- pending_conns removed in favor of direct creation of link::Connection objects in link::Endpoint::{service,client}_conn containers
- conn lookup maps removed, they were pointless
- laying the groundwork for functional client->service node connections. this requires ALPNs verification as a secondary method of identification to the remote key
- refactored btreq stream creation to use improved stream creation logic in libquic
- new btdc method used to ensure no junk at the end of our bt data
- DRYed out the RC code
- check inbound bootstraps against all registered routers, not just whitelist
- libquic vbump
- pending conns container stops them from being counted towards active conns in the interim
- un-abstracted pendingmessages vs pendingdatamessages vs pendingcontrolmessages (gross)
- fixed bootstrap fetching and storage!
`deregister_peer` does the exact same thing as `close_connection` so
just remove it.
Also removes an unnecessary loop dispatch call (because we *have* to be
in the logic thread already to be able to touch the variables we are
touching before the dispatch).
- redoing link_manager functions again to implement previously ignored review comments on several PRs
- conceptually merging "whitelist_routers" and new "known_{rids,rcs}", s.t. we can completely eliminate white/red/gray/green/etc lists in favor of something that isn't dumb
- disable reachability testing with config option; required to be done on testnet
- reachability testing pipeline through link_manager executes pings similar to storage server. connection established hook reports successful reachability, while connection closed callback (with non-default error code) reports unsuccessful testing
- bootstrap cooldown implemented with 1min timer in case all bootstraps fail
- set comparison implemented in non-initial and non-bootstrap rc fetching; set comparison in rid fetching is done every fetch
- nodedb get_random functions refactored into conditional/non-conditional methods. Conditional search implements reservoir sampling for one-pass accumulation of n random rcs
