Add basic process code for fsck.ubifs. There are following modes for fsck:
1. normal mode: Check the filesystem, ask user whether or not to fix
the problem as long as inconsistent data is found during fs checking.
2. safe mode: Check and safely repair the filesystem, if there are any
data dropping operations needed by fixing, fsck will fail.
3. danger mode: Answer 'yes' to all questions. There two sub modes:
a) Check and repair the filesystem according to TNC, data dropping
will be reported. If TNC/master/log is corrupted, fsck will fail.
b) Check and forcedly repair the filesystem according to TNC, turns
to rebuild filesystem if TNC/master/log is corrupted. Always make
fsck succeed.
4. check mode: Make no changes to the filesystem, only check the
filesystem.
5. rebuild mode: Scan entire UBI volume to find all nodes, and rebuild
filesystem, always make fsck success.

ubifs-utils: Adapt budget.c in libubifs2024-11-11T09:32:45+00:00Zhihao Chengchengzhihao1@huawei.com2024-11-11T08:37:07+00:00urn:sha1:e0e6a2998bc6d4402b1c392b710a47ee977db9c0
Adapt budget.c in libubifs, compared with linux kernel implementations:
1. Remove writeback related functions, there are no dirty pages/inodes
for UBIFS in userspace process.

ubifs-utils: Import UBIFS libs from linux kernel2024-11-11T09:32:45+00:00Zhihao Chengchengzhihao1@huawei.com2024-11-11T08:36:40+00:00urn:sha1:898499314c7073bbf6851db6542858921aeb6580
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.).
