Notify callbacks on "any" wallpaper change

Callbacks are not notified when the wallpaper is changed to
a live wallpaper.  This patch notifies callbacks of the change
regardless of the type of wallpaper be set.

CM11 Themes: Clear wallpaper mixnmatch entry on external change

If a wallpaper is applied from a theme and the wallpaper is changed
from an external source, the theme is still shown to have its
wallpaper applied.  This patch will clear this value out when a
wallpaper change is detected that is not from the ThemeService.

SignalStrength: Hotfix TD-SCDMA take 2

The previous approach worked for 3G, but failed with TD-LTE. Let's
try something different to make them both work, and use the derpy
LTE checks only if a GSM signal is present.

Themes: Fix bad idmaps for system themes

For a system installed theme or a user who cleared his resource-cache,
there were empty idmaps for some packages.

[Details]
During startup PM could reach the theme package first before the target app was scanned in yet. This
would cause aapt to be skipped. Then when the target app is being installed in startup,
PM would try to create idmap pairs but it would fail since the resources from the theme
were not compiled for that target app.

Also cleaned up PM idmap/aapt creation a little bit more

Avoid calling idmap w/ trailing whitespace [1/2]

installd performs a buffer over-read if trailing ws is sent to it.
No observable effect found yet for idmap, but until installd is
fixed upstream, best to play it safe.
