<Swing Dev> [9] Review Request: 8134947 [macosx] Various memory leaks in Aqua look and feel

[Sergey Bylokhov]

Hello.
Please review the fix for jdk9.
Initially I found this bug in JSpinner during my work on
JDK-7124397, after I covers other components in the test I found other 
cases in Aqua.

The problem is that some of UI delegates in Aqua does not follow the 
rules that they should removes all listeners/references in the 
uninstallUI method.

AquaCaret.java + related textui : this ui now updates the 
reference/listeners in install/deinstall instead of update it only once 
in the constructor.

AquaInternalFrameUI.java : code related to components removing was moved 
to uninstallComponents.

AquaSpinnerUI.java : see comments in the code.

AquaTabbedPaneUI.java : I force removing of the reference to the ui 
delegate from the timer.

I also tried to make a small cleanup and split longest lines only, 
otherwise in some cases I will have to update the whole files.

The follow bug for motif/synth l&f is filed: JDK-8135138
