Modified Files:
        src/lib/libexecinfo: unwind.c

Log Message:
make the backtrace()'s tracer() return _URC_FOREIGN_EXCEPTION_CAUGHT
when the array is full.  it won't be able to do any more work if so,
and avoids infinite loops in unwinding as seen on arm64.

XXX:  lack of signal support here means that backtrace() is useless
XXX:  from a signal handler, such as attempting to display the stack
XXX:  when handling a SIGSEGV.
