Subject: [PATCH 1/3] byteorder: move le32_add_cpu & friends from OCFS2 to core

- move inline functions which add native byte order variable to
  little/big endian variable to core header
  * le16_add_cpu(__le16 *var, u16 val)
  * le32_add_cpu(__le32 *var, u32 val)
  * le64_add_cpu(__le64 *var, u64 val)
  * be32_add_cpu(__be32 *var, u32 val)
- add for completeness:
  * be16_add_cpu(__be16 *var, u16 val)
  * be64_add_cpu(__be64 *var, u64 val)
