We have a general need for overriding more paths (e.g. "/tmp"), mostly
for testing purpose. Rename CacheLocation to Paths, and use that to
manage TEMPORARY_{INSTALL,LOG}_FILE.

We set the limit of the max stash size to 80% of cache size. But the
cache space can still be insufficient for the update if the log files
occupy a large chunk of /cache. So remove the old logs for now to make
room for the update.

Otherwise the applypatch executable will fail to back up the source
file to /cache when patching the recovery image.

Test: run applypatch from boot to recovery

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

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.

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.

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.

Also drop the "bootable/recovery" path in LOCAL_C_INCLUDES from
applypatch modules.
Test: lunch aosp_{angler,bullhead,fugu,dragon,sailfish}-userdebug;
mmma bootable/recovery

This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c 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).

This reverts commit 623fe7e701d5d0fb17082d1ced14498af1b44e5b.
Reason for revert: Need to address device-specific modules.
