Close the channels if there is an error so that there's no deadlock
Add a test for the dump with a checksum
Check the RDB version when handling the checksum
Close the channels if there is an error so that there's no deadlock
Complete the test for readVersionNumber
Merge branch 'master' into checksum
Add a io.Reader which computes the CRC64 of the data like Redis does
Do not use a bufio.Reader so that we can keep control on the reading of the data, needed for the checksuming
Complete the test TestDumpWithChecksum
