base-*: remove usage of printf

Browse Source 
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

/*
* \brief Core-specific 'printf' implementation
* \author Norman Feske
* \date 2010-08-31
*
* In contrast to regular Genode processes, which use the platform-
* independent LOG-session interface as back end of 'printf', core has
* to rely on a platform-specific back end such as a serial driver or a
* kernel-debugger function. The platform-specific back end is called
* 'Core_console'.
*
* This file contains the generic glue code between 'printf' and
* 'Core_console'.
