Message:

• Added a syscall and some user functions to manipulate the Simulation Helper
• Changed the the way the Vseg -> Pseg mapping is made during the boot to better utilize the address space (+ adaptation of the algorithm in memo)
• Fixed a bug in boot_init (vobj_init): the vobj initialization could only be made for the first application (ptpr was not changed)
