2024-11-11ubifs-utils: Adapt orphan.c in libubifsZhihao Cheng
Adapt orphan.c in libubifs, compared with linux kernel implementations: 1. Keep the commit related implementations, because do_commit depends on these functions which will be invoked in fsck. 2. Keep the orphan replaying implementations, because fsck needs them. 3. Other implementations are removed which won't be used in mkfs/fsck.

2024-11-11ubifs-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.).
