Suppress clang-analyzer-security buffer-handling diagnostics on the
plan-mandated __builtin_memcpy word loads and bugprone swappable-
parameter diagnostics on the C-standard signatures; wrap the autoconf
substitution tokens in clang-format off/on (the space clang-format wants
before the closing @ would break config.status substitution).

Exact OpenBSD semantics: strlcpy returns strlen(src) and writes at most
size-1 bytes plus NUL; strlcat returns dlen + strlen(src) with
dlen = min(size, strlen(dst)) and never reads past size bytes in dst.

Word-at-a-time memcpy/memmove/memset/strlen/strcmp implementing the
level-1 string slice. memcpy carries an optimize(no-tree-loop-
distribute-patterns) attribute: GCC's loop-distribution pass rewrites
its word-copy loop into a self-recursive memcpy@plt call at -O2/-O3
otherwise.
