* Added syscall restart support for connect(), accept(), send(), recv(),
  which are implemented via ioctl()s. The actual restart support is done
  in the net stack driver's ioctl() hook. Lower layers need to correctly
  deal with socket timeouts, though, for which the stack module provides
  support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
  occurred earlier, so that trying to connect to an unused port fails
  immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
  TCPEndpoint::_HandleReset() does the job. Got rid of
  TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
  correctly and could even be reused when trying to connect again (as
  was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.
