user code also needs these defines; there was a hard-coded
definition left out from debugging that didn't get cleaned up

sprintf is implemented as snprintf(..., INT_MAX, ...) which will overflow
the argument pointer for the end, then fix the end to be -1.
This technically works but we know the actual buffer size in all these
call sites, might as well do this properly

The linker maps parts of libs with different access flags,
so we cannot prepopulate the whole file.

This fix is rejected because it only makes the setfsuid test in ostest
pass and doesn't fix the other issues including the one in which file
I/O could be done with the old fsuid because an mcexec thread with an
arbitrary tid could handle the system-call offload request.
Explanation of the rejected fix:
setfsuid() proceeds as follows:
1. McKernel asks mcexec for __NR_setfsuid (set)
2. mcexec calls setfsuid, reports the id to McKernel
3. McKernel asks mcexec for __NR_setfsuid (get)
4. mcexec calls mcexec_getcred(), reports the id to Mckernel
5. McKernel sets proc->fsuid to the obtained value
tid of mcexec on the 2nd and 4th step could be different. So this
fix lets mcexec report its tid on the 2nd step and McKernel specify
it in the 3rd step.

The original fujitsu code added a whole new ihk_mc_perfctr_stop_first
function, duplicating a lot of code - add a flag to existing function
instead.

The process of making a child process zombie and the process of setting
the parent of the child process to process ID 1 are excluded.

We need to separate the two because the heap of a PIE is created in
the area to which it is mapped.

user_start

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

Its call site is moved before numa_init() as well because
monitor_init() defines ihk_os_monitor that was used in
rusage_total_memory_add() called from numa_init().
I didn't revert this modification because I don't want to touch the
working code.

Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

some archs do not have the simple open/unlink variants, while the *at

functions
