libutils, libz and libbase are being used as shared lib by many other
modules.
So using their shared lib will reduce total image size.
Size diffs on angler build image are as follows.
libziparchive.so : 103844 -> 41680 (-62164)
libnativeloader.so: 50824 -> 25104 (-25720)
total : (-87884)
Test: building succeeded, and the image was tested on angler.

On 32 bit system those calls may fail if one tries to unpack files which
are bigger than 2GB.
Use large file system support to fix this problem.
Test: unpack a file bigger than 2GB on 32 bit Android systems

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.

Test: ziparchive-tests works.
Test: Build an OTA updater (m updater) and call package_extract_file().

Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Add two functions libziparchive that libminzip has. And create
corresponding unit tests.
1. Open a zip archive from a memory mapped region.
2. A new writer that takes a call back function pointer.
(Used by the OTA updater to stream the data.)

Test: Open the crash.apk and libziparchive reports the offset error as expected.

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.

This allows someone to stream the data out of a zip archive
instead of extracting to a file or to memory.
Included in this change is a small cleanup of the makefile.

The code does not handle an edge case where writing a compressed
image can overflow the avail_out data when doing a flush. Add a
loop to keep writing the data while deflate indicates that it doesn't
have enough space to write out the compressed data during the flush.

The ZipWriter implementation exposes a stateful interface that allows
bytes of data to be streamed in as they arrive. ZipEntries can be
compressed and/or aligned on a 32-bit boundary for mmapping at runtime.

libziparchive).
