ebb0ec6c42 Make xmmap() returns nullptr when fails 
In the constructor of mmap_data, there are two possible values when fails: nullptr if fstat() fails, and MAP_FAILED if mmap() fails, but mmap_data treated MAP_FAILED as valid address and crashes.

Invalidate Samsung's persist.sys.zygote.early 
Samsung FDE devices with the "persist.sys.zygote.early=true" property will cause Zygote to start before post-fs-data. According to Magisk's document, the post-fs-data phase should always happen before Zygote is started. Features assuming this behavior (like Zygisk and modules that need to control zygote) will not work. To avoid breaking existing modules, we simply invalidate this property to prevent this non-standard behavior from happening

Fix #5299, fix #5328, fix #5308

c38b826abf Skip overlayfs for post-fs-data mount 
adb remount will introduce overlayfs for /system and /vendor, we should
skip mounting as overlayfs. This also helps us support overlayfs Magisk
later.

19182ffddf If dt fstab contains error, fallback to default fstab 
See https://cs.android.com/android/platform/superproject/+/master:system/core/init/first_stage_mount.cpp;drc=master;l=155

From the source of `FirstStageMount`, dt fstab can fail gracefully and
if any error occurs it will fall back to default fstab. Magisk now
replaces the default fstab and dt fstab unconditionally, bringing potential
errors to the default fstab and causing init fails to load partitions.

Further fix oplus.fstab support 
* Further fix `oplus.fstab` support

In some oneplus devices, `oplus.fstab` does exists but `init` never
loaded it and those entries in `oplus.fstab` are written directly to
`fstab.qcom`. Previous implementation will introduce duplicate entries
to `fstab.qcom` and brick the device. This commit filters those entries
from `oplus.fstab` that are already in `fstab.qcom` and further filters
duplicated entries in `oplus.fstab` (keep only the last entry).

Fix #5016

* Fix UB

Since we moved entry, we need to explicitly copy its member.
For c++23 we can use `auto{}`.
