2024-11-11ubifs-utils: Adapt key.h in libubifsZhihao Cheng
Adapt key.h in libubifs, compared with linux kernel implementations: 1. Add '__unused' modifier for unused parameters to avoid compiling warnings. 2. Remove some functions(eg. lowest_dent_key, dent_key_init_flash) which won't be used in fsck/mkfs.

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.).
