    x11-toolkits/pangox-compat: fix build with clang 15
    
    During an exp-run for llvm 15 (see bug 265425), it turned out that
    x11-toolkits/pangox-compat failed to build with clang 15:
    
      pangox.c:983:15: error: incompatible integer to pointer conversion assigning to 'PangoFontMetrics *' (aka 'struct _PangoFontMetrics *') from 'int' [-Wint-conversion]
            metrics = pango_font_metrics_new ();
                    ^ ~~~~~~~~~~~~~~~~~~~~~~~~~
      pangox-fontmap.c:944:9: error: incompatible integer to pointer conversion initializing 'char *' with an expression of type 'int' [-Wint-conversion]
        char *files_str = pango_config_key_get ("PangoX/AliasFiles");
              ^           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
    This is because pangox-compat uses two private functions from the main
    pango library, which are not declared in the public pango headers.
    
    Fix the errors by adding the two private functions in
    pango-impl-utils.h, copying the declarations from pango-font-private.h
    and pango-utils-private.h.
