It used to keep track of the stat(2) info (e.g. st_mode/st_gid/st_uid)
while patching a file in file-based OTA.
Test: Build and use the new updater to apply an update on bullhead.

An interrupted update may stash extra blocks in /cache, leading to a
failure when checking the cache size. We can save the incremented
retry_count in the BCB before installing the update; and distinguish
a fresh update from an interrupted one this way.
Bug: 68679601
Test: An interrupted update reapplies successfully.

fs_mgr passes negative length as offset for crypt_footer. We need
to compute the actual device size for this case in addition to
when length is zero.

Also add a verbose option. And we won't print messages of 'info'
severity unless '-v' is present.
Test: run imgdiff and check the logs.

'-Wimplicit-function-declaration' is not needed (it's for C89) and
already enabled by -Wall.
For '-Wno-missing-field-initializers', don't see any existing case that
requires the flag.
Test: `mmma -j bootable/recovery` on aosp_{bullhead,marlin}-userdebug.

It used to be "const Value*", but nullptr won't be a valid input.
Test: recovery_host_test; recovery_component_test

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.
