    Require fontsproto < 2.1.3 for matching function prototypes
    
    Building libXfont-1.4.x against fontsproto 2.1.3 causes clang
    complaints of:
    
    patcache.c:130:1: error: conflicting types for 'CacheFontPattern'
    CacheFontPattern (FontPatternCachePtr cache,
    ^
    patcache.c:176:1: error: conflicting types for 'FindCachedFontPattern'
    FindCachedFontPattern (FontPatternCachePtr cache,
    ^
    
    due to the constification of arguments not matching.

    Fix buffer read overrun
