nx-match: Separate raw match and header/pad pull/put
		
In the case of Open Flow 1.2, which is currently the only
time that OXM is be used, there is a 4 byte header before
the match which needs to be taken into account when calculating
the pad length. This complicates nx_match pull and put somewhat.

This patch takes an approach suggested by Ben Pfaff to separate the
encoding of the match and the adding of padding and, in the case of OXM,
a header.

ofp-util: Set switch_features actions to zero for Open Flow 1.1+
		
As of Open Flow 1.1 what was the actions element of
struct switch_features becomes reserved. As such
it seems sensible to always decode it as zero.
