Tianjie Xu b4e3a370bf Set the update locations to default in CacheLocation's constructor
Otherwise the applypatch executable will fail to back up the source
file to /cache when patching the recovery image.

Bug: 74198354
Test: run applypatch from boot to recovery

Tianjie Xu 3bbb20f557 Add a singleton CacheLocation to replace the hard coded locations
This class allows us to set the following locations dynamically:
cache_temp_source, last_command_file, stash_directory_base.

In the updater's main function, we reset the values of these variables
to their default locations in /cache; while we can set them to temp
files in unit tests or host simulation.

Test: unit tests pass

Tao Bao 160514bf2b Load-balancing update_verifier worker threads.
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.

Tao Bao 6798315327 otautil: Remove the aborts in RangeSet::Parse().
We used to CHECK and abort on parsing errors. While it works fine for
the updater use case (because recovery starts updater in a forked
process and collects the process exit code), it's difficult for other
clients to use RangeSet as a library (e.g. update_verifier).

This CL switches the aborts to returning empty RangeSet instead. Callers
need to check the parsing results explicitly.

The CL also separates RangeSet::PushBack() into a function, and moves
SortedRangeSet::Clear() into RangeSet.

Test: recovery_unit_test
Test: Sideload an OTA package with the new updater on angler.
Test: Sideload an OTA package with injected range string errors. The
      updater aborts from the explicit checks.

Tao Bao 4568582002 otautil: Move RangeSet implementation into rangeset.cpp.
Since it has grown much larger, users of the header shouldn't compile
and carry their full copies.

Also add missing header includes in imgdiff.cpp and imgdiff_test.cpp.

Test: recovery_unit_test; recovery_component_test; recovery_host_test

Tao Bao 09e468f84c Move rangeset.h and print_sha1.h into otautil.
Also drop the "bootable/recovery" path in LOCAL_C_INCLUDES from
applypatch modules.

      mmma bootable/recovery

Tao Bao 1fc5bf353a Revert "Revert "Move error_code.h into otautil.""
This reverts commit 26436d6d60 to re-land
"Move error_code.h into otautil.".

This way it stops requiring relative path ".." in LOCAL_C_INCLUDES
(uncrypt and edify). Soong doesn't accept non-local ".." in
"local_include_dirs".

This CL needs to land with device-specific module changes (e.g. adding
the dependency on libotautil).
