We can now use iter::from_fn() which makes for a much nicer
logic. The only thing better is going to be when we can use
generators with `yield`.

To make a future cancellable, use:
let (future, canceller) =
crate::tools::futures::cancellable(future);
Proceed with using `future` as usual, `canceller` is
clonable and can cancel the future via the `.cancel()`
method.

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.

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:

Now that we let hyper shutdown gracefully we need an owned

Reloadable resources are now 'Reloadable' instead of

The struct handling the reload is a 'Reloader', not a

Proxy and daemon for now just want to handle reload via
`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.

If the listening socket goes into some error state we'll get
std::io::Errors rather than higher level errors from the
native_tls::TlsAcceptor, those are usually fatal. (Ran into
this after performing a shutdown() on the file descriptor,
after which the future just endlessly loops in accept().)

We want to be able to iterate through digests of index
files, but without always having to distinguish between
dynamic and fixed types, so add a trait we can use as a
trait object.
Unfortunately the iterator needs to yield copies as
iterators cannot yield values with life times when
represented as trait objects (Box<dyn Iterator<Item = ?>>)

The protocol handler will receive chunk data plus a hash
pre-calculated by the client. It will verify the hash before
sending it up to the datastore in order to respond to the
client with an error on a mismatch, so there's no need to
recalculate the hash another time.

It now supports custom conversation methods, so instead of
new() we ask for a default authenticator taking a password
via with_password(). Since the password is now handled by
the now separate conversation handler, `set_credentials()`
is now called on the handler we get via `.get_handler()`.
