     librpc:ndr: Update ndr_print_debug() and add macro NDR_PRINT_DEBUG_LEVEL

     Bumping the ABI to 3.0.0

     This is enhancement of NDR_PRINT_DEBUG macro with following new features:

     * debug level can be specified (NDR_PRINT_DEBUG always uses level 1)
     * the trace header shows the location and function of the caller
       instead of function 'ndr_print_debug', which is not really useful.

Is it not possible to keep the soname after this change?
I'm reviewing the changes now..
