c401247af9 [syncmgr]
- refactor syncmgr for blockpool
- add nextBlockIndex so that we can add blocks to the blockPool by
comparing their index
- add processBlock helper method,wraps around cfg.ProcessBlock and increments the nextBlockIndex
internally

[PeerMgr] Add Caching and Re-processing system (#263)
[peermgr]

- Add request cache with tests
- Add requestCache to peermgr
- refactored peer manager tests
- Added blockInfo struct, to allow sorting on the blockIndex
- added helper methods for cache, pickItem, pickFirstItem, removeHash,
findHash and refactored tests
- renamed requestcache to blockcache
- refactored peer manager to use block cache for block requests *only*
- added blockCallPeer function to handle block requests only
- refactored onDisconnect to add back any pending peer requests that the
disconnected peer did not complete into the peer manager queue

[peermgr/server]

- Modify onBlock handler in server, to send peermgr a BlockInfo struct

[peermgr/syncmgr/server]

- Modified blockIndex in BlockInfo to be uint32 and not uint64
- RequestBlocks in syncmgr now takes an index along with the hash
- modified syncmgr code to pass index along with hash in all methods

[chain] Refactor, add chaincfg and database initialisation (#243)
* [chain]

- Add basic chain cfg parameters

- Added logic to insert genesis block, if it is a fresh database

- changed SaveBlock to ProcessBlock

Add Chain saving functionality to Database (#206)
* [database]

- Add Prefix method to interface
- Convert leveldb error to `database error`
- Be explicit with prefixedKey in `Table` as slices can be pointers

* [protocol]
- Add stringer method to protocol

* [Chaindb]

- Added saveBlock() which will allow us to save a block into the
database. The block is broken up into transactions and Headers. The
headers are saved as is. The transactions are saved as is, then the
utxos in the transactions are collected to make the utxo db.

- Verification for blocks and transactions will reside in the same
package. Note that the save methods are all unexported, while the Get
methods are exported. Making it so that any can call a get method, but
only code in this package may save to the database. The other code which
will reside in this package will be code verification logic.

* [chaindb]

- Added saveHeader function which saveHeaders  uses

- Update the latest header, each time we save a header instead of after a batch. This is so that we can call saveHeader without saveHeaders. This functionality can be rolled back if the performance of updating the header after a batch is significant

- small refactor in test code
