0cde7bc6d6 Reduce the number of vegas parameters. 
We need to tune these, but we're not likely to need the subtle differences
between a few of them. Removing them will prevent our consensus parameter
string from becoming too long in the event of tuning.

acdc0ecdd4 Reset the min value if we hit cwnd_min. 
This can avoid circuits getting stuck due to an abnormally low min value.

4444f5f4ed Use EWMA instead of bare rtt for min rtt. 
This allows us to average out minimums due to lulls in activity a bit more.

08c3ee8eca Create slow-start max for n_ewma_cnt. 
Since slow-start now checks every sendme, lower EWMA is better.

832a1d9fae Implement RFC3742 Limited Slow Start 
RFC3742 updates the cwnd every sendme during slow start, and backs off of the
exponential growth based on a cap parameter.

d48eaff86d ignore families for L2 guard independence 
mike is concerned that we would get too much exposure to adversaries,
if we enforce that none of our L2 guards can be in the same family.

this change set now essentially finishes the feature that commit a77727cdc
was attempting to add, but strips the "_and_family" part of that plan.

7b1fffe0dd make L2 vanguards actually independent 
We had omitted some checks for whether our vanguards (second layer
guards from proposal 333) overlapped or came from the same family.
Now make sure to pick each of them to be independent.

Fixes bug 40639; bugfix on 0.4.7.1-alpha.

8e7bd96362 Fix a check, make a netflow padding function more safe. 
Previously, `channelpadding_get_netflow_inactive_timeout_ms` would
crash with an assertion failure if `low_timeout` was greater than
`high_timeout`. That wasn't possible in practice because of checks
in `channelpadding_update_padding_for_channel`, but it's better not
to have a function whose correctness is this tricky to prove.

Fixes #40645.  Bugfix on 0.3.1.1-alpha.
