Fix configure's AC_CHECK_DECLS tests to work correctly with clang.

Back-port commit 16fbac39f into 9.3 and 9.2, so that these
out-of-support branches can be built with clang without wading
through a pile of warnings about strlcpy and related functions.
check_decls.m4 required some adaptation to work with autoconf 2.63,
but nothing too major.
