Subject: Always use the LocalePicker's preferred locale names.
X-Git-Tag: android-x86-6.0-r1~860^2~400^2^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=81395c8f3d908e2f41a147b33ca02fd1963af7ea;p=android-x86%2Fpackages-apps-Settings.git

Always use the LocalePicker's preferred locale names.

Without this change we have the odd situation where LocalePicker goes out of
its way to avoid saying certain things but then -- as long as there's more than
one locale for a given language -- Settings would happily report the name we'd
been avoiding. (Either because it's too specific or because it's too sensitive.)

Also remove the unused bit-rotted duplicate of the blacklist; even if we needed
to access that list directly, we should use LocalePicker's copy.
