Subject: [PATCH] Update x86 machine/endian.h from upstream

After download new version from upstream (OpenBSD 1.17) did the
following:
 * changed all u_int* types to uint*
 * add #include <sys/types.h>

All these changes are Android-specific and had been done before for
previous version (1.14).

Bug: http://code.google.com/p/android/issues/detail?id=54465
Change-Id: Ieb44e7fce4e794d997bb00ee0dd417fb61521720
