Update .gitmodules for automated release src package creation

Introduce new "deprecated" value for status attribute.

We have two flavors of big source packages we need to produce:

qt-everywhere-* which needs to include:

 - essential
 - addon
 - preview
 - deprecated (e.g. qtscript and qtenginio for Qt5.6 release)

Installer only specific source package:

 - essential
 - addon

 The rest (deprecated, preview, ...) need to be shown as split src
 packages in the installer.

The above leads to the following changes:

qtscript: addon -> deprecated

 Needs to be part of big src packages but excluded from installer
 specific big source package.

qtenginio: obsolete -> deprecated

 We can't exclude this module from qt-everywhere src packages.

qtwayland: preview -> addon

 Needs to be part of installer specific big src package and the
 module status is not preview anymore.

-  ./init-repository [options]
+Options:
+  Global options:
 
-This script may be run after an initial `git clone' of Qt5 in order to check
-out all submodules.  It fetches them from canonical URLs inferred from the
-clone's origin.
+    --force, -f
+        Force initialization (even if the submodules are already checked
+        out).
 
+    --force-hooks
+        Force initialization of hooks (even if there are already hooks in
+        checked out submodules).
 
-=head1 OPTIONS
+    --quiet, -q
+        Be quiet. Will exit cleanly if the repository is already
+        initialized.
 
-B<Global options:>
+  Module options:
 
-=over
+    --module-subset=<module1>,<module2>...
+        Only initialize the specified subset of modules given as the
+        argument. Specified modules must already exist in .gitmodules. The
+        string "all" results in cloning all known modules. The strings
+        "essential", "addon", "preview", "deprecated", "obsolete", and
+        "ignore" refer to classes of modules; "default" maps to
+        "essential,addon,preview,deprecated", which corresponds with the
+        set of maintained modules and is also the default set. Module
+        names may be prefixed with a dash to exclude them from a bigger
+        set, e.g. "all,-ignore".
 
-=item --force, -f
+    --no-update
+        Skip the `git submodule update' command.
 
-Force initialization (even if the submodules are already checked out).
+    --branch
+        Instead of checking out specific SHA1s, check out the submodule
+        branches that correspond with the current supermodule commit. By
+        default, this option will cause local commits in the submodules to
+        be rebased. With --no-update, the branches will be checked out, but
+        their heads will not move.
 
+    --ignore-submodules
+        Set git config to ignore submodules by default when doing operations
+        on the qt5 repo, such as `pull', `fetch', `diff' etc.
 
-=item --force-hooks
+        After using this option, pass `--ignore-submodules=none' to git to
+        override it as needed.
 
-Force initialization of hooks (even if there are already hooks in checked out
-submodules).
+  Repository options:
 
+    --berlin
+        Switch to internal URLs and make use of the Berlin git mirrors.
+        (Implies `--mirror').
 
-=item --quiet, -q
+    --oslo
+        Switch to internal URLs and make use of the Oslo git mirrors.
+        (Implies `--mirror').
 
-Be quiet.  Will exit cleanly if the repository is already initialized.
+    --codereview-username <Gerrit/JIRA username>
+        Specify the user name for the (potentially) writable `gerrit' remote
+        for each module, for use with the Gerrit code review tool.
 
-=back
+        If this option is omitted, the gerrit remote is created without a
+        username and port number, and thus relies on a correct SSH
+        configuration.
 
+    --alternates <path to other Qt5 repo>
+        Adds alternates for each submodule to another full qt5 checkout.
+        This makes this qt5 checkout very small, as it will use the object
+        store of the alternates before unique objects are stored in its own
+        object store.
 
-B<Module options:>
+        This option has no effect when using `--no-update'.
 
-=over
+        NOTE: This will make this repo dependent on the alternate, which is
+        potentially dangerous! The dependency can be broken by also using
+        the `--copy-objects' option, or by running "git repack -a" in each
+        submodule, where required. Please read the note about the `--shared'
+        option in the documentation of `git clone' for more information.
 
-=item --module-subset=<module1>,<module2>...
+    --copy-objects
+        When `--alternates' is used, automatically do a "git repack -a" in

-Only initialize the specified subset of modules given as the argument. Specified
-modules must already exist in .gitmodules.
-The string "all" results in cloning all known modules. The default is the set of
-maintained modules.
-Module names may be prefixed with a dash to exclude them from a bigger set.
+        Note that this negates the disk usage benefits gained from the use
+        of `--alternates'.

+    --mirror <url-base>
+        Uses <url-base> as the base URL for submodule git mirrors.
 
-Skip the `git submodule update' command.
+        For example:
 
-=item --branch
+          --mirror user\@machine:/foo/bar/

-Set git config to ignore submodules by default when doing operations on the
-qt5 repo, such as `pull', `fetch', `diff' etc.
+        The mirror is permitted to contain a subset of the submodules; any
