registers onto the stack before calling __utee_panic(). When it is time
to return from syscall_panic(), tee_svc_sys_return_helper() uses the
stack pointer to get the information needed to unwind the TA stack.
A struct abort_info is created and abort_print_error() is called.
