/sbin must come before any other search path when TWRP is built for a
different version of Android than the one on which it will run.
Otherwise, as soon as any of the other paths becomes available via
direct action (i.e. the user mounts a file-system) or indirect action
(e.g. the user flashes a zip that mounts a file-system), incompatible
libraries will be prioritised and loaded instead of the correct ones
from /sbin in TWRP's ramdisk.
This will cause severe disruption of the TWRP environment. Toybox and
other dynamically linked binaries will immediately cease to work; and
since Toybox provides umount, it typically won't be possible to recover
from this state without a reboot.
For example, the following occurs when a Toybox applet is run on a
Samsung Galaxy S10 running Android 10, but using a version of TWRP built
for Android 9:
android:/ # getprop ro.boot.bootloader
CANNOT LINK EXECUTABLE "getprop": cannot locate symbol "_system_properties_init" referenced by "/system_root/system/lib64/libselinux.so"...
linker: CANNOT LINK EXECUTABLE "getprop": cannot locate symbol "_system_properties_init" referenced by "/system_root/system/lib64/libselinux.so"...

* without this A/B devices are writing 8MB+ uncompressed logs under persist/cache/recovery which increase in size over time. This can eventually leave persist partition OOM causing other cascading issues like crashing the modem during boot and bootloops.

This update will use pigz to compress the log that TWRP stores
on persistent storage in order to help with storing logs on the
persist partition.

Remove unused reference.
Change temp variables to size_t.
Update function calls for unused arguments.
Update static functions to ignore being defined
for each file that includes it.

Re-implemented SP800Derive in C++, which is added as the new key
derivation function in Android 9.0 May update. From file
services/core/java/com/android/server/locksettings/SP800Derive.java in
frameworks/base.
This is required to get TWRP working on any Android device that has a
screen lock set up after the May update.

* Set proper SELinux context for system-as-root system, AOSP uses "/"
in fstab while TWRP uses "/system_root" so an exception is necessary.
* Skip initializing context if the target partition doesn't exist in
/file_contexts e.g. /usb-otg.

Having the twrp_dd module definition right within the build rules
for the toolbox symlinks causes the toolbox tools (getprop, ...)
to be linked to dd instead of toolbox.
This happens because the symlinks are created using variables
from the "toolbox_recovery" module (e.g. LOCAL_MODULE_STEM).
Those are changed by the twrp_dd module definition.
Move the twrp_dd module definition to the end of the make file
(after the build rules for the symlinks) to fix this.
Fixes https://github.com/omnirom/android_bootable_recovery/issues/257

* Otherwise no context will be initialized but existing context will be
erased and lead to unexpected behavior, e.g., device no longer boots
after restoring a system backup due to missing valid seclabel of the
system partition.
