The segfaults were happening on GTK icon theme functions, which are
called via the C++ interface functions such as Gtk::IconTheme::has_icon.
There are multiple modules and threads using this functions on the default
icon theme by calling Gtk::IconTheme::get_default(), which returns the same
object for all callers, and was causing concurrent access to the same internal
data structures on the GTK lib. Even a seemingly read-only function such as
has_icon can cause writes due to the internal icon cache being updated.
To avoid this issues, a program wide global mutex must be used to ensure
a single thread is accessing the default icon theme instance.
This commit implements wrappers for the existing IconTheme function calls,
ensuring the global lock is held while calling the underling GTK functions.
`show_all` call from `Tray::update` attempts to walk the widget tree and
make every widget visible. Since we control individual tray item
visibility based on `Status` SNI property, we don't want that to happen.
Modify `Tray::update` to control the visibility of a whole tray module
only and ensure that the children of `Item` are still visible when
necessary.
On the `Passive` value of `Status` tray items would be hidden unless
`show-passive-items` is set to true.
On the `NeedsAttention` value of `Status` tray items will have a
`.needs-attention` CSS class.

It seems that dbusmenu is not ready to display menu immediately and
needs some time to sync data via DBus.
Fixes LIBDBUSMENU-GLIB-CRITICAL: dbusmenu_menuitem_send_about_to_show:
assertion 'DBUSMENU_IS_MENUITEM(mi)' failed.
Also fixes initial render of the menu with layer shell popups support patch.
Set ItemIsMenu to true by default because libappindicator supports
neither ItemIsMenu nor Activate method and compiant SNI implementations
are expected to reset the flag during initial property fetch.
To be revisited if anyone finds the implementation that has Activate
but does not set ItemIsMenu.
