The genesis blocks are not really part of the wire protocol rather they are part of a network parameters. Thus, this commit moves the all of the gensis blocks and tests to the btcnet package. Also, create variables in the test package for the mainnet genesis hash, merkle root, and coinbase transaction for use throughout the tests since they the exported values are no longer available.
