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.

In zip mode, if a chunk is not deflate or its filename can't be found
in source chunks, the entire source file is used as old data for bsdiff,
To avoid repeatedly construct the suffix array used by bsdiff, we cache
the suffix array of the entire source file.

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.

We should always use unique_fd or unique_file to hold the FD or FILE*
pointer when opening via ota_(f)open functions.
This CL avoids accidentally closing raw FDs or FILE* pointers that are
managed by unique_fd/unique_file.
Test: recovery_component_test passes.
Change-Id: If58eb8b5c5da507563f85efd5d56276472a1c957
We were using the below sequence prior to the CL in [1].
unique_fd fd(ota_open(...));
ota_close(fd);
fd.reset(ota_open(...));
fd.reset() may unintentionally close the newly opened FD if it
has the same value as the early ota_open. The CL in [1] changed to
"ota_close(fd.release())" to avoid the issue. This CL adds a new
overloaded function ota_close(unique_fd&) to handle the release
automatically.
Similarly add ota_fclose(std::unique_ptr<FILE>&).

We use android::base::unique_fd() to avoid leaking FD. We also want to
call close (or ota_close) to explicitly check the close result. When
combining the two together, we need to release the unique_fd to avoid
closing the same FD twice.
