In rare circumstances, we may fork(), e.g., as part of a custom module,
and the child process may fail to exec() and exit. In those cases, the
IPC destructor will be called in the child process.
Prior to this commit, this call would then result in the shared socket
being closed. Prevent this by only closing the socket from the original
process.
Fixes#3975 and #4152.

1. Fix warnings reported by clang tidy
2. Use unique lock instead of manully lock/unlock on mutex.
The RAII style locking makes sure mutex is unlocked when exceptions are thrown
The AButton class is designed as full a substitute to ALabel. The
GtkButton attribute 'button_' is initialized with a label. This
label can the be referenced by the subsequent inheritors of AButton
instead of the GtkLabel attribute 'label_' of ALabel.
For convenience a GtkLabel* 'label_' attribute is added to AButton.
If the button cannot be clicked it is disabled, effectively acting
like its label predecessor.
GtkButton seems to catch one-click mouse events regardless of the
flags set on it. Therefore, 'signal_pressed' is connected to a
function creating a fake GdkEventButton* and calling 'handleToggle'
(for details on this possible bug in GTK see:
https://stackoverflow.com/questions/45334911 )
In accordance with other GtkButtons (i.e. the sway/workspace ones)
set_relief(Gtk::RELIEF_NONE) is called on the 'button_' instance.
