BorderContainer: splitter max is broken

[Adam Peller]

In most of the test examples, you can drag the splitter beyond the edge of the next panel, which should not be allowed. In some cases, where there are only two panels across, you can drag it off the screen where it cannot come back.

(In [15022]) make measurements match test. Refs #7453

[Adam Peller]

(In [15023]) recalculate splitter constraints when opposite panel is resized. Refs #7453 !strict

[Adam Peller]

(In [15024]) recalculate splitter constraints when flag is set. Refs #7453 !strict

[Adam Peller]

(In [15025]) recalculate splitter constraints on resize. Refs #7453 !strict

[Adam Peller]

(In [15028]) Still not perfect with borders, padding, and gutters, but it might not be worth all those measurements. Otherwise, resizing constraints seem sane now. Fixes #7453 !strict

[15028] is causing errors on page unload (tested on IE, themeTester.html).

The counterpart of this.connect() is this.disconnect(), not dojo.disconnect(), but you don't need to call this.disconnect() (or dojo.disconnect()) at all, because it's automatically called on widget destroy. Also, the third argument to this.connect() should just be a string, not a dojo.hitch() call.

[Adam Peller]

(In [15029]) Remove unneeded dojo.disconnect. Fixes #7453 !strict

[Adam Peller]

(In [15031]) Fix args to this.connect. Fixes #7453 !strict

[Adam Peller]

(In [15113]) missing 'this'. Refs #7453, Fixes #7582 !strict
