  Log:
  Split out kill(2) syscall service routine into user-level and kernel part, the
  former is callable from user space and the latter from the kernel one. Make
  kernel version take additional argument which tells if the respective call
  should check for additional restrictions for sending signals to suid/sugid
  applications or not.
  
  Make all emulation layers using non-checked version, since signal numbers in
  emulation layers can have different meaning that in native mode and such
  protection can cause misbehaviour.
  
  As a result remove LIBTHR from the signals allowed to be delivered to a
  suid/sugid application.
