This reverts commit 589c8d1e44.
Reason for revert: fuzzer crashes immediately on line 99 as vector is empty
Change-Id: I5e56a94671a43cd131c250d98f7cfae3c96f34ab
The FuzzerDefs.h APIs are internal to the fuzzer and aren't available
when the fuzzer is built with a custom private libc++, so remove the
ExtraCountersBegin/ExtraCountersEnd assertions and inline the array
clearing.

Right now we encode the per mountpoint scratch dir name like this:
/system -> /mnt/overlay/@system/
/product/app -> /mnt/overlay/@product@app/
This CL changes it to:
/system -> /mnt/overlay/system/
/product/app -> /mnt/overlay/product@app/
This makes it so that the encoded path for top-level mountpoints (like
/system, /vendor) would have the same encoded scratch dir as before
https://r.android.com/2795755 was introduced.
With this change old first-stage-init can handle top-level remounts
correctly. However for mountpoints with '/' in them, their remount
scratch dirs would be encoded with the new format, and old
first-stage-init would ignore and not setup these during boot.
This makes the remount mechanism to function partially when running on
an old ramdisk (first-stage-init) + new system combo.
Normally we expect the init_boot ramdisk to be upgraded alongside
system.img, so this change isn't strictly needed. However there are
cases where we might want to develop new OS features on old vendor
platform, thus this change.

Right now we assume all RW mounts (minus /data & special FS) are
remounted by us and we apply the remount/overlayfs related checks
on them unconditionally. This would generate false positives when
a partition was RW but not remounted by us.
The test should instead check mounts that were remounted by us
(transitioned from RO to RW after adb-remount), and ignore
partitions that were already RW before running adb-remount.

Assign CPUSET_SP_BACKGROUND taskprofile to snapshot merge threads.
This will ensure that the threads will not run on big cores.
Additionally, reduce the flushing of data to 1MB after merging REPLACE ops.
No major regression observed on snashot merge time.
On Pixel 6 for incremental OTA of 500M, snapshot merge time increased
from 72 seconds to 76 seconds after this patch.

Before this patch, DeleteDeviceWithTimeout was checking that the dev
node (i.e. /dev/block/dm-XX) is deleted after the call to DeleteDevice
API. Since ueventd first deletes the symlinks that correspond to a
device and only then deletes this device node, this assertion introduced
a race condition (DeleteDevice API waits for the symlink to be deleted).
This patch changes the DeleteDeviceWithTimeout test to check that unique
path of the device has been deleted.

According to aosp/1908136, the current flow is
1. factory reset formatted raw disk.
2. next boot tries to convert it to metadata encryption
2.a mount sda27
2.b umount sda27
2.c encrypt_inplace()
2.d fsck on dm-x
2.e mount dm-x
If there are some write file operations between 2.a and 2.b, encryption
might fail. To mitigate, change the mount in 2.a to readonly if we know
we are going to do encrypt_inplace.

Performance of COW v3 is now on par with v2 in both multi-threaded and
single threaded configurations. Note, v2 cow writer can cache up to 1024
blocks in memory if multi-threaded compression is enabled(even though
batch size is configured as 200). For a fair comparison, benchmarks are
ran with batch size of 256. For batch size of 256 or greater, v2 and v3
have similar multi-threaded performance.
