This would allow adding entries from one zip archive into
a new one without copying, directly from a ZipString object

Enable -Wconversion (but not -Wsign-conversion). Fix up code. Handle
some actual error cases:
* too many files
* files too large

Update the powerof2 macro to one that is integer overflow safe.
This definition is the same one used by bionic, but cleaned up using
clang_format.
Unconditionally use this powerof2 macro, to ensure consistency across
all the build environments.
Test: compiles and boots

This allows us to remove libziparchive's dependency on libutils.

We change the GPB in the LocalFileHeader if the entry can not
have a trailing DataDescriptor. Make sure to patch the
CentralFileHeader to have the same bits set.
Modify ZipArchive to check that the data descriptor bit is consistent
between Central and Local file headers.

Older implementations of ZIP (Java's ZipInputStream) don't
like a Data Descriptor trailing after an uncompressed entry.
If the FILE is seekable, and the entry is uncompressed, seek
back to the header and write out the crc and sizes.

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.

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.

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.
