Subject: ipset 2.4 release

userspace changes:
  - Added KBUILD_OUTPUT support (Sven Wegener)
  - Fix memory leak in ipset_iptreemap (Sven Wegener)
  - Fix multiple compiler warnings (Sven Wegener)
  - ipportiphash, ipportnethash and setlist types added
  - binding marked as deprecated functionality
  - element separator token changed to ',' in anticipating
    IPv6 addresses, old separator tokens are still supported
  - unnecessary includes removed
  - ipset does not try to resolve IP addresses when listing
    the content of sets (default changed)
  - manpage updated
  - ChangeLog forked for kernel part

kernel part changes:
  - ipportiphash, ipportnethash and setlist types added
  - set type modules reworked to avoid code duplication
    as much as possible, code unification macros
  - expand_macros Makefile target added to help debugging
    code unification macros
  - ip_set_addip_kernel and ip_set_delip_kernel
    changed from void to int, __ip_set_get_byname and
    __ip_set_put_byid added for the sake of setlist type
  - unnecessary includes removed
  - compatibility fix for kernels >= 2.6.27:
    semaphore.h was moved from asm/ to linux/ (James King)
  - ChangeLog forked for kernel part
