Two variables were added to ReadOnlyArchiveInterface: A boolean
describing whether the archive is multi-volume and an int used for
storing number of volumes. Two corresponding Q_PROPERTY's were added to
Archive which fetch the info from ReadOnlyArchiveInterface.

The detection of multi-volume archives was fixed in cli7z.

The information is displayed in PropertiesDialog and will be used when
implementing support for creating multi-volume archives.

This should have been part of commit 27e5167b.

We never set this option and because of this there is a lot of unused code (e.g. all the `RootNodeSwitch` stuff).

Digging in the history, the last time that this option was set was in commit 10bc72f4.
This means that this option is fully superseded by `fileNodeRootPair` and we can safely discard all this unused code.

Ark was ignoring the password prompt, resulting in an endless DeleteJob.
This is simply fixed by using the PasswordSwitch, like in other jobs.

Add a TestJob and associated action in Part. Test functionality is
enabled in plugin json files, currently for clizip, clirar and cli7z.
Test results are displayed simply as success/failure in a KMessageBox.

Testing password-protected archives will currently result in an
errorbox, due to these archives potentially having different passwords
for each file and hence multiple password prompts might pop up.

Libarchive does not support testing archives.

Support was added for editing comments in supported archive types
(currently only RAR). A new bool was added to plugin json files
("SupportsWriteComment") to indicate support. A new action was added and
is found in Archive menu. The editing of comment is done in the same
QPlainTextEdit used to display comments before. When user modifies
comment, a KMessageWidget pops up with a "Save" button. Actual saving of
comment to archive is achieved by a new job type: CommentJob.

Support for passing compression level was implemented for the cli-based
plugins. The user-interface elements to actually set the level are not
yet in place.

Differential Revision: D1268

Previously, Ark didn't handle "no space left" error messages from the
cliplugins. This resulted in either the gui being "busy" continously
(clizip), or that the user didn't get any indication that there was a
problem extracting the archive (cli7z and clirar).

This commit adds a pattern (DiskFullPatterns) for catching these errors.
An errorbox is then displayed to the user. Some of the programs used in
the cliplugins, such as 7z v9.38, doesn't output a specific message,
but then a generic "Extraction failed" message is displayed instead.

The ark plugins are now ported to the new KPluingLoader loading mechanism.
The main advantage is that we now save a call to the Syscoca service trader,
since the plugins are installed in a private 'kerfuffle' subdirectory of the
system plugins folder.

In order to be found by KPluginLoader, a plugin has to embed its metadata
defined in a .json file. We convert the existing .desktop files to .json at build time, when possible.
Otherwise we use directly .json metadata files (e.g. for clirar or cliunarchiver).

The libarchive plugin had to be split in two different plugins, one for the
read-only mimetypes and another one for the read-write ones. This is because
the old plugin was using two .desktop files, but the new plugins can only embed
a single .json file.

For more details, see task T923 on phabricator.

The overwrite prompt changed from p7zip version 9.38.1 to 15.09. Add
support for the new prompt. FileExistsExpression had to be changed
from QString to QStringList.

Also, got rid of unneeded CliInterface::checkForFileExistsMessage().
Just use CliInterface::checkForErrorMessage() instead.

This macro was introduced in ECM 5.14.0 and generates logging category
declarations. This removes the necessity of Q_LOGGING_CATEGORY calls in
cpp files. A header with Q_DECLARE_LOGGING_CATEGORY is automatically
generated, so the old logging.h file can be removed.

Also the identifier is now ARK everywhere, so all qCDebug() should be
qCDebug(ARK).

This bumps the required dep version for ECM to 5.14.0.

A new parameter was added to the Kerfuffle::CliInterfaceParameters enum
(called CorruptArchivePatterns), containing a list of regexps matching
output from CliPlugins when a corrupt archive is listed.

Due to the CliInterface not being able to launch a KMessageBox itself, a
query (LoadCorruptQuery) was added which launches a
KMessageBox::warningYesNo asking the user if he wants to try to load the
corrupt archive. This is useful because some files might still be
recoverable.

