base generic code: * Remove unused verbosity code from mmio framework * Remove escape sequence end heuristic from LOG * replace Core_console with Core_log (no format specifiers) * move test/printf to test/log * remove `printf()` tests from the log test * check for exact match of the log test output base-fiasco: * remove unused Fiasco::print_l4_threadid function base-nova: * remove unused hexdump utility from core base-hw: * remove unused Kernel::Thread::_print_* debug utilities * always print resource summary of core during startup * remove Kernel::Ipc_node::pd_label (not used anymore) base*: * Turn `printf`,`PWRN`, etc. calls into their log equivalents Ref #1987 Fix #2119
