package/libsvg: new package

Libsvg provides a library for parsing SVG content in files or buffers.
Libsvg does not do any rendering, but instead provides a function-based
interface that can be used by various rendering engines.

+Newer expat versions use different declarations of the following functions:
+
+static void _svg_parser_sax_start_element ();
+static void _svg_parser_sax_end_element ();
+static void _svg_parser_sax_characters ();
+
+We need to patch the libsvg source to not follow into a build error like
+   "static declaration of 'foo' follows non-static declaration"
+and use the functions from the expat library instead from the libsvg source.

+Patch based on
