Remote search providers install an auxiliary keyfile to specify
static information, such as the object path/bus name needed to activate
the binary. Such keyfiles also specify the application the providers
pushes results for; currently, we support two formats for application
information
- two fields, "Title" and "Icon" that specify a (translatable) title and
an icon name for display
- one field "DesktopId" that specifies the desktop file name of the
application backing the provider, which obsoletes the previous
Title/Icon syntax
Since all providers in GNOME use DesktopId now, and we need to ensure a
remote search providers is always backed by an application for future
development, this commit drops the support for the older syntax.
