icon-container: Fix the build with self tests disabled
places-sidebar: disallow context menus for sidebar headings

We already make them non-selectable - there's no point in having a menu
for headings here.

x-content-bar: pack the media label in the content area

Instead of just packing it into the GtkInfoBar's box, since that will
put it after the buttons of the action area.

file: don't automatically prepend a note emblem for annotated files

Since we don't support editing notes in the UI anymore, it doesn't make
sense to display a note emblem when the file is annotated.
file: remove dead code

TRASH_FAST_ENOUGH is never defined
all: compute emblem names to ignore automatically

Consolidate identical code that builds a list of emblems to ignore
inside nautilus_file_get_emblem_icons()
file: make nautilus_file_get_keywords() private

No need to export this, since the only caller is inside nautilus-file.c
file: add note to the list of excluded metadata emblems

This also slightly changes the behavior for emblems added by an
extension: before the patch they were subject to the same exclusion
list of metadata keywords. Now they are added unconditionally, since we
assume an extension knows better and will always want the emblem list it
sets properly displayed.
window-manage-views: don't call methods on a NULL NautilusFile

In got_file_info_for_view_selection_callback(), we unconditionally try
to fetch information for the parent directory in case the selection is a
regular file, but we should avoid doing that when the file has no
parent, such as when it's the root of a web server.

Add a way to create a new directory from a selection

Simplify the label text for the new folder and document items

Create is really the understood verb here I think. Having a shorter
label makes it easier to read and more easily accommodates the
longer new folder with selection action.

cluebars: use GTK_MESSAGE_QUESTION for nautilus' cluebars

This removes the need of a separate style for them in the theme.
