[8] Review request for 7124213 and 7160627

[Sergey Bylokhov]

Hi Everyone,
Please review the fix for:
7124213 [macosx] pack() does ignore size of a component; doesn't on the 
other platforms.
7160627 [macosx] TextArea has wrong initial size

Description of main changes:
All our components were split into 3 groups:
  - Uses getPreferedSize()/getMinimumSise from swing delegetes.
  - Uses its own size as a preferedSize/minimumSize.
  - Uses its own implementation.

Notes:
LWContainerPeer is subclass of LWCanvasPeer now. We can share buffers 
methods in LWCanvasPeer and LWWindowPeer.
All magic/system constants were removed. Now we relies on default look 
and feel as much as possible.
