ce58519e66 kernel: Reformat code using clang-format (#347) 
* The coding format is too messy, reformat to improve readability
  and get closer to Linux kernel coding style.

* While at it, update .clang-format file to linux-mainline state.

210f61949f kernel: apk_sign: fix return check for ksu_sha256 
upstream used IS_ERR to check for negative return and that is int,
so correct it.

This is one headache for old compilers.

ff6a68221f kernel: add wrapper for creds, refine disable_seccomp, revert some changes (#131) 
1. Wrapper for creds:
* Some older kernel does not have {.val}, so, for nicer compatibility support and clean code,
make some wrapper for credential use.
* After this change, do not use current_uid().val, instead, use ksu_current_uid(). For more
info, check kernel/include/ksu_creds.h.

2. Refine disable_seccomp (need to add k6.11+ support)

https://github.com/tiann/KernelSU/issues/2706

3. Revert "Handle unmount for isolated process correctly"
Reason: https://github.com/tiann/KernelSU/pull/2696#issuecomment-3181866301

4. consolidate most of the gaps

c0066b68f5 kernel: support the case that init_task.mnt_ns != zygote.mnt_ns(WSA) (#698) 
Basic support for the case that init_task.mnt_ns != zygote.mnt_ns(WSA),
just copy nsproxy and fs pointers for solve #276.

Note the copy in `apk_sign.c` is not required but suggested for
secure(ensure the checked mnt_ns is what ns android running, not created
by user, although many distributions does not have user ns.).

Tested with latest release on Win10 19045.3086(with WSAPatch).

Further review required for:
- [x] Security of this operation (without locking).
- [x] The impact of these modifications on other Android distributions.
