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.
