7 daysubifs-utils: Adapt debug subsystem in libubifsZhihao Cheng
Adapt debug subsystem(debug.c, debug.h) in libubifs, compared with linux kernel implementations: 1. Only keep the disk data and space statistics dumping implementations, dbg_walk_index and add_size which are used by fsck, other debuging related implementations and sysfs interfaces are removed, because fsck will check fs in another way. 2. Change the behavior of ubifs_assert_failed(), make filesystem readonly when assertion is failed.

7 daysubifs-utils: Import UBIFS libs from linux kernelZhihao Cheng
Import UBIFS libs from linux kernel. Next patches will replace ubifs related source code with implementation of linux kernel, which makes userspace implementation be same with linux kernel, then fsck.ubifs can resuse the code. Notice: lpt.c is modified with [1] applied. ubifs.h and orphan.c are modified with [2] applied, journal.c is modified with [3] reverted( because fsck runs in a single thread, so waitqueue is not needed to be implemented in userspace.).
