`NODE_BLOOM` service bit
------------------------
Support for the `NODE_BLOOM` service bit, as described in [BIP
111](https://github.com/bitcoin/bips/blob/master/bip-0111.mediawiki), has been
added to the P2P protocol code.
BIP 111 defines a service bit to allow peers to advertise that they support
bloom filters (such as used by SPV clients) explicitly. It also bumps the protocol
version to allow peers to identify old nodes which allow bloom filtering of the
connection despite lacking the new service bit.
In this version, it is only enforced for peers that send protocol versions
`>=170004` . For the next major version it is planned that this restriction will be
removed. It is recommended to update SPV clients to check for the `NODE_BLOOM`
service bit for nodes that report versions newer than 170004.
