CRC64

[Yaron Klein <klein@sanrad.com>]

Since the last draft sets the CRC64 as TBD, a good candidate can be the
one defined in:

http://www.openusenet.org/diablo/

Which is also applied in many other applications.

The polynom and sample code are in the file crctest.c in the latest
version:

polynom 0x0060034000f050b
init 0xfac432b10cd5e44a
