Protect desirable or disadvantaged inbound peers from eviction by ratio.
This function protects half of the peers which have been connected the longest, to replicate the non-eviction implicit behavior and preclude attacks that start later.
Half of these protected spots (1/4 of the total) are reserved for the following categories of peers, sorted by longest uptime, even if they're not longest uptime overall:
- onion peers connected via our tor control service
- localhost peers, as manually configured hidden services not using
-bind=addr[:port]=onion
will not be detected as inbound onion connections
- I2P peers
This helps protect these privacy network peers, which tend to be otherwise disadvantaged under our eviction criteria for their higher min ping times relative to IPv4/IPv6 peers, and favorise the diversity of peer connections.

Select an inbound peer to evict after filtering out (protecting) peers having distinct, difficult-to-forge characteristics.
The protection logic picks out fixed numbers of desirable peers per various criteria, followed by (mostly) ratios of desirable or disadvantaged peers. If any eviction candidates remain, the selection logic chooses a peer to evict.

How long to delay before querying DNS seeds.
If we have more than THRESHOLD entries in addrman, then it's likely that we got those addresses from having previously connected to the P2P network, and that we'll be able to successfully reconnect to the P2P network via contacting one of them. So if that's the case, spend a little longer trying to connect to known peers before querying the DNS seeds.
