many dojox/mvc doh tests are failing

Many of the dojox/mvc doh tests are failing, it seems to be related to the changes for #16693

asudoh has a potential workaround in this pull request: ​https://github.com/edchat/dojox_mvc/pull/73

But bill has indicated that he is planning to rollback his changes for #16693 for 1.9, so I am not going to merge the workaround for 1.9

In [30659]:

Rollback [30599] and part of [30598]. They break code like dojox/mvc that dynamically adds setters to an instance, and also have a problem where defining a custom getter disables the code that automatically maps widget properties to DOMNode attributes (failing in dojox/mvc/Element.js for value property). As in 1.8, the dynamically added setters won't be automatically called on widget creation unless the property is specified as a parameter to the widget constructor. Refs #16693 and fixes #16738 !strict.

Also rolling back workaround code from [30639], refs #16737.

For 2.0 I'll probably have an API to add properties (with getters or setters) to an instance, and either remove or rearchitect how properties are automatically mapped to DOMNode attributes.
