* use std::source_location instead of godawful macros in logging
* remove unused/absolutely haram af json logstream
* fix bug in android logger where it doesn't respect eLogNone
before when we get the list of router ids for gossip it was highly bias towards outbound sessions.
instead now we get a full list of link session router ids in random order, truncate them to be at most MaxGossipPeers number of keys, and then put them into an unordered set
* make it so that we don't set up unbound resolver when we have no resolvers provided by config
* clean up dns codepath and make it use llarp::SockAddr instead of llarp::IpAddress
* add remove_node_from_failing to remove a node by pubkey from the failing set
* if a router is deregistered we remove it from the failing set so we don't retest it
* remove a router from the failing set if we get a test success
currently creating an outbound session will cancel if we have any session
at all with the relay. instead, only cancel if we have an outbound session
to that relay. this is useful for reachability testing.
* immediately poke routes when we are told to use an exit so that packets get pushed which makes an exit path happen
* fix up cmake oddity in nsis section
* not gossip our rc
* not explore the network to prevent outbound session attempts
* not establish sessions to other service nodes
* close all open sessions we have to tell clients we don't want them
* catch exceptions flushing peerdb in disk thread
* don't connect out to non allowed routers
* simplify logic in RCLookupHandler::RemoteIsAllowed()
* add HaveReceivedWhitelist to I_RCLookupHandler base type
* add LooksDeregistered to Router type that tells us if we think we are deregistered
* don't allow building paths over us if we are deregistered
Fixes a subtle memory leak that was a result of outbound messages which
were in the shared queue (not yet sorted into a per-path queue) when a
path was removed, resulting in a ghost path queue (and thus round-robin
order entry as well).
Adds much needed documentation to the outbound message handler class.
Wires up systemd support to configure DNS on startup and when
enabling/disabling exit mode.
On startup (and when turning off an exit) we tell systemd-resolved to
direct .loki and .snode lookups to lokinet (leaving other DNS traffic
alone).
On exit enabling, we reconfigure it to resolve "." (i.e. the root DNS
domain) so that all lookups come into it.
* add srv records in RCs if we have any
* add mechanism to add SRV records for plainquic exposed ports
* resign and republish rc or introset on srv record changes
