debug messages: implement dynamic debug
...
Heavily inspired off linux kernel's dynamic debug:
* add a /sys/kernel/debug/dynamic_debug/control file
(accessible from linux side in /sys/class/mcos/mcos0/sys/kernel/debug/dynamic_debug/control)
* read from file to list debug statements (currently limited to 4k in size)
* write to file with '[file foo ][func bar ][line [x][-[y]]] [+-]p' to change values
Side effects:
* reindented all linker scripts, there is a new __verbose section
* added string function strpbrk

Redirect kmsg to /dev/log and detect hungup
...
1. ihkmond retrieves kmsg when the amount of kmsg exceeds the threashold and
/dev/mcosX is deleted
2. ihkmond periodically monitors OS status change to detect hungup

Start mcklogd before McKernel to avoid deadlock
...
McKernel blocks forever waiting for mcklogd to retrieve kmsg when
kmsg bufer is full with boot log and mcklogd isn't running.
