Factor out libimgdiff static library for testing purpose.
This CL adds the imgdiff tests on host and on target both (similar to
libimgpatch). In practice, we only need imgdiff binary on host, and
libimgpatch on target. But they should build and pass tests on both
platforms.
Test: recovery_host_test passes; recovery_component_test passes.

# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img
Running the tests
# After setting up environment and lunch.
mmma -j bootable/recovery
# Running the tests on device.
adb root
adb sync data
# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test
# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
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.
