Rockbox Utility: Replace OSDaB Zip with QuaZip.

Browse source 
This change fixes problems with zip files created with newer zip utilities (a
known issue is the iLike theme). QuaZip also allows better feedback during
operations without changing the imported code. Additionally Rockbox Utility and
the Theme Editor are now both using QuaZip; currently Rockbox Utility uses a
copy of the sources, merging them later is planned.

/* crypt.h -- base code for crypt/uncrypt ZIPfile
Version 1.01e, February 12th, 2005
Copyright (C) 1998-2005 Gilles Vollant
This code is a modified version of crypting code in Infozip distribution
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
If you don't need crypting in your application, just define symbols
NOCRYPT and NOUNCRYPT.
This code support the "Traditional PKWARE Encryption".
The new AES encryption added on Zip format by Winzip (see the page
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
Encryption is not supported.

/** \class QuaZip quazip.h <quazip/quazip.h>
* This class implements basic interface to the ZIP archive. It can be
* used to read table contents of the ZIP archive and retreiving
* information about the files inside it.
*
* You can also use this class to open files inside archive by passing
* pointer to the instance of this class to the constructor of the
* QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*)
* for the possible pitfalls.
*
* This class is indended to provide interface to the ZIP subpackage of
* the ZIP/UNZIP package as well as to the UNZIP subpackage. But
* currently it supports only UNZIP.
*
* The use of this class is simple - just create instance using
* constructor, then set ZIP archive file name using setFile() function
* (if you did not passed the name to the constructor), then open() and
* then use different functions to work with it! Well, if you are
* paranoid, you may also wish to call close before destructing the
* instance, to check for errors on close.
*
* You may also use getUnzFile() and getZipFile() functions to get the
* ZIP archive handle and use it with ZIP/UNZIP package API directly.
*
* This class supports localized file names inside ZIP archive, but you
* have to set up proper codec with setCodec() function. By default,
* locale codec will be used, which is probably ok for UNIX systems, but
* will almost certainly fail with ZIP archives created in Windows. This
* is because Windows ZIP programs have strange habit of using DOS
* encoding for file names in ZIP archives. For example, ZIP archive
* with cyrillic names created in Windows will have file names in \c
* IBM866 encoding instead of \c WINDOWS-1251. I think that calling one
* function is not much trouble, but for true platform independency it
* would be nice to have some mechanism for file name encoding auto
* detection using locale information. Does anyone know a good way to do
* it?

/** \class QuaZipFile quazipfile.h <quazip/quazipfile.h>
* This is the most interesting class. Not only it provides C++
* interface to the ZIP/UNZIP package, but also integrates it with Qt by
* subclassing QIODevice. This makes possible to access files inside ZIP
* archive using QTextStream or QDataStream, for example. Actually, this
* is the main purpose of the whole QuaZIP library.
*
* You can either use existing QuaZip instance to create instance of
* this class or pass ZIP archive file name to this class, in which case
* it will create internal QuaZip object. See constructors' descriptions
* for details. Writing is only possible with the existing instance.
*
* \section quazipfile-sequential Sequential or random-access?
*
* At the first thought, QuaZipFile has fixed size, the start and the
* end and should be therefore considered random-access device. But
* there is one major obstacle to making it random-access: ZIP/UNZIP API
* does not support seek() operation and the only way to implement it is
* through reopening the file and re-reading to the required position,
* but this is prohibitely slow.
*
* Therefore, QuaZipFile is considered to be a sequential device. This
* has advantage of availability of the ungetChar() operation (QIODevice
* does not implement it properly for non-sequential devices unless they
* support seek()). Disadvantage is a somewhat strange behaviour of the
* size() and pos() functions. This should be kept in mind while using
* this class.

