"""Test spending coinbase transactions.

|
|
The coinbase transaction in block N can appear in block
|
|
N+100... so is valid in the mempool when the best block
|
|
height is N+99.
|

This test makes sure coinbase spends that will be mature
|

in the next block are accepted into the memory pool,

but less mature coinbase spends are NOT.
