Replace AC_CHECK_FUNCS with AC_CHECK_DECLS

It seems that AC_CHECK_FUNCS does not correctly detect when these "functions" are implemented as macros. (I've seen this happening on macOS, and Ubuntu 16.04 with snprintf and strndup respectively.) Replacing AC_CHECK_FUNCS (and the similar AC_REPLACE_FUNCS) with AC_CHECK_DECLS seems to solve this problem, though I don't have access to any systems that do not have these functions to be sure that it correctly detects them as missing.
