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.

# config/check_decls.m4
|

|

# This file redefines the standard Autoconf macro AC_CHECK_DECL,
|
||||
# and adds a supporting function _AC_UNDECLARED_WARNING, to make
|
||||
# AC_CHECK_DECLS behave correctly when checking for built-in library
|
||||
# functions with clang.
|
||||
|
||||
# This is based on commit 82ef7805faffa151e724aa76c245ec590d174580
|
||||
