Patching regular files is used in file-based OTA only, which has become
obsolete.

Test: Apply an incremental that patches the boot.img.
Test: /system/bin/install-recovery.sh works.

# To boot into the new recovery image

# Running the tests on device.

adb shell /data/nativetest64/recovery_component_test/recovery_component_test
Running the manual tests
recovery-refresh and recovery-persist executables exist only on systems without
/cache partition. And we need to follow special steps to run tests for them.
Execute the test on an A/B device first. The test should fail but it will log
some contents to pmsg.
Reboot the device immediately and run the test again. The test should save the
contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if
this file has expected contents.
ResourceTest validates whether the png files are qualified as background text
image under recovery.
1. `adb sync data` to make sure the test-dir has the images to test.
2. The test will automatically pickup and verify all `_text.png` files in
the test dir.
