  Log:
  Add support for shared interrupts to the kernel. This code is meant
  be (eventually) architecture independent. It provides an emulation
  of the ISA interrupt registration function register_intr(), but that
  function does no longer manipulated the interrupt controller and
  interrupt descriptor table, but calls the architecture dependent
  function setup_icu() for that purpose.
  
  After theISA/EISA bus code has been modified to directly call the new
  interrupt registartion functions (intr_create() and intr_connect()),
  the emulation of register_intr() should be dropped.
  
  The C level interrupt handler function should take a (void*) argument,
  and the function pointer type (inthand2_t) should defined in some  other
  place than isa_device.h.
  
  This commit is a pre-requisite for the removal of the PCI specific shared
  interrupt code.
