Bump version to 3.98
    
    Several patches from Fedora were applied upstream, so we can just remove
    them. The other patches are:
        - xawtv-3.95-strip.patch:
    	Fedora-specific customization;
        - xawtv-3.95-libv4l2.patch:
    	libv4l2 patch (we prefer to keep this out-of-tree for now,
    	since pure-xawtv is useful for some tests. Maybe later,
    	we may have a separate driver for V4L2 and for libv4l2.
        - xawtv-3.95-font.patch
    	Not sure if this is fedora-specific, or if it is related to
    	pure upstream changes at Xorg fonts;
        - xawtv-3.95-vbi-compile-fix.patch
    	Seems to be either uneeded or Fedora-specific. Upstream compiles
    	fine without this change on RHEL6.
