[Linux-kernel-mentees] [PATCH v4 13/14] parsing_c: cpp_token_c: Introduce MACROANNOTATION hint

A better way of denoting attributes is to pass attribute information
from SmPL to the C parser. However, a temporary solution is to introduce
a MACROANNOTATION hint to cpp_token_c.ml so that the parser can identify
attributes easily.

This hint can be used as follows in standard.h, the user provided
macro-defs file or the given C file itself:

	#define __attribute_name MACROANNOTATION

By default, __attribute_name would be identified as a comment. Using the
above hint, __attribute_name would be identified as an attribute and
transformations from SmPL would be performed as if __attribute_name is
an attribute, not a comment.
