3947bc2492 util/crc16: Add spdk_crc16_t10dif_copy to use in read strip and write insert
For DIF and DIX, read strip and write insert operation will copy
data together with DIF generation and verification.

This patch adds spdk_crc16_t10dif_copy for those cases.

e303567bc1 util/crc16: Add init_crc parameter as seed value to spdk_crc16_t10dif
Add init_crc parameter as seed value to spdk_crc16_t10dif API to generate
a CRC value spanning multiple separate buffers.

This will be necessary for upcoming DIF/DIX patches.

Having init_crc parameter is general, and so change the existing API
without adding seed version of the existing API.
