Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

Use a hand-crafted packet generator script to inject packets with
deliberately broken ip4 and udp checksums - and the appropriate
checksum offload flags - into src/vnet/interface_output.c
vnet_interface_output_node_inline(...), and make sure that the
resulting checksums are correct.
Use the packet tracer to catch one of the packets. Parse through the
packet trace, and make sure that the checksums have been correctly
computed.
