Previous behavior: `transferPropsTo(<div style={{color: 'red'}} />)` would get `color` overriden if we transfer in a `style={{color: 'blue'}}`. This is inconsistent with how other props are transfered.
This simply reverses the order of arguments.

This makes it a little easier to add SVG properties. It also makes use of that injection that we claim is easy to use and will likely start playing a bigger part soon.
Closes#1009
We're now trying to access document directly at require time. Wrapping in a function prevented that before. But we can simply check what environment we're in first.
React components have _mountIndex, that looks like it is their order in DOM.
If you swap 2 elements in DOM, their order in children array isn't changed, but their _mountIndex is
There is no point in doing the feature detection on every call, unless there is an IE bug where it is not sure about which support for selection it has (totally plausible).
Adds a PropType that checks for proper use of the ReactLink API and optionally validates the type of value passed in via the link. Basically, it's a wrapper around PropTypes.shape that hides the implementation of ReactLink.
The `updatedChildren[j].parentNode.removeChild(updatedChildren[j]);` line below can fail if (1) we're moving/moving the same node twice or (2) the node we're looking for is gone completely. This makes it easier to distinguish between the two cases.
Perf shouldn't be a concern here because this is DOM code and invariants are fast in comparison.
Test Plan: grunt test
The report itself is more or less useful because it detects stuff like
big objects (e.g. CSSProperty) as being too complicated. Furthermore, afaik
nobody refactors the code based on what the report says =).
Fixes#1408.
Test Plan: Copy each code snippet into jsbin; type in the text box successfully; click the button and see the input clear (and in the second example, get focused).
8855d6153e gave more accurate error messages for date and regexp by returning 'date' and 'regexp' respectively from `getPropType`.
However, for the object primitive check, which compares the instance passed with `getPropType's` return string, `object` !== 'date'.
This adds special hanlding for those.
