Fixes#671
Unexpose GenesisDoc and ChainID fields to avoid them being
serialized to the DB on every block write/state.Save()
A GenesisDoc can now be alternatively written to the state's
database, by serializing its JSON as a value of key "genesis-doc".
There are now accessors and a setter for these attributes:
- state.GenesisDoc() (*types.GenesisDoc, error)
- state.ChainID() (string, error)
- state.SetGenesisDoc(*types.GenesisDoc)
This is a breaking change since it changes how the state's
serialization and requires that if loading the GenesisDoc entirely
from the database, you'll need to set its value in the database
as the GenesisDoc's JSON marshaled bytes.

Replaces #540
If a peer requests a block with a height that we don't have
respond with a bcNoBlockResponseMessage.
However, according to the Tendermint spec, if all nodes are honest
this condition shouldn't occur, so this is a possible hint of an
dishonest node.

- move txindexer to state
- fix type
save Tx Index as well
do not store tx itself in the result
