Turned demuxers into plugins. Change plugins naming scheme (see

xine_internal.h). Fixed load_plugins* to new API. Add iface version
into demux_plugin_t, add version checking into init_demux_plugin.
Fixed get_identifier from demuxers (void param). Turned libw32dll
into codec plugin (only compiling side yet).
