can: add ISO 15765-2:2016 transport protocol
CAN Transport Protocols offer support for segmented Point-to-Point
communication between CAN nodes via two defined CAN Identifiers.
As CAN frames can only transport a small amount of data bytes
(max. 8 bytes for 'classic' CAN and max. 64 bytes for CAN FD) this
segmentation is needed to transport longer PDUs as needed e.g. for
vehicle diagnosis (UDS, ISO 14229) or IP-over-CAN traffic.
This protocol driver implements data transfers according to
ISO 15765-2:2016 for 'classic' CAN and CAN FD frame types.

[mkl: Removed "WITH Linux-syscall-note" from isotp.c.
Fixed indention, a checkpatch warning and typos.
Replaced __u{8,32} by u{8,32}.
Removed always false (optlen < 0) check in isotp_setsockopt().]
