channels: Strictly check the version of '.guix-channel'.
Until now the 'version' field in '.guix-channel' could be omitted, or it could be any value. * guix/channels.scm (read-channel-metadata): Rename to... (channel-instance-metadata): ... this. (channel-instance-dependencies): Adjust accordingly. (read-channel-metadata): New procedure. Use 'match' to require a 'version' field. Provide proper error handling when the channel sexp is malformed or when given an unsupported version number. (read-channel-metadata-from-source): Use 'catch' and 'system-error-errno' instead of 'file-exists?'. * tests/channels.scm (instance--unsupported-version): New variable. (read-channel-metadata): Rename to... (channel-instance-metadata): ... this. Rename tests accordingly. ("channel-instance-metadata rejects unsupported version"): New test.
