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 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.

Contrary to the comment in AndroidConfig.h, mingw does have
__BEGIN_DECLS and __END_DECLS; you just have to #include <sys/cdefs.h>
first. Which is strictly true normally too, but you're going to
get it transitively with bionic or glibc.

since the struct is now used for other purposes. Also add some
comparator functions to the struct to simplify zip_archive.cc.
This is a follow-up CL for f1d3d3b247.

so that PackageManagerService can iterate over files with a
specific file extension like ".so".

It's important because entry names can be encoded in UTF-8 and can have \0
character in the middle.
Use vector instead of char* for prefix in IterationHandle.

Add new public method to allow checkisc if an archive has entry names encoded in
UTF-8. If not then they will be encoded in IBM PC character encoding.

in StartIteration. This method should always be called when the
iteration is over to make sure that we don't leak memory.

We would always write uncompressed data at offset 0 instead
of the current filedescriptor offset.
Also adds a unit-test & a clarifying comment on the API.

Extract zip file processing logic from libdvm into a
standalone library.
This library is a stricter than the libdvm library in
several ways:
- Duplicate zip entry names are now disallowed. Files with
such entries will fail to parse.
- We now verify CD file size information with the individual
file header information. (This was pointed out as a deficiency
of this implementation in past discussions.)
- We also add support for crc checking, which means we might
need to parse the optional data descriptor footer (if one
exists).
We also provide an API for iterating over the entries of
a zip file. This library is optimized for two use cases :
- Lookup for a single entry in the file, with the intention
of processing or extracting the data associated with that
entry
- Iterating over all entries in a file *and* processing
/ extracting their data.
