Subject: [PATCH] Make ScriptSig anonymous struct an exported type.

The previous commit modified the Vin ScriptSig field to be a pointer to an
anonymous struct so it could be properly omitted.  However, the callers
need to be able to create a new object to assign to the field, so this
commit makes the previous anonymous struct an exported type named
ScriptSig.
