23f4343781 Add CMerkleTx::IsImmatureCoinBase method (Ben Woosley)
Pull request description:
All but one call to `GetBlocksToMaturity` is testing it relative to 0
for the purposes of determining whether the coinbase tx is immature.
In such case, the value greater than 0 implies that the tx is coinbase,
so there is no need to separately test that status.
This names the concept for easy singular use.
