This will help us to identify the patch corruption.
Meanwhile fix a wrong size parameter passed to bspatch.
(patch->data.size() into patch->data.size() - patch_offset).
Also remove the only usage of "ApplyBSDiffPatchMem()" and inline its
Sink function for simplicity.

Test: Prints SHA1 for corrupted patch in imgdiff_test.

Mostly for applypatch family APIs like ApplyBSDiffPatch() and
ApplyImagePatch(). Changing to size_t doesn't indicate they would
necessarily work with very large size_t (e.g. > ssize_t), just
similar to write(2). But otherwise accepting negative length doesn't
make much sense.
Also change the return type of SinkFn from ssize_t to size_t. Callers
tell a successful sink by comparing the number of written bytes against
the desired value. Negative return values like -1 are not needed. This
also makes it consistent with bsdiff::bspatch interface.

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.

Changing the field of 'Value' in edify to std::string from char*.
Meanwhile cleaning up the users of 'Value' and switching them to
cpp style.
Test: compontent tests passed.

If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same
library, there would be linking errors when generating a shared library
(or executable) that depends on the two libraries both.
Also clean up Android.mk files.
Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The
module will then default to "optional" which won't be built until needed.

update_engine need it for the new IMGDIFF operation.
Also removed __unused in ApplyImagePatch() as I got error building it
for the host, and I think it's dangerous not checking the size of the
input.
