Log message:
1. tcp_xmit_timer(): remove extra rtt decrement (t_rtttime is 0-based
while t_rtt was 1-based), update callers
2. define and use TCP_RTT_BASE_SHIFT instead of the hardcoded 2.
3. add missing shifts when t_srtt/t_rttvar are used.
4. update the comments: t_srtt uses 5 bits of fraction (not 3)
and t_rttvar uses 4 bits
5. remove obsolete/unused macros TCP_RTT_SCALE and TCP_RTTVAR_SCALE
6. make sure rttmin is not > TCPTV_REXMTMAX
