This prepares for upcoming changes that refactor verity-related
functions into classes.
This CL makes minimal changes to the moved functions, by creating a new
BuildVerityImageError class in verity_utils.py replacing the former
BuildImageError that's specific to build_image.py. As part of the
change, it also moves the tests for AVBCalcMinPartitionSize into
test_verity_utils.py.
Test: python -m unittest test_verity_utils
Test: `m dist` with aosp_marlin-userdebug (Verified Boot 1.0)
Test: `m dist` with aosp_taimen-userdebug (Verified Boot 2.0)
Change-Id: I19b52714d8980705ea1f9484ac03eb0af9483240
All the releasetools unittests extend the common base class of
test_utils.ReleaseToolsTestCase. Define tearDown() in the base class to
do the clean-up works.
Test: `pylint --rcfile=pylintrc test_*.py`
Test: `python -m unittest discover .`

There's a naming convention between the testcase and the class/method
being tested.
Also remove VerifiedBootVersion2HashtreeInfoGenerator as it's merely a
placeholder without telling anything much (e.g. whether it's to be
implemented or working as intended).
Test: python -m unittest test_verity_utils
Change-Id: Ieb156765c865aa551e3882f381e3a6db2cac4cbc
Generate the transfer command "compute_hash_tree" for incremental
updates of the non-A/B devices that enable verified boot 1.0
Other changes include:
i. factor out verity_utils to use both in build_image and blockimgdiff
ii. add a new flag 'hashtree_info_generator' in sparse_image to generate
the hashtree information.
Bug: 25170618
Test: generate a package for aosp_angler; and run simulator
