b2f1c58805 Use cursors in some remove functions
Helps when they're called repeatedly in one txn

118dd69dd5 Use DUPFIXED for block_info and output_txs
Saves another ~150MB or so on the full blockchain

6225716f3c More outputs consolidation
Also bumped DB VERSION to 1
Another significant speedup and space savings:
Get rid of global_output_indices, remove indirection from output to keys

This is the change warptangent described on irc but never got to finish.

7c5abdc3a3 Use DUPFIXED for output_keys
Saves another 90MB on 200000 block import.
Had to bring back compare_uint64 for this, but it's safe since
this table is always 64-bit aligned.

132c666f67 Update schema for "tx_outputs" to use array containing amount output indices
This speeds up wallet refresh by directly retrieving a tx's amount output indices.

It removes the indirection and walking the amount output duplicate list
for every amount in each requested tx.

"tx_outputs" is used by:
Amount output indices are needed for wallet refresh.
Global output indices are needed for removing a tx.

Both amount output indices and global output indices are now stored in
an array of 64-bit unsigned ints:

tx_outputs[<tx_hash>] -> [ <a1_oi, a1_gi, a2_oi, a2_gi, ...> ]

Previously it was:
tx_outputs[<tx_hash>] -> duplicate list of <a1_gi, a2_gi, a3_gi, ...>

The amount output list had to be walked for every amount in order to
find each amount's output index, by comparing the amount's global output
index with each one in the duplicate list until a match was found.

f2faf8cdd9 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.

090b548c3b Use cursors in write txns
Saves a bit of seek overhead. LMDB frees them automatically
in txn_(commit|abort) so they need no cleanup.

BlockchainLMDB: Deal with DB exceptions at block level with particularity
Add another DB error exception type to distinguish failed txn setup from
general use of txn.

This keeps the error handling flow the same as before the block-level
txn setup changes that moved control up a layer to BlockchainDB.
