This GIO extension should make it easier to get values for an application
from the corresponding desktop file (typically `G_KEY_FILE_DESKTOP_KEY_NAME`
or `G_KEY_FILE_DESKTOP_KEY_ICON`).
At its first try, `xfce_g_desktop_app_get_value` will look for
`$application_name.desktop` and then return the respective key.
If no such desktop file is found, it will leverage GIO's
`g_desktop_app_info_search` to match a desktop file and then return
the values from that.

If no desktop file is found at all, the function returns `NULL`.

This function can be used by Xfce applications to match application name
and icon when only incomplete information is available.

If I'm not mistaken this check is not really necessary, i.e. these
warnings are false positives. However, the code of `simple_parse_line()`
is at least not clear enough to make this clear, so it's better to add
it.

Migrated useful functions from exo-string

Functions
xfce_str_replace  : Find and replace substring

Macros
xfce_str_is_empty : Check if a string is either empty or NULL
I_                : Abbreviation for g_intern_static_string

This patch removes all custom gettext macro definitions. There are multiple
issues with these macros:

- They are redundant: gettext functions are already declared in <libintl.h>
- The implementations of the ngettext macros are invalid
- If an Xfce GUI app or plugin accidentally uses any of the gettext macros
  defined in xfce-i18n.h, then it completely disables localication in the
  app or plugin

The file <libintl.h> containing the declaration of gettext() has been
included by both <gi18n.h> and <gi18n-lib.h> since year 2008 (at least).

The removal also resolves the following warning messages:

Adding GIO to gir_INCLUDES is not enough, one must also avoid conflicts
with vapigen (see https://wiki.gnome.org/Projects/Vala/UpstreamGuide).

The missing directives prevent libxfce4util to be used from C++ code.
