Squashed commit of the theme engine support.

Updated 4.2 support for the old T-Mobile theme engine, as usual
needs the provider and switcher apps installed as well.

I'm finally dropping the 400+ commit history on this, since everybody
else keeps picking it up from CM as a single patch anyway... But
for the record, nothing of this would be possible without Josh, Ed,
and the rest of the TMo guys who wrote and maintained it until 2.2:

Fix theme provider crashing for non-primary user.

PackageManagerService's context is for user 0, so if the theme provider
for other users was invoking the getInstalledThemePackages() method, the
themes provider crashed as it doesn't have the INTERACT_ACROSS_USERS
permission.
Fix that (and simplify code) by making getInstalledThemePackages()
return the installed themes for the current user, which was probably the
intent anyway.

PackageManager: Prevent themes from going into ASEC containers

Themes on ASEC cause all kinds of random timing/racey issues at boot
time, and more kinds of racey concurrency issues at uninstall/upgrade
time. Stop them from getting into containers at all.

ThemeUtils: Retain the original package name in themed UI context

In order for themes to reflect on system elements, we're changing
their context, including the package name.

This breaks anything that tries to identify system elements,
most notably any users of the uiautomator. Trying to do
'UiSelector().packageName("android")' to find, for example,
a force-close dialog will fail.

Fixes com.android.cts.uiautomatortest.CtsUiAutomatorTest#testUiWatcher
