[PATCH 00/24] virstoragetest: Re-instate testing of images without backing format

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' build-aux/syntax-check.mk | 2 +- tests/testutils.c | 30 + tests/testutils.h | 3 + tests/virstoragetest.c | 906 ++++++------------
