This series fixes and improves the 'json:' pseudo-protocol parser and
implements the 'offset' and 'size' attributes and exposes them as
<slice> in the XML.

Peter Krempa (15):
  virStorageSourceParseBackingJSON: Pass around original backing file
    string
  virStorageSourceParseBackingJSON: Move deflattening of json: URIs out
    of recursion
  virStorageSourceJSONDriverParser: annotate 'format' drivers
  virStorageSourceParseBackingJSON: Allow 'json:' pseudo URIs without
    'file' wrapper
  virStorageSourceParseBackingJSON: Prevent arbitrary nesting with
    format drivers
  tests: virstorage: Add test cases for "json:" pseudo-URI without
    'file' wrapper
  tests: virstorage: Add test data for json specified raw image with
    offset/size
  util: virstoragefile: Add data structure for storing storage source
    slices
  qemuBlockStorageSourceGetFormatRawProps: format 'offset' and 'size'
    for slice
  qemuDomainValidateStorageSource: Reject unsupported slices
  docs: formatdomain: Close <source> on one of disk examples
  docs: Document the new <slices> sub-element of disk's <source>
  conf: Implement support for <slices> of disk source
  tests: qemu: Add test data for the new <slice> element
  virStorageSourceParseBackingJSONRaw: Parse 'offset' and 'size'
    attributes
