This patch adds a new field to the state templates. If this extension
field is != 0, then the line is only applied to the final state table
if the extension is supported. Once a line is applied to the final
table, all further templates for this state from the same pipeline
part are ignored. This allows removing some extension checks from the
state handlers, which cleans them up and saves a few CPU cycles when
applying the states.
This creates an nvts version of this function, and removes the nvts
code from the original one. The nvts version is used by the nvts
pipeline implementation, the original one by the nvrc-only, atifs and
ffp one.
This code creates the structures and the pipeline selection, as well
as the caps filling. It does not yet move the actual code around,
since this will be a bigger task.
