[librsvg: 5/11] Rename Gradient to UserSpaceGradient

    Rename Gradient to UserSpaceGradient
    
    I'm going to apply the same treatment to have a UserSpacePattern.
    However, *that* one cannot be called Pattern because "struct Pattern"
    is already for the <pattern> element.  Gradients don't have this name
    collision because their elements are called <linearGradient> and
    <radialGradient>.
