This enables the app to use the dark theme when running in environments
where a dark theme is available.
This is not done in Windows because the dark theme looks quite odd when
run on older versions of Windows where GTK can't replace the titlebars
by default.

The header bar includes space for both a title and subtitle. By using
the latter for the ungrab hint, we avoid having such a long title.

The user interface for the fullscreen toolbar is now identical to that
seen when non-fullscreen. All that differs is that the toolbar autohides
in fullscreen mode and doesn't expand to fill the window width.
There is a complication with the timed revealer and menus. With
traditional GtkMenus, it appears a grab is held as long as the menu is
open, so the revealer won't hide the toolbar. With modern GtkPopover
based menus, however, the revealer hides the toolbar despite the menu
being open, and thus in turn hides the menu.
This hacks around the problem by setting the header buttons to force use
of a traditional GtkMenu instead of a GtkPopover. It is not quite as
visually pretty, but at least it works.

This removes the main menu bar in favour of using the GtkHeaderBar with
integrated bars. This reduces the amount of vertical screen real estate
consumed by the application, leaving more for the guest display. The new
buttons are laid out to make the more common actions available with a
single click.
The buttons are grouped into two sets. On the left hand side of the
header are buttons that are interacting with the server
- Send key
- USB device selection
- Monitor selection and VM pause/shutdown
whle on the right hand side are buttons interacting with the local user
interface
- Fullscreen
- Preferences / About / Guest detail / zoom level

The machine pause/reset/powerdown and smartcard insert/remove operations
can implemented directly by the application class as they require no UI.

The first time this method is called we know that
usb_device_reset_accel_valid will be FALSE.
The other times this method is called all pass override=TRUE.
Thus the conditional test in virt_viewer_set_usb_device_reset_accel
always evaluates to TRUE and thus can be removed.

If the VncDisplay emits a signal and the VirtViewerSessionVnc
instance is no longer valid, using the pointer inside one of the
callbacks can lead to segfault.
To prevent that, use g_signal_connect_object instead of
g_signal_connect.

This partially reverts commit de5cd71.
Problem with that commit is, that it practically renders
the "session-auth-*" signals from vnc session useless.
That's because gtk-vnc currently emits "vnc-error" before each
"vnc-auth-*" signal and the error callback in virt-viewer-app.c
calls virt_viewer_app_disconnected(), which in turn closes
the session.
As a consequence, virt-viewer never retries authentication
with vnc, it simply exits.
Since the last commit, vnc, similarly to spice, emits
"session-disconnected" with the appropriate error message. Thus
there's no need to maintain separate "session-error" signal
for now.
With vnc, this error message is shown to the user in a dialog,
if the disconnect happened during the init phase.
"session-auth-*" callbacks create their own dialogs, so
initialized must be set to TRUE to avoid having a dialog
displayed twice.

"vnc-error" is always followed by "vnc-disconnected".
So save the error message and use it in "vnc-disconnected" callback.
"session-disconnected" already allows us to set a string
with details on why the disconnection happened.
This approach is also similar to the one in spice session
(GError is saved in virt_viewer_session_spice_channel_destroyed).

Instead of repeating an emacs footer in every source file, use config
files in the root of the repository. This fixes the bug that several
source files are missing the indent rules.

All our targetted distros have this vintage glib letting us remove some
compat code, and introduce future use of new features.
