r49158, r49159 and r49169 caused a build break for configurations where Netscape plugin support is turned off.
Created attachment 40989 [details] proposed patch In addition to fixing the build break with guards remove notImplemented() from PluginViewNone.cpp and make them just just be empty functions. The later change was suggested by Darin in an earlier similar bug (see https://bugs.webkit.org/show_bug.cgi?id=27940#c5). - As some functions were already empty in PluginViewNone.cpp, this also makes the PluginViewNone.cpp more consistent.
