Add Search to the Settings App (initial release)
- add basic UI for search
- build the search Index thru sqlite FTS4 (faster than FTS3)
- create the search Index on the fly depending on the locale
- re-index if there is a configuration change
- re-index too if the Android build version has changed (usefull
for an Android OTA or when a new Android version is pushed as
we need to recompute the Index)
- search thru "title" and "summary" Preference's data
- group results in the same order of the Settings categories
into the Drawer
- rewrite "title" and/or "summary" if they are containing
an hyphen "\u2011"
- add Preference Keywords (only for the Settings App) in the
Index and allow search on them (Wi-Fi network preference is
used as an example)
Known restrictions:
- we cannot yet search for "dynamic settings"
- ... nor we cannot search for settings coming from an external App
(like the Phone App and its related settings that are surfacing
into the Settings App).
- will need a few other CLs to add more keywords (and have them translated)
