Add protocol message compression support:

Browse Source 
* Peers negotiate compression via HTTP Header "X-Offer-Compression: lz4"
* Messages greater than 70 bytes and protocol type messages MANIFESTS,
  ENDPOINTS, TRANSACTION, GET_LEDGER, LEDGER_DATA, GET_OBJECT,
  and VALIDATORLIST are compressed
* If the compressed message is larger than the uncompressed message
  then the uncompressed message is sent
* Compression flag and the compression algorithm type are included
  in the message header
* Only LZ4 block compression is currently supported
