  Modified files:
    sys/sys              bus.h rman.h types.h 
    sys/kern             subr_bus.c 
  Log:
  Add two convenience functions for device drivers:  bus_alloc_resources()
  and bus_free_resources().  These functions take a list of resources
  and handle them all in one go.  A flag makes it possible to mark
  a resource as optional.
  
  A typical device driver can save 10-30 lines of code by using these.
  
  Usage examples will follow RSN.
  
  MFC:    A good idea, eventually.
