26f00cda4b introduced a bug where an
APK entry's extra field is padded for alignment purposes when no
padding is necessary because the entry is aligned without any padding
bytes.

This patch uses subprocess.communicate instead of subprocess.wait to
prevent deadlock if any of the child processes outputs too much data,
and redirects the subprocess output to stdout when running in verbose
mode.
With this patch `ota_from_target_files -v` prints the delta_generator
output in stdout, and no output if '-v' is not passed.
Bug: None

This adds the ApkVerifier class which verifies APKs using APK
Signature Scheme v2 only. In a follow-up commit this class will be
extended to verify APKs using JAR signature scheme when necessary.
The APK verifier is designed to not just verify an APK, but also
report errors, warnings, and information about signers in a structured
way, to enable tools to surface this information to users in various
ways.

This modifies JAR signing code to produce DSA signatures which are
accepted by all Android platforms rather than only API Level 9 and
higher.
The issue is that by default Bouncy Castle uses OID 1.2.840.10040.4.3
(dsaWithSha1) in PKCS #7 CMS SignerInfo whereas Android accepts that
only since API Level 9. However, OID 1.2.840.10040.4.1 (dsa) is
accepted by all Android platforms.

In preparation for including them in prebuilts/build-tools.
acp: We use a prebuilt in prebuilts/sdk, but it's not part of the sdk.
ijar: We use the host libstdc++ to workaround the lack of libc++ on
some unbundled branches.
ziptime: We disable this on unbundled builds, due to the lack of libc++.

Improve efficiency of using the DataSource abstraction.

This adds getByteBuffer and copyTo methods to the DataSource
abstraction. These methods enable the client to avoid unnecessary
copying of the data source's data.

findleaves.py needs to be able to search multiple directories for
multiple filenames (Android.bp and Android.mk). Add support for a new
--dir= option to specify one or more directories to search, and then
treat any remaining options as filenames. If no directories are
specified, fall back to treating only the last option as a filename and
the rest as directories.

This switches signapk's APK signing from its own signing logic to that
offered by apksigner-core library. OTA update package signing logic
remains inside signapk codebase.

1. This adds way to obtain a DataSource which represents a region of
data contained in the DataSource.
2. This fixes a design bug in "feed" method where the size parameter
was an int instead of long.
3. This fixes a bug in ByteBufferDataSource where its mSize field was
a long instead of an int (ByteBuffer's length cannot be more than
2^31).

Data of uncompressed APK entries is often aligned to a multiple of 4
or 4096 in the APK to make it easier to mmap the data. Unfortunately,
the current method for achieving alignment suffers from two issues:
(1) the way it uses the Local File Header extra field is not compliant
with ZIP format (for example, this prevents older versions of Python's
zipfile from reading APKs: https://bugs.python.org/issue14315), and
(2) it does not store information about the alignment multiple in the
APK, making it harder/impossible to preserve the intended alignment
when rearranging entries in the APK.
This change solves these issues by switching to a different method for
aligning data of uncompressed APK entries. Same as before, alignment
is achieved using Local File Header entry field. What's different is
that alignment is achieved by placing a well-formed extensible data
field/block into the extra field. The new field/block contains the
alignment multiple (e.g., 4 or 4096) as well as the necessary padding
(if any). Compared to the original alignment method, the new method
uses 6 more bytes for each uncompressed entry.
