This changes makes svg icons go through the same scale calculation
code as png icons. As a consequence, an svg that is put into the
32x32 directory will actually be loaded at size 32, even if it
gets requested at a bigger size. This will let us avoid giant
spinners.

Add two new icon lookup flags, GTK_ICON_LOOKUP_DIR_LTR and _RTL,
which tell GtkIconTheme to look for icon variants which have a
-ltr or -rtl suffix. GtkIconHelper adds these lookup flags when
looking up icons.
Note that due to the way this overlaps with symbolic icon lookup,
directional variants of symbolic icons must be called -symbolic-rtl, not
-rtl-symbolic.

When forcing regular or symbolic icons, fall back to the default
specified icons. This ensures that when no symbolic icon is present, an
icon will still appear - the regular one.
GTK_ICON_LOOKUP_FORCE_REGULAR and GTK_ICON_LOOKUP_FORCE_SYMBOLIC can be
used to force a regular or symbolic icon to be loaded, even if the icon
names specify a different version.
This is intended to support the CSS property -gtk-icon-style.
Commit faba7df4fe changed the logic in
apply_emblems() so that GtkIconInfo->emblems_applied would be set to
TRUE even in case there was no emblem info available, which confuses the
theme cache.
This commit changes the logic back, so that NULL is returned from
apply_emblems_to_pixbuf() when there are no emblems available, fixing
the bug.

This is what we used to get through the Net/FallbackIcontheme
setting. Nobody has ever set this setting to a different value,
and people have come to rely on GTK+ applications getting their
icons this way.
When doing fallback for symbolic icons, we first shorten
the name at dashes while preserving the -symbolic suffix.
But after exhausting that, we should also try stripping
the suffix.

When loading a symbolic icon, g_file_get_contents() is currently used
with the icon pathname, to load its SVG data. This won't work when the
icon is not a local file, for instance when a symbolic icon is loaded
from a GFileIcon with a GResource path.
Fortunately GtkIconInfo already holds a GFile, so we can just use
g_file_load_contents() to load the data instead.

If an icon is in a Fixed or Threshold directory we normally don't
scale it. However, in the case of HiDPI scaling we *do* want to
scale it, to avoid different layouts in Lo/HiDPI. We look up whatever
the size of the icon would have been in LoDPI and scale to that
in the no-scaling case, thus getting the same layout as the
unscaled case.

GdkPixbuf will fail returning %NULL if we try to scale a pixbuf to (0, 0),
which will then trigger an assertion in gtk_icon_info_load_icon_finish();
we never want a scale of 0, so ensure it is at least 1.
