... that will be used if an icon can't be found in the
current theme.
The Icon Theme Specification
https://standards.freedesktop.org/icon-theme-spec/latest/ar01s05.html
states that unthemed icons must be searched in the base directories,
i.e. /usr/share/icons, ... But in practice unthemed icons are
installed into /usr/share/pixmaps and this dir is not used as
a base dir for icon themes. So it's better to explicitly specify
fallback dirs to avoid needless access to the filesystem.
Also some KDE application install their own unthemed icons
(into /usr/share/<appname>/pics), that can't be found by
QIconLoader. With this change it would be possible for them
to specify dirs with unthemed icons and thus be displayed
correctly in non-KDE environments.
[ChangeLog][QtGui][QIcon] Added fallbackSearchPaths() that
will be used to find icons missing in the current icon theme.

Loading icons is quite slow because we need to stat many files in many directories.
That's why gtk adds a cache in the icon theme directory so it avoids stating lots
of files.
The cache file can be generated with gtk-update-icon-cache utility on a theme
directory. If the cache is not present, corrupted, or outdated, the normal slow lookup
is still run.
[ChangeLog][QtGui][QIcon] fromTheme gained the ability to use the GTK icon cache
to speed up lookups.

This commit fixes incorrect logic of icons' lookup if there are
fallbacks or more than one theme's directory.
According to Icon Theme Specification, Directory Layout section, theme
can be spread across several base directories by having subdirectories
of the same name. This makes possible to extend system themes by
application-specific icons without making of collisions with other
applications.
According to Icon Naming Specification, Icon Naming Guidelines section,
icon name may contain dashes to separate levels of specificity in icon
names. This makes possible to set in application very specific icon
which may be not in every theme. So it can fallback to less specific one.
