tracing: Use ? : shortcut in trace macros
Instead of having:
#define __assign_str(dst, src) \
memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ? \
__data_offsets.dst##_ptr_ : "(null)", \
__get_dynamic_array_len(dst))
Use the ? : shortcut and compact it down to:
#define __assign_str(dst, src) \
memcpy(__get_str(dst), __data_offsets.dst##_ptr_ ? : "(null)", \
__get_dynamic_array_len(dst))
