Instead of adding search providers to the system as we find them, wait
until we loaded information from all the directories, and then add all
providers at once.
This will be useful when we will sort the providers information
according to the sort order saved in GSettings.

Initializing this synchronously means that we will possibly wait for the
process to be auto-activated and answering to our call.
If the process is already running it also might not answer immediately
our request, as it might be doing sync I/O.
The right thing to do is to initialize the proxy asynchronously; there
are try/catch blocks in place for when the object is not available, or
not properly initialized.

This is called in the main thread, which we should never block for
synchronous I/O.
Since the operation we're wrapping is async already, just use
g_file_query_info_async() instead.

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.

Currently we load all search providers from XDG_DATA_DIRS, so if
the same provider is installed several times in different directories,
we happily show duplicate results. To fix, keep track of all remote
providers we add and skip those that already have been loaded from a
different directory.

We strongly expect applications to use the same values for the
'Title'/'Icon' fields in their search provider .ini file as the
'Name'/'Icon' fields in their .desktop file. Rather than requiring
applications to duplicate those fields, allow them to specify a
'DesktopId' field instead to point to the corresponding .desktop
file, which makes it possible to ship search provider files without
translatable strings (which is nice given that merging translations
into search provider files lacks a standard rule).

Currently we pass an icon name for the 'icon' parameter of the
RemoteSearchProvider constructor. In hindsight, using a GIcon
instead will give us a bit more flexibility, so change it.

As shown in the previous commits, synchronous search is easily implemented
by the asynchronous search API. The only reason we still have a
synchronous search API is of historical reasons. Well, we're not a museum,
and git log can keep our fossils safe if need be....

Allow applications to register search providers by dropping a keyfile
into a well-known directory. For now, initialize all found providers;
long term, we probably want to give users the ability to restrict the
set of active search providers.

Add an asynchronous search provider for results from a DBus service
implementing the org.gnome.Shell.SearchProvider interface; this
will allow applications to hook into the Shell's search without
implementing it in Shell itself or requiring an extension.
