Xiaodong Liu 3d66317189 crc64: add jones and iso format, crc64 code clean
1. Add normal and reflected bits order functions for ISO format and
   Jones coefficients format.
2. Add a multi-binary macro for crc64 functions.
3. In order to decrease number of repeated test.c and perf.c files,
   using crc64_funcs_test.c and cr crc64_funcs_perf.c.
4. Add crc64_example.c to take the demonstration role.
