MFC r226447:

 Remove the ss_fltsz and ss_fltsz_local sysctl's which have
 long been superseded by the RFC3390 initial CWND sizing.

 Also remove the remnants of TCP_METRICS_CWND which used the
 TCP hostcache to set the initial CWND in a non-RFC compliant
 way.

MFC r242249:

 Adjust the initial default CWND upon connection establishment to the
 new and increased values specified by RFC5681 Section 3.1.

 The even larger initial CWND per RFC3390, if enabled, is not affected.

MFC r242250:

 When SYN or SYN/ACK had to be retransmitted RFC5681 requires us to
 reduce the initial CWND to one segment.  This reduction got lost
 some time ago due to a change in initialization ordering.

 Additionally in tcp_timer_rexmt() avoid entering fast recovery when
 we're still in TCPS_SYN_SENT state.

MFC r242255:

 Allow arbitrary MSS sizes and don't mind about the cluster size anymore.
 We've got more cluster sizes for quite some time now and the orginally
 imposed limits and the previously codified thoughts on efficiency gains
 are no longer true.
