Detailed Description

The XMP-sidecar half of what used to be common/exif.cc.

Cut out of a 4775-line translation unit that was doing two unrelated jobs. This one serialises the development – history stack, mask shapes, module order – into and out of the XMP document; the other, the photograph's own tags, is metadata/exif.cc. See common/xmp_sidecar.h, including why this is not in src/metadata.

Read an XMP packet off disk into packet, FALSE if the file cannot be read.

Exiv2::readFile() would do this, but only through exiv2's own path handling – which is exactly the capability 0.28 dropped on Windows (see WIDEN() in metadata/exif_internal.h). These are small sidecar files and Ansel already has a reader that goes through g_fopen(), so there is no reason to route them back out through exiv2 and depend on something it may not be able to do. It also drops the 0.27-vs-0.28 fork over DataBuf's members that each of those call sites carried.
