For both of these, because of optimizations a few patches ago, we
ended up relying on hash table ordering which caused instability
in the application well among other things. Define an ordering
for both.
The favorites is just the order of the GConf keys, and new items
get appended. In the future we should allow insertion at any
point which the grid could use.
For running applications order, define a new "initially_seen_sequence"
transient variable which is just an monotonically incrementing
integer assigned to an application for the first time we saw it
running in this session. When an application is closed, it's reset.
The previous application monitoring code was originally designed
to be based on WM_CLASS, which was then resolved on a server.
We have that resolution code locally now, so instead
of saving WM_CLASS data, save application IDs.
Also, inside the WM we have a much better
infrastructure for tracking windows. In particular, rather
than polling, we can just watch for focus notification on
the display, and window add/remove.
Instead of polling XScreensaver, use DBus to watch org.gnome.Session
which already has an idle time watch.
Now there is no polling at all inside the monitor.
Before, we looked up application data in several ways; the ShellAppSystem
exported just application ids (though it parsed the .desktop files internally),
and we'd create a Gio.DesktopAppInfo object (reparsing the desktop file again),
wrapping that inside a JavaScript AppInfo class, and finally the AppDisplay
would again parse the .desktop file to get the categories.
Also, to look up applications by id previously, we traversed the entire
menu structure each time.
Some qualities such as the NoDisplay flag were not easily exposed in the old
system. And if we wanted to expose them we'd have to change several different
application information wrapper classes.
All in all, it was quite suboptimal.
The theme of this new code is basically "just use libgnome-menus". We do
not call into Gio for app lookups anymore. The new Shell.AppInfo class
is a disguised pointer for the GMenuTreeEntry item.
To fix the caching, we keep a simple hash table of desktop id -> ShellAppInfo.
Add a GConf key for favorites, and API for retrieving them.
Also add shell_app_system_lookup_basename, which we use from
the app monitor to look up WM_CLASS ids.
Track all windows; at the time of opening (and shell startup)
we call into ShellAppSystem to take the WM_CLASS property and
try to find an associated .desktop file.
Add mozilla-firefox to the list of our WM_CLASS workarounds.
Add shell_global_get_screen, since it's often used.
The code here is significantly cleaner if we use the data Metacity
already has cached and validated, rather than talking to X directly.
Also some preparatory work for extending the monitor API by
clarifying the name of the (current) main entry point.
We need to reset the popularity GSList* at start, and everytime we load data about a another activity. This also implies fixing the typo about (activity != -1).

This solves several issues:
- use built-in default so that app monitoring is enabled when schemas are not installed
- don't start/stop timers without checking their previous state
- unreference the default GConfClient
- use #define for the GConf key path
ShellAppMonitor now depends on gmenu to load menus.
Use the menu data from ShellAppMonitor to show a menu list.
GenericDisplay implementations can now have a sidebar area. We
handle keystrokes such as left/right explicitly.
Some internal API changes to account for the fact that a display
can have another filter in addition to the search.
