Ext4 filesystems like to be unmounted before rebooting. The Android system doesn't have a traditional Linux init setup, and shutting down the system was not much more than calling sync(2) and reboot(2). This adds a new function to libcutils called android_reboot(). By default, it calls sync() and then remounts all writable filesystems as read-only and marks them clean. There is a flag parameter in which the caller can ask for sync() not to be called, or to not remount the filesystems as read-only. Then it will call reboot(2) as directed by the other parameters. This change also updates adb, init and toolbox to call the new android_reboot() function. Fixes bugs 3350709 and 3495575. Change-Id: I16d71ffce3134310d7a260f61ec6f4dd204124a7
