Banff.6 - Dynamic State Syncing Support

This version is backwards compatible to v1.9.0. It is optional, but encouraged. The supported plugin version is 22.

Consensus

• Added StateSyncMode to the return of StateSummary#Accept to support syncing chain state while tracking the chain as a light client
• Added AcceptedFrontier to Chits messages
• Reduced unnecessary confidence resets during consensus by applying AcceptedFrontiers during QueryFailed handling
• Added EngineType for consensus messages in the p2p message definitions
• Updated vertex.DAGVM interface to support linearization

Configs

• Added --plugin-dir flag. The default value is [DATADIR]/plugins
• Removed --build-dir flag. The location of the avalanchego binary is no longer considered when looking for the plugins directory. Subnet maintainers should ensure that their node is able to properly discover plugins, as the default location is likely changed. See --plugin-dir
• Changed the default value of --api-keystore-enabled to false
• Added --track-subnets flag as a replacement of --whitelisted-subnets

• Fixed NAT-PMP router discovery and port mapping
• Fixed --staking-enabled=false setting to correctly start subnet chains and report healthy
• Fixed message logging in the consensus handler

VMs

• Populated non-trivial logger in the rpcchainvm Server's snow.Context
• Updated rpcchainvm proto definitions to use enums
• Added Block format and definition to the AVM
