Adds support for partitions with checkpointing enabled. If the
checkpoint= fs_mgr flag is set, and the system has checkpointing on,
the partition will be mounted in checkpointing mode.
Test: Use vdc checkpoint commands, the checkpoint=fs fs_mgr flag
in the fstab, and a kernel containing the f2fs checkpoint
changes. https://lkml.org/lkml/2018/8/21/22

Debugging memory allocations on the nexus launcher unveiled significant memory allocations for the hashatable used in libziparchive, ~1MB.
This is partly because of the ZipString struct storing an entry in the table. The struct stored a pointer to a string (on 64 bit, 8 bytes) and the length to read from that pointer, 2 bytes. Because of alignment, the structure consumed 16 bytes, wasting 6 bytes.
Now, we store entries in the hashtable as a ZipStringOffset. This new structure stores a 4 byte offset from a fixed location in the memory mapped file instead of the entire address, consuming 8 bytes with alignment.
Bug: 79416399
Test: Builds successfully and manual testing by opening launcher on Pixel 2 shows precisely 50% decrease in memory allocated for the hashtable. From 909312 bytes to 454656.

We're moving apps and their libs to product_services for older
devices too, so mimic the rules in the default ld.config related
to product_services.
Also fix a one-off disparity between /product and /product_services
in ld.config.txt.

If there is no valid pre-compiled SEPolicy policy, init may call
secilc, which exists on the system partition. 1st stage init won't
always live on this partition, so we need to move this SELinux setup
to 2nd stage init, which always lives on the system partition, to
ensure that both secilc and its caller are updated together.

The system image is now a root image, even on devices that don't use
system-as-root. Fix remount to always remount /, to account for this.

Previously, if an intercept ends before we ask for a file descriptor

For A/B devices, the recovery image is typically provided as a ramdisk
paired with boot.img. Instead of repartitioning these devices to have
a separate recovery partition and have the new 1st stage ramdisk
paired with the boot.img, this allows setting
androidboot.force_normal_boot=1 on the kernel command line to have init
in recovery boot directly to a normal boot.
This requires /system_recovery_mount to be added in the DT fstab for
the system partition.

With replaced AOSP system.img, adb can be root by other test.
The fail is caused by the reason that logdw is still active after
__android_log_close().
This test has a potential bug.
proc/net/unix may contain '\0', then "grep" command will treat this file
as a bianry file.
Using "grep -a" instead of "grep" could be a safer way to get the right
results from bianry file.
