[8] Request for review: 7149913 [macosx] Deadlock in LWTextComponentPeer

[Sergey Bylokhov]

Hi Everyone,
This is a forward port from jdk 7u4:
http://hg.openjdk.java.net/jdk7u/jdk7u4-dev/jdk/rev/91ede930328c

Deadlock happens when 2 threads lock delegateLock and DefaultCaret 
object in different order. Removed code initially was added to stop 
recursion between paintPeer and addDirtyRegion( 
repaintPeer()->paintPeer()->print()->addDirtyRegion()->repaintPeer()-> 
etc), but it is impossible now because repaintPeer() asynchronous.
