  Modified files:
    sys/kern             kern_sfbuf.c uipc_syscalls.c 
    sys/sys              sfbuf.h 
  Log:
  Fix a SFBUF memory leak in sendfile().  We were not properly tracking
  references which would lead to SFBUFs not getting freed when two or more
  sendfile()'s are operating on the same file at the same time (e.g. parallel
  ftp downloads of the same file).
  
  Get rid of the sf_buf->aux1 and aux2 hacks for sendfile.
  
  Add a sysctl to allow the number of free SFBUFs to be monitored.
