/**
 * WordPress Filesystem Class for implementing SSH2
 *
 * To use this class you must follow these steps for PHP 5.2.6+
 *
 * {@link http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes}
 *
 * Compile libssh2 (Note: Only 0.14 is officially working with PHP 5.2.6+ right now, But many users have found the latest versions work)
 *
 * cd /usr/src
 * wget https://www.libssh2.org/download/libssh2-0.14.tar.gz
 * tar -zxvf libssh2-0.14.tar.gz
 * cd libssh2-0.14/
 * ./configure
 * make all install
 *
 * Note: Do not leave the directory yet!
 *
 * Enter: pecl install -f ssh2
 *
 * Copy the ssh.so file it creates to your PHP Module Directory.
 * Open up your PHP.INI file and look for where extensions are placed.
 * Add in your PHP.ini file: extension=ssh2.so
 *
 * Restart Apache!
 * Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp  exist.
 *
 * Note: As of WordPress 2.8, this utilizes the PHP5+ function `stream_get_contents()`.
 *
 * @since 2.7.0

// Presentation :
//   PclZip is a PHP library that manage ZIP archives.
//   So far tests show that archives generated by PclZip are readable by
//   WinZip application and other tools.
//
// Description :
//   See readme.txt and http://www.phpconcept.net
//
// Warning :
//   This library and the associated files are non commercial, non professional
//   work.
//   It should not have unexpected results. However if any damage is caused by
//   this software the author can not be responsible.

// ----- File list separator
  // In version 1.x of PclZip, the separator for file list is a space
  // (which is not a very smart choice, specifically for windows paths !).
  // A better separator should be a comma (,). This constant gives you the
  // ability to change that.
  // However notice that changing this value, may have impact on existing
  // scripts, using space separated filenames.
  // Recommended values for compatibility with older versions :
  //define( 'PCLZIP_SEPARATOR', ' ' );
  // Recommended values for smart separation of filenames.

  // 0 : PclZip Class integrated error handling
  // 1 : PclError external library error handling. By enabling this
  //     you must ensure that you have included PclError library.

// ----- Optional static temporary directory
  //       By default temporary files are generated in the script current
  //       path.
  //       If defined :
  //       - MUST BE terminated by a '/'.
  //       - MUST be a valid, already created directory

// ----- Optional threshold ratio for use of temporary files
  //       Pclzip sense the size of the file to add/extract and decide to
  //       use or not temporary file. The algorithm is looking for
  //       memory_limit of PHP and apply a ratio.
  //       threshold = memory_limit * ratio.
  //       Recommended values are under 0.5. Default 0.47.

  //   Attributes must not be accessed directly.
  // Methods :
  //   PclZip() : Object creator
  //   create() : Creates the Zip archive
  //   listContent() : List the content of the Zip archive
  //   extract() : Extract the content of the archive
  //   properties() : List the properties of the archive

    // The class can then disable the magic_quotes and reset it after

// --------------------------------------------------------------------------------
  // Function : PclZip()
  // Description :
  //   Creates a PclZip object and set the name of the associated Zip archive
  //   filename.
  //   Note that no real action is taken, if the archive does not exist it is not
  //   created. Use create() for that.

  //   create($p_filelist, $p_option, $p_option_value, ...)
  // Description :
  //   This method supports two different synopsis. The first one is historical.
  //   This method creates a Zip Archive. The Zip file is created in the
  //   filesystem. The files and directories indicated in $p_filelist
  //   are added in the archive. See the parameters description for the
  //   supported format of $p_filelist.
  //   When a directory is in the list, the directory and its content is added
  //   in the archive.
  //   In this synopsis, the function takes an optional variable list of
  //   options. See below the supported options.
  // Parameters :
  //   $p_filelist : An array containing file or directory names, or
  //                 a string containing one filename or one directory name, or
  //                 a string containing a list of filenames and/or directory
  //                 names separated by spaces.
  //   $p_add_dir : A path to add before the real path of the archived file,
  //                in order to have it memorized in the archive.
  //   $p_remove_dir : A path to remove from the real path of the file to archive,
  //                   in order to have a shorter path memorized in the archive.
  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
  //                   is removed first, before $p_add_dir is added.
  // Options :
  //   PCLZIP_OPT_ADD_PATH :
  //   PCLZIP_OPT_REMOVE_PATH :
  //   PCLZIP_OPT_REMOVE_ALL_PATH :
  //   PCLZIP_OPT_COMMENT :
  //   PCLZIP_CB_PRE_ADD :

  //   The list of the added files, with a status of the add action.

  //   The properties of each entries in the list are (used also in other functions) :
  //     filename : Name of the file. For a create or add action it is the filename
  //                given by the user. For an extract function it is the filename
  //                of the extracted file.
  //     stored_filename : Name of the file / directory stored in the archive.
  //     size : Size of the stored file.
  //     compressed_size : Size of the file's data compressed in the archive
  //                       (without the headers overhead)
  //     mtime : Last known modification date of the file (UNIX timestamp)
  //     comment : Comment associated with the file
  //     folder : true | false
  //     index : index of the file in the archive
  //     status : status of the action (depending of the action) :
  //              Values are :
  //                ok : OK !
  //                filtered : the file / dir is not extracted (filtered by user)

  //                write_protected : the file can not be extracted because a file
