Introduce an 'alias' field to 'struct format_field' to be able to use alternative name for the field. It is initialized with same string pointer as 'name' field. The free logic checks the 'alias' pointer being reset by user and frees it. This will be handy when converting data into CTF, where each field within event needs to have a unique name (while this is not required for tracepoint). Converter can easily assign unique name into the format_field struct.