If the user answers no, loading of the archive is cancelled.

If the user answers yes the archive is loaded as usual, but to prevent
the user from trying to add/delete files from the corrupt archive (which
is likely to fail), the archive is set to readonly. This necessitated a
new private member in ReadOnlyArchiveInterface (m_isCorrupt) and
getter/setter functions. The setter function is used in
CliInterface::HandleLine, while the getter function is used in
ReadWriteArchiveInterface::isReadOnly().

Detect solid and multi-volume archives. For now, just store this info in
member variables and output to debug.

Remove some superfluous m_isUnrar5 checks.

For unrar 5, go back to ParseStateHeader when finding a line that starts
with "Archive: ". This is needed for multi-volume archives.

This function is overridden in the individual CliPlugins and resets
parsing variables, such as ParseState, m_comment, etc. This is needed
because an archive can be listed several times without the plugin being
reloaded, e.g. after adding files. This can result in e.g. comments
being appended to themselves or parsing being started in the wrong
ParseState.
resetParsing() is called in CliInterface::list(), before running the
list process.

Unrar 4 prints "Solid archive" instead of just "Archive" for solid
archives, i.e. archives compressed as a single continous data block
(compressing with the -s switch).

readListLine() is now very short. It simply checks the version of unrar
and calls line-handling functions specific for unrar 3/4 and 5 termed
handleUnrar4Line() and handleUnrar5Line(), respectively.

When the line-handling functions have completed parsing all the details
of an archive entry, they call an entry-handling function, either
handleUnrar4Entry() or handleUnrar5Entry().

The overwrite prompt changed in unrar 5 compared to unrar 3 and 4. This
commit adds support for the unrar 5 prompt. Unrar 5 has a multi-line
overwrite prompt, i.e. the last line of the overwrite prompt does not
contain the name of the existing file, which is needed by the
OverwriteQuery to display the filename to the user. This was solved by
storing the filename in a member variable m_storedFileName, so it is
available when the last line of the overwrite prompt is reached. To
capture the filename, a new parameter, FileExistsFileName, was added to
the CliInterfaceParameters enum.

7z also has a multi-line overwrite prompt, so previously the filename
was not displayed in the OverwriteQuery dialog. This is now fixed.

This is recommended by krazy2.

unrar-free is unmaintained and is far from feature-parity with
"non-free" unrar. Additionally, Ark's support for unrar-free has been
broken for a while.

Remove noisy debug output, e.g. from clirar that gets emitted for each
entry in an archive. This clutters the console output with alot of
not-so-useful info.

This feature allows Ark to create a password-protected archive from
scratch.
The 7z and rar plugins support both header encryption and entries-only
encryption, while the zip one supports only the latter.

An encrypted archive can be created through the CreateDialog (within Ark) or
through the AddDialog (from e.g. Dolphin).

RAR v3 and v4 output an extra line when an entry is a symlink. This line
contains the symlink target. Since we were not accounting for this extra
line before, our parser crashed.

Work around the issue by checking if we're listing a symlink and skipping an
extra line if so.

(cherry picked from commit 6d8bd57b)

It turns out there is some documentation on the RAR file format in
http://www.rarlab.com/technote.htm, so it is not true that the format is
undocumented.

While here, use the term "service header" instead of "subheader" as in the
file format documentation. It would make sense to rename the enum we use as
well, but it would clobber the history and git blame without much benefit.

I have never understood why this class was added in the first place,
and digging through the old commit history does not help much in this
regard.  It was mostly used as another way of doing signals and slots.

 * The calls in ArchiveInterface that called each observer method now
   just emit the signals declared in ReadOnlyArchiveInterface, and the
   observer methods in the Job classes are now slots.
 * ReadOnlyArchiveInterface::removeObserver() has been replaced with
   QObject::disconnect().

All the (few) unit tests we have still pass.
