9cdda3f7c7 tools: add helpful vector and read operations 
After importing the I/O ops trait via:
    use crate::tools::io::ops::*;

Instead of:
    let mut buffer = vec![0u8; 65536];
    file.read_exact(&mut buffer)?;
use:
    let buffer = file.read_exact_allocated(65536)?;

After importing the vector helpers via:
    use crate::tools::vec::{self, ops::*};

For a buffer which *could* be uninitialized but you prefer
zero-initialization anyway for security reasons, instead of:
    let mut buffer = vec![0u8; len];
use:
    let mut buffer = vec::undefined(len);
which zero-initializes, but, if the `valgrind` feature flag
is enabled, marks the vector as having undefined contents,
so reading from it will cause valgrind errors.

5e5eed5c3b use double-fork for reload 
To ensure the new process' parent is pid 1, so systemd won't
complain about supervising a process it does not own.

Fixes the following log spam on reloads:
Apr 25 10:50:54 deb-dev systemd[1]: proxmox-backup.service: Supervising process 1625 which is not our child. We'll most likely not notice when it exits.

`SIGHUP`, so provide a helper creating the signalfd stream
doing that - this is simply a filtered stream which passes
the remaining signals through, so it can be used exactly
like the signalfd stream could before to add more signals.
