Currently, NETIF_F_TSO_MANGLEID indicates that the inner-most ID can
be mangled. Outer IDs can always be mangled.
Make GSO preserve outer IDs by default, with NETIF_F_TSO_MANGLEID allowing
both inner and outer IDs to be mangled.
This commit also modifies a few drivers that use SKB_GSO_FIXEDID directly.

The titles do not look very nice in the table of contents generated by
Sphinx.
I also think it is obvious that the documents are describing offloads
in the Linux Networking Stack.

This patch renames offload files. This is necessary for Sphinx.
Also update reference to checksum-offloads.rst file.
Whole kernel code was grepped for references using:
$ grep -r "\(segmentation\|checksum\)-offloads.txt" .
There should be no other references
to {segmentation,checksum}-offloads.txt files.
