- Write indexer state and index atomically.
- Simplify chain state with current height.
- Roll forward to best height.
- Synchronize the index with the chain with common method `sync` for
the events 'connect', 'disconnect' and 'reset'. This will prevent
any of the events from conflicting with each other.
- Fix the chain rollback and reset.
- Make sure blocks are connected in the correct order.
- Improve logging to log similar to chain.
module indexer introduces a extensible architecture for indexing the
chain. It provides a base class which handles syncing with the chain,
handling re-orgs, interruptions, dynamic toggling, etc. TXIndexer
and AddrIndexer are provided for indexing transactions and addresses,
using the same flags as before i.e --index-tx and --index-address.
Indexes are stored in a different database and can be maintained
independently of the chain.
This has been patched in both bitcoind and btcd around February 20th, 2014. It was
shortly followed by a headers-first synchronization of blocks.

This commit simply adds an enforce line to check that the height being
requested to reset to is below the chain tip. This way we return a bad
request error rather than a internal server error.
There is potential for around a 10% to 23% increase to the performance
of block reads by using `allocUnsafe`, however there is already around
a 3 to 6 times increase to the performance. While it's safe to use
`allocUnsafe` as the number of bytes read is checked to be the same
size as the buffer allocation, there is a potential for test cases
to introduce _other_ behavior for `fs.read` that may not have the
same behavior, though this isn't currently the case.
update the rpc command to better match bitcoind.
add the ismine and iswatchonly fields and
segwit related fields such as witness_version
and witness_program.
