DB Wipe detection
- Create a check file for each database in order to detect
1) an unexpected DB file removal
2) DB wipe caused by a DB corruption.
- Either case, do a WTF to collect information on APR.
- Also print file timestamps in "dumpsys dbinfo". Example:
=====================
Database files in /data/system:
locksettings.db 20480b ctime=2018-10-23T22:48:35Z mtime=2018-10-23T22:48:35Z atime=2018-10-23T18:54:12Z
locksettings.db-wipecheck 0b ctime=2018-10-23T18:54:12Z mtime=2018-10-23T18:54:12Z atime=2018-10-23T18:54:12Z
notification_log.db 45056b ctime=2018-10-23T22:48:08Z mtime=2018-10-23T22:48:08Z atime=2018-10-23T18:54:13Z

Change-Id: I77fbeb0bb635c787aba797412f116475fecbe41c
Fixes: 117886381
Test: manual test
Test 1: corruption
1. Stop CP2 process (adb shell killall android.process.acore)
2. shell 'echo abc > /data/user/0/com.android.providers.contacts/databases/contacts2.db'
3. Launch the contacts app.
Test 2: Unexpected file removal
1. Stop CP2 process (adb shell killall android.process.acore)
2. shell 'rm -f /data/user/0/com.android.providers.contacts/databases/contacts2.db'
3. Launch the contacts app.
In both cases, logcat shows a client side stacktrace and also a WTF. (am_wtf)
