* Mapping attached part of segment is done at attach time instead of
make time to work with runtimes (e.g. OpenMPI) xpmem_make-ing the
entire user-space
* Mapping attached part of segment at attach time can be turned off by
specifying xpmem_remote_on_demand in kernel argument
* Mapping attachment chooses appropriate page-sizes, i.e., largest
allowed by memory range and segment page boundary
Fixes: a8696d8 "xpmem: Support large page attachment"

It was telling the vmap allocator to release a wrong address range
(physical address range).

We do not need two debug.h files.
Take Fujitsu's STATIC_ASSERT over BUILD_BUG_ON because it is more used

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

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

This includes the following fix:
send_syscall, do_syscall: remove argument pid

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

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

search_free_space changed since this was implemented and the code is
no longer compatible
Looking at it again, the function is not used anywhere other than syscall.c
and the second function does not seem to fix anything specific so this
just removes the untested side.

Fujitsu: POSTK_DEBUG_ARCH_DEP_27
The gencore() and freecore() code in gencore.c is guarded by
POSTK_DEBUG_ARCH_DEP_18, so the call to these functions should
also be guarded, otherwise linking fails.
Previously the allocator would return all availble memory for a
request of 0 pages. This is rather counter-intuitive and left no
memory for subsequent allocations.
