Log Message:
Pull up following revision(s) (requested by riastradh in ticket #952):

        sys/sys/endian.h: revision 1.32
        sys/sys/endian.h: revision 1.33
        sys/sys/endian.h: revision 1.34
        sys/sys/endian.h: revision 1.35

break the cycle: this does not need <sys/types.h> it only needs <sys/stdint.h>

arpa/inet.h: Define htonl &c. under _POSIX_C_SOURCE >= 200112L too.
These do not require _XOPEN_SOURCE as of POSIX 2001:
https://pubs.opengroup.org/onlinepubs/009696799/functions/htonl.html

XXX Since this change is actually sys/endian.h, in principle it might
bleed into header files than just arpa/inet.h.  But sys/endian.h is
not used by anything that looks especially risky to me.

PR standards/57806: #include <arpa/inet.h> fails to define
htonl/htons/ntohl/ntohs under _POSIX_C_SOURCE=200809L

sys/endian.h: Hide le32enc/be32enc/... under _NETBSD_SOURCE.
These are non-standard extensions, so they should not be exposed by,
e.g., _XOPEN_SOURCE=700.

PR standards/57807: #include <arpa/inet.h> spuriously defines
le32enc/be32enc/... under _XOPEN_SOURCE=700

sys/endian.h: sync comment with code
