Before this patch, btrfs-convert never copy ext* inode flags to corresponding btrfs inode flags. This makes common flags like APPEND/SYNC/SYNCDIR/IMMUTABLE not copied to btrfs inode. This patch introduces ext2_convert_inode_flags() function to handle the convert, so btrfs-convert can copy as many inode flags as possible.
