This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This makes the applypatch executable a vendor module.
This change supports making dependencies of the applypatch executable available
to applypatch, which is now on vendor.
Since install-recovery.sh is now a vendor service, we add the
applypatch/vendor_flash_recovery.rc file to /vendor/etc/init to start the
service.
Bug: 68319577
Test: Ensure that recovery partition is updated correctly.

A number of utility functions are intended for serving recovery's own
use. Exposing them via libotautil (which is a static lib) would pass the
dependencies onto libotautil's users (e.g. recovery image, updater, host
simulator, device-specific recovery UI/updater extensions etc). This CL
finds a new home for the utils that are private to recovery.
Test: mmma bootable/recovery

Implement the simulator runtime and build the updater simulator as a host
executable. The code to parse the target-files and mocks the block devices
will be submitted in the follow-up.

Therefore, libinstall becomes the sole owner to handle the request
from minadbd service.
The change also includes
1. move logging.cpp out of librecovery
2. drop the dependency on common.h
3. now it's more sensible to move the wipe_cache as part of
install_package. move the wipe_cache to the end of the function.
Bug: 130166585
Test: wipe data and cache from menu

otautil/roots.h includes <fstab/fstab.h>, but users of otautil/roots.h
don't need to explicitly depend on libfstab unless they have a real
need.
Also remove the unneeded include of <fstab/fstab.h> from
fsck_unshare_blocks.cpp.

Build libinstall as a shared library. Also drop the dependency on the
global variables in common.h.

The recovery-persist used to look for the related recovery logs in
persist storage, and copy them under /data/misc/recovery during the
normal boot process.
As we also want to find out the sideload information from last_install,
it makes more sense to move the parse & report of non-a/b metrics to
recovery-persist. Thus we can avoid the race condition of the file
system between the native code and RecoverySystem.
Bug: 114278989
Test: unit test pass, check the event buffer for metrics report

Test: `m -j installclean && mmma -j bootable/recovery` with
aosp_taimen-userdebug
Test: Build (`m -j bootimage`) and boot into recovery. Check that
`adb sideload` and `Run graphics test` both work.
Test: Run recovery_unit_test and recovery_component_test on marlin.

This breaks the dependency on common.h (which belongs to
recovery/librecovery) from librecovery_ui. reboot() is now owned by
libotautil, which is expected to be a leaf node to be depended on.
With the change, recovery and updater also share the same reboot() code
now.

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.

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

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.

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).
