This implements a new voting agenda for the testnet and simnet networks for increasing the maximum block size from 1MiB to 1.25MB. The following is an overview of the changes: - Bump the maximum protocol block size limit to 1.25MB - Bump the protocol version to 4 - Add wire tests for v3 protocol sizes and update tests for latest - Update all wire values that are defined in terms of the max block size to respect the protocol version - Update the MaxSigOpsPerBlock constant to maintain existing value regardless of the raised max protocol block size - Decouple the maximum tx size from the block size by creating a chain parameter for it with the current sizes so it is not a part of the hard fork vote - Add definition for new version 4 stake vote along with agenda to vote on block size to the testnet and simnet networks - Convert the MaximumBlockSize chain parameter to a slice in order to hold the different possible sizes - Adds a new function that returns the maximum block size based upon the result of the vote - Change the existing context-free block size check to enforce the max protocol size and introduce a context-specific check which enforces a restricted size based upon the network consensus parameters and the result of the vote - Set the max allowed size in generated block templates based upon the network params and result of the vote - Generate version 4 blocks and reject version 3 blocks after a super majority has been reached
