f9d8d98af1 sysfs: add missing symlinks for cpu/node 
Add the following patterns of symlinks:
 - /sys/bus/cpu/drivers/processor/cpu*
 - /sys/bus/node/devices/node*

And slightly change how /sys/devices/system/cpu/cpu*/node* are created
to avoid duplicate lookups

3185334c1c 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

6df4bd8f8c Fix a few more warnings 
Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

aa7cb970c4 ihk_os_getrusage(): Compile LWK-specific results in mcctrl 
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header

1aac2c8e23 add CPU timer initialization (refs #402) 
There is no actual initialization in x86 now.
The initialization rely on hardware reset and Linux initialization.
