	modules/x86/task: _cpl0_switch.h 

Détails :
* modules/x86/task/_cpl0_switch.h, modules/scheduler/_synchq.c
(synchq_wait_unsafe): added comments about the race conditions we
anticipated

* modules/scheduler/scheduler.h (scheduler_retrieve_next_thread):
moved prototype to _scheduler.h, removed EXPORT_SYMBOL for it.

* modules/kmem/_kvmem_utils.c (__kvmem_add_range_to_used_list):
fixed an assertion bug when adding a used range at the head of the
list.

* modules/kmem/_kvmem_init.c (__kvmem_init): rearranged the way
the used/free range list are initialized. Also added a new range
of free virtual pages between 4k and the beginning of the GPFM =>
the kvalloc/etc... now return virtual addresses close to 4kB
(instead of 1GB)

* modules/kmem/_kvmem_alloc.c (kvalloc): removed superfluous
spin_unlock.
