else it's rather to subtle and not a nice interface considering that
we only want to have a thin wrapper for sd_notify_barrier..

until now, we manually polled the systemd service state during a reload
so that the sd_notify messages get processed in the correct order
(RELOAD(old) -> MAINPID(old) -> READY(new))
with systemd >= 246 there is now 'sd_notify_barrier' which
blocks until systemd processed all prior messages
with that change, the daemon does not need to know the service name anymore

show how to generally start a daemon that serves a rest api + index page
api calls are (prefixed with either /api2/json or /api2/extjs):
/ GET listing
/ping GET returns "pong"
/items GET lists existing items
POST lets user create new items
/items/{id} GET returns the content of a single item
PUT updates an item
DELETE deletes an item
Contains a small dummy user/authinfo

this has a 'from_listener' (tokio::net::TcpListener) since hyper 0.14.5 in
the 'tcp' feature (we use 'full', which includes that; since 0.14.13
it is not behind a feature flag anymore).
this makes it possible to create a hyper server without our
'StaticIncoming' wrapper and thus makes it unnecessary.
The only other thing we have to do is to change the Service impl from
tokio::net::TcpStream to hyper::server::conn::AddStream to fulfill the trait
requirements.

When printing unicode text, a glyph can take up more (or less) space than
a single column. To handle that, use the 'unicode-width' crate which
calculates the width by the unicode standard.
This makes the text tables correctly aligned when printing unicode
characters (e.g. in a datastore/user/syncjob comment).
'unicode-width' is used itself in the rust compiler to format errors
(see e.g. the Cargo.toml in /compiler/rustc_errors of the rust git)
