ADHD: Provide better diagnostics for function entry & exit

Details

  Since ADHD is a multithreaded application, where different threads
  will use the same functions, I think it is beneficial to provide
  more context, at sufficient verbosity, about how functions are being
  entered an exited.

  This change alters VERBOSE_FUNCTION_ENTER() and
  VERBOSE_FUNCTION_EXIT() to take a varadic set of parameters,
  facilitating the output of the arguments passed to the function.

Testing

  o tegra2_kaen

    killed default instance of gavd
    /usr/bin/gavd --verbose=10
    grep gavd /var/log/messages

      gavd[2859]: daemonize: release mode.
      gavd[2859]: signal_start
      gavd[2859]: threads_start: 'Internal Microphone'
      gavd[2859]: threads_start: 'Internal Headphone'
      gavd[2859]: beg gpio_switch_monitor(Internal Microphone, tegra-seaboard Mic Jack, 4, (null), (null))
      gavd[2859]: beg sys_input_find_device_by_name(tegra-seaboard Mic Jack)
      gavd[2859]: utils_execute_command: '/usr/bin/amixer set 'Speaker'   100% && /usr/bin/amixer set 'Headphone' 100% && /usr/bin/amixer set 'Digital'   100% && /usr/bin/amixer set 'Left Speaker Mixer DACL'  on && /usr/bin/amixer set 'Right Speaker Mixer DACL' on && /usr/bin/amixer set 'Left Speaker Mixer DACR'  on && /usr/bin/amixer set 'Right Speaker Mixer DACR' on && /usr/bin/amixer set 'ADC Input' 'DMIC'' succeeded.
      gavd[2859]: beg gpio_switch_monitor(Internal Headphone, tegra-seaboard Headphone Jack, 2, /usr/bin/amixer set 'Speaker' off && /usr/bin/amixer set 'Int Spk' off && /usr/bin/amixer set 'Headphone' on, /usr/bin/amixer set 'Speaker' on && /usr/bin/amixer set 'Int Spk' on && /usr/bin/amixer set 'Headphone' off)
      gavd[2859]: beg sys_input_find_device_by_name(tegra-seaboard Headphone Jack)
      gavd[2859]: end sys_input_find_device_by_name(tegra-seaboard Mic Jack)

  o x86-mario

    killed default instance of gavd
    /usr/bin/gavd --verbose=10
    grep gavd /var/log/messages

      gavd[2967]: compiled for target machine: 'x86-mario'
      gavd[2967]: beg daemonize(void)
      gavd[2967]: Child process: '2968'.
      gavd[2968]: daemonize: release mode.
      gavd[2968]: signal_start

   There is less output because x86-based machines do not have any
   hardware monitoring yet.
