gexiv2-sys 1.4.0

This crate provides Rust FFI declarations for the gexiv2 library, which is a GObject-based wrapper around Exiv2, which provides read and write access to the Exif, XMP, and IPTC metadata in media files. Only FFI declarations are provided here; for a usable Rust library, consider the `rexiv2` crate.
