Fix Ext4 filesystem support. This patch fixes the way the emulator handles Ext4 partition images. Before the patch: - The hardware property 'hw.useext4' was used to determine whether the partition images use yaffs2 (for 'no') or ext4 (for 'yes'). The default value was based on the API level, since ext4 is used since Android 4.4 (API level 19), but it was easy to get confused, resulting in the inability to properly boot the AVD. The symptom was not trivial, i.e.: - Mounting /system with the disk image failed, so the system kept using the ramdisk mount. - Later, logcat contained plenty of complaints that some stuff couldn't be found under /system/bin/ After the patch: - The partition format is simply auto-detected by probing the start of the disk image. The hardware property has not been removed because doing this breaks snapshots, but it is now tagged as deprecated. + Move the ext4 probing code from android/avd/util.* to android/filesystems/ext4_utils.* and add proper unit tests.
