Make `flistxattr()` return a `ListXAttr` helper which provides an iterator over `&CStr`. This exposes the property that xattr names are a zero-terminated string without simply being an opaque "byte vector". Using &[u8] as a type here is too lax. Also let `fgetxattr` take a `CStr`. While this may be a burden on the caller, we usually already have zero-terminated strings on the call site. Currently we only use this method coming from `flistxattr` after all.

``rustup`` Toolchain
====================
We normally want to build with the ``rustc`` Debian package. To do that
you can set the following ``rustup`` configuration:
# rustup toolchain link system /usr
# rustup default system
Versioning of proxmox helper crates
===================================
To use current git master code of the proxmox* helper crates, add::
git = "ssh://gitolite3@proxdev.maurer-it.com/rust/proxmox"
or::
path = "../proxmox/proxmox"
to the proxmox dependency, and update the version to reflect the current,
pre-release version number (e.g., "0.1.1-dev.1" instead of "0.1.0").
Local cargo config
==================
This repository ships with a ``.cargo/config`` that replaces the crates.io
registry with packaged crates located in ``/usr/share/cargo/registry``.
A similar config is also applied building with dh_cargo. Cargo.lock needs to be
deleted when switching between packaged crates and crates.io, since the
checksums are not compatible.
To reference new dependencies (or updated versions) that are not yet packaged,
the dependency needs to point directly to a path or git source (e.g., see
example for proxmox crate above).
