Simplify the phase 2 code by treating .bad files just like regular chunks, with the exception of stat logging. To facilitate, we need to touch .bad files in phase 1. We only do this under the condition that 1) the original chunk is missing (as before), and 2) the original chunk is still referenced somewhere (since the code lives in the error handler for a failed chunk touch, it only gets called for chunks we expect to be there, i.e. ones that are referenced). Untouched they will then be cleaned up after 24 hours (or after the last longer-running task finishes). Reason 2) is also a fix for .bad files not being cleaned up at all if the original is no longer referenced anywhere (e.g. a user deleting all snapshots after seeing some corrupt chunks appear). cond_touch_path is introduced to touch arbitrary paths in the chunk store with the same logic as touching chunks.

``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 = "git://git.proxmox.com/git/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).
Build
=====
on Debian Buster
Setup:
1. # echo 'deb http://download.proxmox.com/debian/devel/ buster main' >> /etc/apt/sources.list.d/proxmox-devel.list
2. # sudo wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
3. # sudo apt update
4. # sudo apt install devscripts debcargo clang
5. # git clone git://git.proxmox.com/git/proxmox-backup.git
6. # sudo mk-build-deps -ir
Note: 2. may be skipped if you already added the PVE or PBS package repository
You are now able to build using the Makefile or cargo itself.
