44f005077d Don't copy sepolicy.rule to /persist on boot
* This seems to be a logic that has been abandoned for a
   long time. Now we automatically choose which partition
   to store sepolicy.rule. Furthermore, touching /persist is
   what we should avoid doing whenever possible.

95c964673d Initialized _root properly
Fix #4204

`_root` is uninitialized for non-root nodes. And it will cause `module_node::mount` fail because it uses `root()`. Once the bug is triggered, signal 11 is received but Magisk catch all signals and therefore stuck forever.

e136fb3a4f Remove outdated sepolicies
* Support deodexed ROM: This should not be done and dexpreopt is mandatory since P
   Xposed: Xposed handles them just fine, at least in the latest version 89.3
   suMiscL6: For whatever audio mods, a leftover of phh time
   Liveboot and suBackL6: Was for CF.lumen and LiveBoot, not needed now

 * Also cleanup binder sepolicies since we allow all binder transactions.

Fix random return value of faccessat() in x86
faccessat() should return 0 when success, but it returns random number with errno == 0 in x86 platform.

It’s a side effect of commit bf80b08b5febd3f311108ff1c6e6a6bf2d1113b7 when magisk binaries ‘corretly’ linked with library of API16 .. lol

da723b207a Allow 3rd party code to load pre-specializing
Magisk's policy is to never allow 3rd party code to be loaded in the
zygote daemon process so we have 100% control over injection and hiding.
However, this makes it impossible for 3rd party modules to run anything
before process specialization, which includes the ability to modify the
arguments being sent to these original nativeForkAndXXX methods.

The trick here is to fork before calling the original nativeForkAndXXX
methods, and hook `fork` in libandroid_runtime.so to skip the next
invocation; basically, we're moving the responsibility of process
forking to our own hands.

947a7d6a2f Support rootwait cmdline parameter on legacy SAR
On devices where the primary storage is slow to probe it makes sense to
wait forever for the system partition to mount, this emulates the
kernel's behaviour when waiting for rootfs on SAR if the rootwait
parameter is supplied.

This issue was encountered with some SD cards on the Nintendo Switch.
