The code in menubar.icon_theme naively implements the algorithm from the
base dir specification. This is a problem: On this system,
/usr/share/icons/{Adwaita,hicolor}/index.theme list 91, respectively 649
subdirectories. Since we check for three file extensions (png, svg,
xpm), this means that a failing icon lookup for the Adwaita theme checks
for (91+649)*3 = 2220 files (in practice it might be a bit better since
the directories have specific meanings, but still). That's insane.
Since we only use this code for looking up category icons anyway, just
deprecate this mess. Category icons are now looked up in the same way
that icons for individual applications are looked up.
Since menubar.init does not require("menubar.icon_theme"), this means
that menubar.icon_theme is no longer actually loaded. That's bad.

The return value for this function is used as an index in a table and
Lua does not like nil as an index.
The function that actually looks for icons, find_icon_theme() already
falls back to "hicolor" if it does not find anything via the current
theme, so fix this issue by just falling back to "hicolor" here as well.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

This avoids having to mock half the C API just because all of awful is loaded
needlessly in this unit test and is generally a good idea.

The way of icon path lookup for `menubar` is enhanced so that it is
based on a theme-oriented way as described in the specification:
Icon Theme Specification, Ver. 0.12
http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html
To accomplish this:
* Add the two new files `icon_theme.lua` and `index_theme.lua`.
The former implements an icon lookup algorithm suggested in the URL
above. The latter implements a helper object to parse the cache file
`index.theme` of which data is used by the former.
* Modify `menu_gen.lua` to use the new algorithm.
- The implementation of `lookup_category_icons` is changed
accordingly.
- The values of the field `all_categories.icon_name` are changed file
names to icon names, i.e., file extensions which are used to
indicate image file formats are removed.
* Add the new file `icon_theme_spec.lua` for a unit test for checking
if `icon_theme.lua` together with `index_theme.lua` works as
expected.
