* p2p/dnsdisc: add support for enode.Iterator
This changes the dnsdisc.Client API to support the enode.Iterator
interface.
* p2p/dnsdisc: rate-limit DNS requests
* p2p/dnsdisc: preserve linked trees across root updates
This improves the way links are handled when the link root changes.
Previously, sync would simply remove all links from the current tree and
garbage-collect all unreachable trees before syncing the new list of
links.
This behavior isn't great in certain cases: Consider a structure where
trees A, B, and C reference each other and D links to A. If D's link
root changed, the sync code would first remove trees A, B and C, only to
re-sync them later when the link to A was found again.
The fix for this problem is to track the current set of links in each
clientTree and removing old links only AFTER all links are synced.
* p2p/dnsdisc: deflake iterator test
* cmd/devp2p: adapt dnsClient to new p2p/dnsdisc API
* p2p/dnsdisc: tiny comment fix
This change:
- removes the PostChainEvents method on core.BlockChain.
- sorts 'removed log' events by block number.
- fire the NewChainHead event if we inject a canonical block into the chain
even if the entire insertion is not successful.
- guarantees correct event ordering in all cases.
The original idea behind this change was to remove a use of the
deprecated CancelRequest method. Simply removing it would've been an
option, but I couldn't resist and did a bit of a refactoring instead.
All remote sealing code was contained in a single giant function. Remote
sealing is now extracted into its own object, remoteSealer.
