We have added the support for building /product partition in build
system (the CL in [1]), where /product is an optional partition that
contains system files. This CL adds the matching support if /product
needs to be verified during A/B OTA (i.e. listed in care_map file).

Prior to this CL, the block verification works were assigned based on
the pattern of the ranges, which could lead to unbalanced workloads. This
CL adds RangeSet::Split() and moves update_verifier over.
a) For the following care_map.txt on walleye:
system
20,0,347,348,540,556,32770,33084,98306,98620,163842,164156,229378,229692,294914,295228,524289,524291,524292,524348,529059
vendor
8,0,120,135,32770,32831,94564,98304,98306
Measured the time costs prior to and with this CL with the following
script.
$ cat test_update_verifier.sh
#!/bin/sh
adb shell stop
adb shell "cp /data/local/tmp/care_map.txt /data/ota_package/"
for i in $(seq 1 50)
do
echo "Iteration: $i"
adb shell "bootctl set-active-boot-slot 0"
adb shell "echo 3 > /proc/sys/vm/drop_caches"
adb shell "time /data/local/tmp/update_verifier"
sleep 3
done
Without this CL, the average time cost is 5.66s, while with the CL it's
reduced to 3.2s.
b) For the following care_map.txt, measured the performance on marlin:
system
18,0,271,286,457,8350,32770,33022,98306,98558,163842,164094,196609,204800,229378,229630,294914,295166,501547
vendor
10,0,42,44,85,2408,32770,32806,32807,36902,74242
It takes 12.9s and 5.6s without and with the CL respectively.
Fixes: 68553827
Test: recovery_unit_test
Test: Flash new build and trigger update_verifier. Check the balanced
block verification.

'group_range_count' doesn't properly consider the pair-wise range
structure. It may split the ranges into wrong pairs if it evaluates to
an odd number.
For example, for an input range string of "6,0,2,10,12,20,22" with 4
threads, group_range_count becomes 1. It would then try to verify (0,2),
(2,10), (10,12) and (12,20). Note that (2,10) and (12,20) are not valid
ranges to be verified, and with (20,22) uncovered.
Bug: 68343761
Test: Trigger update_verifier verification. Check the number of verified
blocks against the one in care_map.txt.

This CL is to change update_verifier to verify blocks in parallel to
maximize storage bandwidth, it also preallocate the buffer to avoid
vector allocation within reading loop.
Test:

Bootloaders using libavb will set androidboot.veritymode=disabled if
the "disable dm-verity" flag has been set. Additionally if the
"disable verification" flag is set androidboot.veritymode will not be
set at all. Handle both cases.
Without this fix we'll end up in a bootloop.
Test: Manually tested on a device using AVB.

update_verifier should be backward compatible to not reject legacy
care_map.txt from old releases, which could otherwise fail to boot into
the new release.
For example, we've changed the care_map format between N and O. An O
update_verifier would fail to work with an N care_map.txt - a) we have
switched update_verifier to read from device mapper in O; b) the last
few blocks that contain metadata can't be read via device mapper. This
could be a result of sideloading an O OTA while the device having a
pending N update.
Bug: 63544345
Test: As follows on sailfish:
1. Flash the device with this CL;
2. Put a copy of N care_map.txt at /data/ota_package/. Restore the
permissions properly ('cache' group);
3. `adb reboot bootloader`;
4. `fastboot set_active <current_slot>`
5. Device boots up into home screen, with a warning in logcat that says
it has skipped legacy care_map.txt.

When using AVB, PRODUCT_SUPPORTS_VERITY is not set so check for
BOARD_ENABLE_AVB as well. Also AVB sets up the root filesystem as
'vroot' so map that to 'system' since this is what is
expected. Managed to test at least that the code is at least compiled
in:
$ fastboot --set-active=_a
Setting current slot to 'a'...

Update_verifier will reboot the device if it fails to read some blocks
on the care_map when veritymode=eio. Also make some partition name
changes to match the care_map.txt.
Test: Update_verifier reboots the device after read failures in eio mode.

For devices that are not using dm-verity, update_verifier can't verify
anything, but to mark the successfully booted flag unconditionally.
Test: Successfully-booted flag is set on devices w/o dm-verity.
Test: Successfully-booted flag is set after verification on devices w/
dm-verity.

update_verifier used to read from system_block_device, which bypasses
dm-verity check completely. Switch update_verifier to read the corresponding
'/dev/block/dm-X' instead. U_v gets the verity block device number by
comparing the contents in '/sys/block/dm-X/dm/name'.
Bug: 34391662
Test: update_verifier detects the corrupped blocks and dm-verity trigger the reboot on Sailfish.

marking the active slot as successfully booted).

The getService() and registerAsService() methods of interface objects
now have default parameters of "default" for the service name. HALs
will not have to use any service name unless they want to register
more than one service.
Test: builds; verify HAL still works

update_verifier checks the integrity of the updated system and vendor
partitions on the first boot post an A/B OTA update. It marks the
current slot as having booted successfully if it passes the verification.
This CL doesn't perform any actual verification work which will be
addressed in follow-up CLs.
