  Modified files:
    sys/netinet          tcp_input.c tcp_subr.c tcp_var.h 
  Log:
  Provide a sysctl to toggle reporting of TCP debug logging:
  
   sys.net.inet.tcp.log_debug = 1
  
  It defaults to enabled for the moment and is to be turned off for
  the next release like other diagnostics from development branches.
  
  It is important to note that sysctl sys.net.inet.tcp.log_in_vain
  uses the same logging function as log_debug.  Enabling of the former
  also causes the latter to engage, but not vice versa.
  
  Use consistent terminology in tcp log messages:
  
   "ignored" means a segment contains invalid flags/information and
     is dropped without changing state or issuing a reply.
  
   "rejected" means a segments contains invalid flags/information but
     is causing a reply (usually RST) and may cause a state change.
