conf: delete internal directory field
Another field no longer needed, getting us one step closer to merging virStorageFileMetadata and virStorageSource. * src/util/virstoragefile.h (_virStorageFileMetadata): Drop field. * src/util/virstoragefile.c (virStorageFileGetMetadataInternal) (virStorageFileGetMetadataFromFDInternal): Alter signature. (virStorageFileFreeMetadata, virStorageFileGetMetadataFromBuf) (virStorageFileGetMetadataFromFD): Adjust clients. * tests/virstoragetest.c (_testFileData, testStorageChain) (mymain): Simplify test.
