9ec0aeeab5 debug.h: merge both instances into ihk/debug.h
We do not need two debug.h files.

Take Fujitsu's STATIC_ASSERT over BUILD_BUG_ON because it is more used

e828398c8b do_mmap: don't pre-populate the whole file when asked for smaller segment
The linker maps parts of libs with different access flags,
so we cannot prepopulate the whole file.

04c11f35e9 xpmem: Add xpmem_openat
In arm64, glibc-open of /dev/xpmem is hooked in sys_openat. This
commit adds xpmem_openat which is called by sys_openat.
This commit silently applies copy_from_user fix to sys_open as well.

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
