Subject: [PATCH] Add a libipchecksum that contains the C IP checksum code.

This is useful for test code that wants to statically link the IP
checksum code. This is not currently possible because libnetutils
is vendor_available and making it available for static linking is
discouraged.

Test: m libnetutils libipchecksum
