Remove dependencies on zip_archive specific data structures. In follow
up changes, this method will be promoted to a public API and used from
androidfw/ZipUtils as well as tools/zipalign, thereby allowing us to
remove a near-exact copy of this code and to simplify depdencies.

As a VNDK module, Android.bp must have 'vndk' tag as well as
'vendor_available: true'.
The 'vndk' tag for VNDK module is formated as below:
vndk: {
enabled: true,
},
VNDK modules will be installed both in system/lib(64) as normal and
in system/lib(64)/vndk as a vendor variant.

The use of ReadAtOffset is meant to allow concurrent access
to the zip archive once it has been loaded. There were places
where this was the case, and some places that did a seek + read
combination, which could lead to data races.
NOTE: On Windows, we are not using pread as the implementation of
ReadAtOffset, therefore the guarantees on Windows are weaker.
On Linux, pread allows the file descriptor to be read at a specific
offset without changing the read pointer. This allows inherited fd's
and duped fds to be read concurrently.
On Windows, we use the ReadFile API, which allows for an atomic seek +
read operation, but modifies the read pointer. This means that any mix
use of ReadAtOffset and Read will have races. Just using ReadAtOffset is
safe.
For the Windows case, this is fine as the libziparchive code now only
uses ReadAtOffset.

libziparchive headers are moved from the global include directory
(/system/core/include) to the local directory inside libziparchive.
Note: /system/core/include/ziparchive still exists as a symlink to
libarchive/include/ziparchive. This will be removed when there is no
header-only dependency to libziparchive.

- Ensure that the compressed and uncompressed lengths in the data
descriptor match those in the central directory.
- Calculate CRCs for compressed entries and ensure that those CRCs
match the information in the central directory / data descriptor.
This is currently guarded by a flag and will be turned on at a
later stage.
- Finally, always trust the LFH when it comes to indicating the
existence of a data descriptor. We no longer require this info to
match the central directory to bring this in line with other zip
processing tools. (see NOTE in the included change).

This patch adds two benchmarks that measure the performance of some
operations of libziparchive.
Both benchmarks are creating a temporary zip file containing file
names of uniformly distributed lengths. The creation of the zip
file is not timed in the benchmarks.
- FindEntry_no_match tries to find an inexisting entry in the files
of the zip archive, in order to force the code to examine all the
files in the archive.
- Iterate_all_files uses the iterate function to list all the files
in the archive.

Based on the compressed size of a file entry,
the decision needs to be made to instead store the file
uncompressed. This adds support to ZipWriter to backup
its last file entry.
The file is now always truncated when the EOCD is written out,
to account for the case where a file entry is backed-up and the
resulting file written is much smaller, leaving garbage data at
the end of the file.
This change also includes a rename of FileInfo -> FileEntry.
This struct was private (now public), so it shouldn't affect any
clients.

FileWriter::Create() calls ftruncate(2) to truncate the destination
file, which doesn't work with FD that references a block device. It
leads to kIoError when calling ExtractEntryToFile() to extract an entry
to block device FD.
As a result, it fails the package_extract_file() command in OTA updates
(e.g. 'package_extract_file("boot.img",
"/dev/block/platform/soc.0/f9824900.sdhci/by-name/boot")').
This CL skips the call to ftruncate(2) if FD references a block device.

system/core/include is included in the global include path using
-isystem, which hides all warnings. zlib.h is included through
system/core/include/ziparchive/zip_archive.h, which was hiding warnings
in it. Use a #pragma around the call to deflateInit2, it is a macro
that expands to an old-style cast, in preparation for moving from
-isystem to -I. Also move the ZipString constructor to zip_archive.cc
so it can assert on the length of the string parameter and fix an
implicit conversion from size_t to uint16_t.

ag/880725 modified ReadAtOffset to seek then read from the open
file descriptor. Previously pread64 was used to provide atomic
behaviour.
This causes races when multiple threads are trying to access data from
the file. This is supported, so this change reverts the relevant parts
of the above CL to restore the old behaviour.
