net: increase inbound capacity for block-relay-only connections

Browse Source 
..and adjust the eviction logic.
The new default max connection number is 200, the default maximum of tx-relaying
inbounds is limited to 50% of all inbound connections.
With 11 outbound connections, that is (200 - 11) * 0.5 = 94.5.
As a result, the tx-related maximum traffic should not change
drastically.

When we receive an inbound connection and don't have space for another
full-relay peer, we now attempt to evict specifically a full-relay inbound
after receiving the version message of the new peer.

Once this commit is widely deployed, the added inbound capacity will
allow us to increase the number of outgoing block-relay-only connections.
