ProcessController: fix bars height computation

The previous code used a fixed margin, which would lead to too small
bars with small font sizes (the bar content would not even be visible).

Instead, use the font height as the base for the bar height, which
allows us to use the same code everywhere, no matter the menu item
height (which can vary depending on if there is an icon, etc)

Fixes #15391.

ProcessController: Fixed bars so they are aligned in center and scale
with the selected fonts

Deskbar: Resizable tray

* Adds max width and height arguments to
instantiate_deskbar_(item|entry).
* Old applications just stay with a 16x16 scaled icon, though.
* All used apps within the repository are converted to the new call
besides the input_server input method icon (that will need further
API changes in the input_server).

kernel, libroot: Introduce new API for obtaining system info

apps, kernel: Remove B_MAX_CPU_COUNT

Improve ProcessController<->Debugger integration.

- Clicking on a team item in Threads and CPU Usage now offers the option
to debug the team in addition to killing it.
- Both the aforementioned option and the previously existing thread
debugging option now invoke Debugger directly instead of simply
invoking debug_server via debug_thread().

Implements #9768.

Fix BAboutWindow lifecycle

BAboutWindow returned false in QuitRequested in order to hide instead of closing.
Not only this keeps a BLooper running for a rarely used window, but it also
prevents quitting an application in the window was not destroyed first.

* Remove aforementioned QuitRequested method,
* Add a static GetWindow method that returns the existing about window, if there
is one, or creates one if there is not. A boolean can be set to tell the caller
what happened,
* Adjust all callers to use that new method, instead of managing the window themselves.

Update copyright info for ProcessController

Bring AboutRequested() method back, not sure why I removed it.

Set the about window object to NULL on close or quit.

Pass the BHandler object that opened the about window to BAboutWindow.
When the window closes, send a kAboutWindowClosed message back to the
handler. This allows the handler to set the variable to NULL.

Implement the new about dialog constructor in all apps that use it.
Remove the old constructor. This now works reliably for all cases I
tested without crashing and does the right thing on close. The setup
and teardown is a bit more complicated than I wanted though.
Unfortunately this seems to be necessary when not using a BAlert.

Fetching the app icon does not work reliably yet. This is because for
replicants the app may not be running. I may have to pass the icon in
instead of grabbing it from the signature.

Removed code for using Pulse's colors. Minor changes to About window. Renamed menuitems Launch Tracker/Deskbar to Restart Tracker/Deskbar.

* Moved "install to Deskbar" alert into the application.
* If you install ProcessController to the Deskbar after startup, its window
is not opened anymore.
* When you install ProcessController, the Deskbar is only restarted if needed;
this can probably be removed completely under Haiku.
* Renamed some menu items.
* Removed "Use Pulse's settings" menu item.
* Fixed remaining issues from bug #633 as far as ProcessController was concerned.
* Removed unused source files.
* Big cleanup, even though there could be done much much more.
* Compacted the source files a bit, merged PCView.cpp and PCView2.cpp to
ProcessController.cpp to match the name of the class.
* Renamed PCUtils.{cpp|h} to Utilities.{cpp|h}
