The only action we need is to stop loading.

The code to cleanup actions relies on GtkContainer API, gone in GTK4.

So, specialize the code on the stop button.

The traditional include guards are not as easy to handle
and require extra thought into the names.

Pragma once is an easier, more contributor friendly approach.

general: Remove include guards in favor of pragma once

Porting Nautilus object declarations to G_DECLARE_*_TYPE will
reduce a huge number of boilerplate code.

That will make nautilus code easier for newcomers and others alike.

Due to the floating bar being in an overlay, it can obscure the content
under it.

We were planning to remove it and use an action bar. But it's taking
long, so in the meantime we can improve this situations hiding the
floating bar when hovered.

On the way I improved the handling of the spinner, which was failing
to be shown on certain situations.

Patch based on Nelson Benitez, thanks!

Vim and emacs modelines are used to specify some of the code style in the code.
However, this is misleading and poorly supported since nautilus had a mix of
code style for some time.
Also, the mode lines doesn't specify the whole code style, so we will need to
use a different tool as well to specify the whole code style.
For that, we can just use a different tool for everything.

So remove the mode lines, and in a short future we will reestyle the nautilus
code to have a single code style, and use a tool like editorconfig to specify
the whole code style.

There's another occurrence of GtkImageMenuItem right now, for the "Open
With..." menu which is harder to fix.

This patch does three things:
- It adds API to the floating bar to have primary and details labels
  instead of a single label. The primary label is ellipsized separately
  from the details, so it makes a good fit for a filename.
- Modifies the code setting status messages in NautilusView to split
  them into two separate strings
- Removes obsolete code in NautilusView and NautilusWindowSlot that was
  setting long statuses for the old non-floating statusbar

- add dialog-like actions
- add show/hide spinner
