Media: Show alert while media services restart

Media: Improve both notifications and quit mechanism

* Media is now waiting for media_server to start if the window
is closed before to finish, this was proposed by stippi.
* Moved out anything related to notifications as they are now
managed by the media_kit.
* Solved some TODOs and minor issues too.

Media: Display alert before to quit when restarting

* Fixes 10770.
* While more complex solutions are proposed, i think
of it as a way to get out of an eventual deadlock or
to protect from accident close.

Remove now unneeded MediaAlert class.

Media Prefs: rework the BNotification code

* Factor out the notification sending in a single method
* Tweak the "progress" values so the progress bar goes from 0 to 100% in
order, and only once, during the restart
* Remove one notification that was needlessly sent twice
* Some other small cleanups

Final fix for #8171.

Media service restart is now using BNotification. Fixes 8171.

Integrate MIDI settings with the Media preflet.
More or less working.

Cleanup.

* Sort methods like they are declared in the header.
* Fixed a number of coding style violations and other oddities.

In Media preflet: add an ItemWidth() method to MediaListItem::Renderer, which tells us how much space is needed onscreen for a MediaListItem. Use the new ItemWidth() method in MediaListItem::Update() to set our width. Add a MediaWindow::_UpdateListItemMinSize() method that uses the items' width to calculate the new explicit min width of our list view. This fixes a problem I saw with localized strings in the listview not being fully displayed.

In Media preflet:
* Modify MediaListItem to use the visitor pattern
* Use the visitor pattern for comparison of MediaListItem subclassed objects
* Use the visitor pattern in MediaWindow to propagate changes to NodeListItems.
* Rename and/or remove some message constants
* Rename SettingsItem class to NodeMenuItem
* Rename Settings2Item class to ChannelMenuItem
* Derive SettingsView from BGridView, and make it an abstract base class for two new classes, AudioSettingsView and VideoSettingsView.
* Have the SettingsView subclasses handle messages originating from their children (for the most part).
* Use a BCardLayout to hold our Audio/Video SettingsViews and our instantiated node view (when applicable).
* small changes

In Media preflet:
* Refactor MediaListItem into four/five classes:
* MediaListItem : abstract base class which provides an interface for
MediaWindow and MediaListItem subclasses
* NodeListItem : list item for media nodes
* DeviceListItem : list item for audio/video settings (device selection)
* MixerListItem : list item for the audio-mixer
* MediaListItem::Renderer : does the drawing of MediaListItems, which supply
render paramaters via a 'SetRenderParamaters()' method.
* Comparison of MediaListItems (for sorting) is done via double-dispatch
* MediaListItem provides a pure virtual AlterWindow() method, which removes the
burden of distinguishing between different behaviours from MediaWindow.
* Add methods to MediaWindow for the MediaListItems to call in their
AlterWindow() implementation, eg. SelectNode()
* Seperate code into these methods, as well as a few private utility methods.
* Add a RAII-style 'SmartNode' nested class for MediaWindow, which handles
watching/unwatching allocating/deallocating of media_nodes

In Media preflet:
* Move icons to resource file.
* Add MediaIcons class to handle loading and storing the icons.
* Use a MediaIcons object in place of a BList for passing icons to our list items.
* Add IconHandles.h to hold an enum for identifying icons in/from our resource file.
* style fixes


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39180 a95241bf-73f2-0310-859d-f6bbb57e9c96

Update Media prefs to use BObjectList in place of BList + a few style fixes.

In media preferences:
* remove custom 'BarView' class, and replace it with BSeparatorView.
* remove BStringVIew for displaying titles, our BSeparatorView does this now.
* Have the BSeparatorView always draw, BarView was only drawn sometimes.

This helps stabilise the window size, cleans up the code and looks nicer, in my opinion.

Big style cleanup in preparation for refactoring the media preflet and tackling #6544.
Fix one use of sscanf(...) > 0, where it ought to be sscanf(...) == 4.
Otherwise, no functional changes intended.