* \a zip is the pointer to the existing QuaZip object. This
* QuaZipFile object then can be used to read current file in the
* \a zip or to write to the file inside it.
*
* \warning Using this constructor for reading current file can be
* tricky. Let's take the following example:
* \code
* QuaZip zip("archive.zip");
* zip.open(QuaZip::mdUnzip);
* zip.setCurrentFile("file-in-archive");
* QuaZipFile file(&zip);
* file.open(QIODevice::ReadOnly);
* // ok, now we can read from the file
* file.read(somewhere, some);
* zip.setCurrentFile("another-file-in-archive"); // oops...
* QuaZipFile anotherFile(&zip);
* anotherFile.open(QIODevice::ReadOnly);
* anotherFile.read(somewhere, some); // this is still ok...
* file.read(somewhere, some); // and this is NOT
* \endcode
* So, what exactly happens here? When we change current file in the
* \c zip archive, \c file that references it becomes invalid
* (actually, as far as I understand ZIP/UNZIP sources, it becomes
* closed, but QuaZipFile has no means to detect it).
*
* Summary: do not close \c zip object or change its current file as
* long as QuaZipFile is open. Even better - use another constructors
* which create internal QuaZip instances, one per object, and
* therefore do not cause unnecessary trouble. This constructor may
* be useful, though, if you already have a QuaZip instance and do
* not want to access several files at once. Good example:
* \code
* QuaZip zip("archive.zip");
* zip.open(QuaZip::mdUnzip);
* // first, we need some information about archive itself
* QByteArray comment=zip.getComment();
* // and now we are going to access files inside it
* QuaZipFile file(&zip);
* for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
* file.open(QIODevice::ReadOnly);
* // do something cool with file here
* file.close(); // do not forget to close!
* }
* zip.close();

**************** ******* ******************************************************
detailed description
--------------------
Meet a couple of pure-Qt/C++ classes capable of handling PKZIP 2.0 compatible zip archives.
This is not a "port" of some other existing implementation, everything has been written from scratch (althought some code was actually inspired by existing public domain projects) and it's all pure C++/Qt. Please note that this is not a complete stand-alone library, it's just a bunch of classes. You will have to add them to your project and modify them to best fit your needs.
It supports basic features like file extraction and compression (with optional password encryption) and archive comments. There are methods to extract single files or the whole archive and methods to compress the contents of a whole directory. Nevertheless, it should be quite trivial to add other features. The public API only has a few methods because this is what I was looking for. This does not mean you can't write a few more lines of code (it really shouldn't take more than a few lines!) to add more features.
The classes are great if you only need to use the PKZIP format for loading/saving your application's data. Just remember that you will need to customize a few parts of the code, i.e. to add your own password retrieval method.
zlib is used for actual compression and decompression.
Please refer to the example application's main.cpp file or to the class comments in the source files for details and more usage examples.
history
-------
2008-09-97 - Bug fix: end of central directory was sometimes not being found when the archive had a comment.
2007-02-01 - New IgnorePaths compression option and two more "addDirectoryContents()" convenience methods to use this option.
2007-01-28 - Major changes:
- Bug fix: there was a big problem with directory names.
- API changes: the Zip::addDirectory() method is now easier to use.
The password can now be set using a setPassword() method and a new flag allows to preserve absolute paths.
- Added an "encrypted" flag to the Unzip::ZipEntry struct.
- Removed QObject inheritance. Internationalization is now achieved through QCoreApplication::translate().
2006-11-30 - A good part of the UnZip class has been rewritten. Zip entries with a Data Descriptor (like OpenOffice files) are now correctly parsed; some minor API changes and bug fixes; new features: comments, zip entry list, skip paths unzip option
2006-11-24 - Bug fix. An additional directory was being created for some files in the root directory
2006-10-23 - Minor API changes; QIODevice support added; better binary compatibility; "long long" issue with older compilers solved
2006-06-09 - Minor API changes
2005-10-03 - First public release
features
--------
Pure C++/Qt based, clean & oo implementation.
Retrieve archive contents information before extracting any file.
Fast (but less robust with corrupt archives) parsing of the ZIP file format.
Traditional PKWARE password encryption (strong encryption as introduced by PKZip versions 5.0 and later is NOT available).
Support for archive comments.
missing features and restrictions
---------------------------------
Needs to be modified to fit into an existing project (i.e.: you might need to add your own password handling routine).
Weak support of corrupted archives (althought some files could be extracted even if the archive is corrupted).
No support for filesystem specific features like unix symbolic links.
No support for spanned archives.
No support for strong encryption or features introduced after PKZIP version 2.0 (see the PKWARE specs for details).
requirements
------------
Qt version 4.0.x or later
zlib library
