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

3ce7763715 x86 mem init: do not map identity mapping 
init_normal_area was mapping identity lookups (phys = virt) from 0,
leading to many undetected null pointer dereferences in init_pt (but
not in new process page tables leading to odd behaviour)

This also makes the code use the set_pt_large_page() function, cleaning
it up a bit
