blockchain/indexers: Allow interrupts.
This propagates the interrupt channel through to blockchain and the
indexers so that it is possible to interrupt long-running operations
such as catching up indexes.

blockchain: Refactor to use new chain view.
- Remove inMainChain from block nodes since that can now be efficiently
  determined by using the chain view
- Track the best chain via a chain view instead of a single block node
  - Use the tip of the best chain view everywhere bestNode was used
  - Update chain view tip instead of updating best node
- Change reorg logic to use more efficient chain view fork finding logic
- Change block locator code over to use more efficient chain view logic
  - Remove now unused block-index-based block locator code
  - Move BlockLocator definition to chain.go
  - Move BlockLocatorFromHash and LatestBlockLocator to chain.go
    - Update both to use more efficient chain view logic
- Rework IsCheckpointCandidate to use block index and chain view
- Optimize MainChainHasBlock to use chain view instead of hitting db
  - Move to chain.go since it no longer involves database I/O
  - Removed error return since it can no longer fail
- Optimize BlockHeightByHash to use chain view instead of hitting db
  - Move to chain.go since it no longer involves database I/O
  - Removed error return since it can no longer fail
- Optimize BlockHashByHeight to use chain view instead of hitting db
  - Move to chain.go since it no longer involves database I/O
  - Removed error return since it can no longer fail
- Optimize HeightRange to use chain view instead of hitting db
  - Move to chain.go since it no longer involves database I/O
- Optimize BlockByHeight to use chain view for main chain check
- Optimize BlockByHash to use chain view for main chain check

multi: Update markdown files for GFM changes.
The github markdown interpreter has been changed such that it no longer
allows spaces in between the brackets and parenthesis of links and now
requires a newline in between anchors and other formatting.  This
updates all of the markdown files accordingly.

While here, it also corrects a couple of inconsistencies in some of the
README.md files.

bd4e64d1d4 chainhash: Abstract hash logic to new package. (#729)
This is mostly a backport of some of the same modifications made in
Decred along with a few additional things cleaned up.  In particular,
this updates the code to make use of the new chainhash package.

Also, since this required API changes anyways and the hash algorithm is
no longer tied specifically to SHA, all other functions throughout the
code base which had "Sha" in their name have been changed to Hash so
they are not incorrectly implying the hash algorithm.

The following is an overview of the changes:

- Remove the wire.ShaHash type
- Update all references to wire.ShaHash to the new chainhash.Hash type
- Rename the following functions and update all references:
  - wire.BlockHeader.BlockSha -> BlockHash
  - wire.MsgBlock.BlockSha -> BlockHash
  - wire.MsgBlock.TxShas -> TxHashes
  - wire.MsgTx.TxSha -> TxHash
  - blockchain.ShaHashToBig -> HashToBig
  - peer.ShaFunc -> peer.HashFunc
- Rename all variables that included sha in their name to include hash
  instead
- Update for function name changes in other dependent packages such as
  btcutil
- Update copyright dates on all modified files
- Update glide.lock file to use the required version of btcutil

7c174620f7 indexers: Implement optional tx/address indexes.
This introduces a new indexing infrastructure for supporting optional
indexes using the new database and blockchain infrastructure along with
two concrete indexer implementations which provide both a
transaction-by-hash and a transaction-by-address index.

The new infrastructure is mostly separated into a package named indexers
which is housed under the blockchain package.  In order to support this,
a new interface named IndexManager has been introduced in the blockchain
package which provides methods to be notified when the chain has been
initialized and when blocks are connected and disconnected from the main
chain.  A concrete implementation of an index manager is provided by the
new indexers package.

The new indexers package also provides a new interface named Indexer
which allows the index manager to manage concrete index implementations
which conform to the interface.

The following is high level overview of the main index infrastructure
changes:

- Define a new IndexManager interface in the blockchain package and
  modify the package to make use of the interface when specified
- Create a new indexers package
  - Provides an Index interface which allows concrete indexes to plugin
    to an index manager
  - Provides a concrete IndexManager implementation
    - Handles the lifecycle of all indexes it manages
    - Tracks the index tips
    - Handles catching up disabled indexes that have been reenabled
    - Handles reorgs while the index was disabled
    - Invokes the appropriate methods for all managed indexes to allow
      them to index and deindex the blocks and transactions
  - Implement a transaction-by-hash index
    - Makes use of internal block IDs to save a significant amount of
      space and indexing costs over the old transaction index format
  - Implement a transaction-by-address index
    - Makes use of a leveling scheme in order to provide a good tradeoff
      between space required and indexing costs
- Supports enabling and disabling indexes at will
- Support the ability to drop indexes if they are no longer desired

The following is an overview of the btcd changes:

- Add a new index logging subsystem
- Add new options --txindex and --addrindex in order to enable the
  optional indexes
  - NOTE: The transaction index will automatically be enabled when the
    address index is enabled because it depends on it
- Add new options --droptxindex and --dropaddrindex to allow the indexes
  to be removed
  - NOTE: The address index will also be removed when the transaction
    index is dropped because it depends on it
- Update getrawtransactions RPC to make use of the transaction index
- Reimplement the searchrawtransaction RPC that makes use of the address
  index
- Update sample-btcd.conf to include sample usage for the new optional
  index flags
