Most of the series are refactors to make virstoragetest less archaic,
the last commit then re-introduces testing of images which don't have
backing format recorded in the metadata which can't be formatted using
qemu-img any more but have security implications if we'd mishandle them.

Peter Krempa (24):
  virstoragetest: Drop testing of RBD backends via parsing real images
  virstoragetest: Drop testing of NBD backends via parsing real images
  testutils: Introduce helper for stripping bulilddir/srcdir from test
    outputs
  virstoragetest: Store output of TEST_CHAIN in output files
  virstoragetest: Remove redundant arguments for chain lookup tests
  virstoragetest: Rework TEST_LOOKUP* cases to work on fake backing
    chain
  virstoragetest: Test backing chain loops with hardcoded images
  virstoragetest: Use existing directory in the source tree for
    'directory' probing tests
  virstoragetest: Use a pre-formatted QED file for testing backing store
    extraction
  virstoragetest: Use pre-formatted file for non-path extraction test
  virstoragetest: Use preformatted file for testing missing backing
    store
  virstoragetest: Use existing file for testing 'raw' image lookup
  virstoragetest: Convert symlink and relative image testing use
    preformatted images
  virstoragetest: Use preformatted qcow2 image for testing relative
    paths
  virstoragetest: Unify testing of QCOW2 images with absolute backing
  virstoragetest: Stop rewriting images in 'mymain'
  virstoragetest: Don't rewrite the 'qcow2' image
  virstoragetest: Assume that 'qemu-img' supports '-o compat='
  virstoragetest: testPrepImages: Don't reuse 'cmd' pointer
  virstoragetest: testPrepImages: Use 'qemu-img' to format 'raw' image
  virstoragetest: testStorageChain: Skip test if filename is NULL
  virstoragetest: Don't skip the whole test when qemu-img fails to
    format images
  virstoragetest: Remove pointless goto from mymain
  virstoragetest: Reinstate testing of images without 'backing_fmt'
