* opensync_stats.proto gets compiled during the build
process. The pre-compiled files (opensync_stats.pb-c.*)
should not be patched any longer; I have also updated
some older patches for all of this this to work. OpenWrt
creates a temporary proto-c package for the host ARCH and
generates source and header files for the target platform.
This happens after all the patches have been applied and just
before the opensync compilation process.
