Use MDB_APPEND mode where possible
...
When keys are contiguous and monotonically increasing, this gets
denser page utilization (doesn't leave padding in page splits).
Can't be used for keys that are inserted in random order (e.g. hashes)
In total this only saves around 1.5% of space compared to original
DB code. The previous patch accounted for 0.8% savings on its own;
the blocks tables just aren't that big.

Saves a bit of seek overhead. LMDB frees them automatically

BlockchainLMDB: Deal with DB exceptions at block level with particularity

general use of txn.
