psp: provide encapsulation helper for drivers
Create a new function psp_encapsulate(), which takes a TCP packet and
PSP encapsulates it according to the "Transport Mode Packet Format"
section of the PSP Architecture Specification.
psp_encapsulate() does not push a PSP trailer onto the skb. Both IPv6
and IPv4 are supported. Virtualization cookie is not included.
