[CONSRV]
Move some output functions to the future console driver (i.e. for the moment, CSR console server functions SrvConsole* call ConDrv* functions).
Don't worry, internal headers will be rearranged, so that:
<ConDrv***_function_prototype>(...);
CSR_API(SrvConsole***)
{
...
}
constructions will be avoided in the future. For now, just make everything working.
