'for in' is much faster than Object.keys() and since the events object is ours, we know
that we don't need to worry about prototypically inherited properties so we can skip
expensive hasOwnProperty check.

`for in` is much faster than `Object.keys()` but `for in` includes properties from the prototype.

All the uses of shallowCopy don't deal with objects with heavy prototypes, except for Attributes instances
in $compile.
For this reason it's better to special-case Attributes constructor and make it do it's own shallow copy.
This cleans up the Attribute/$compile code as well.
Functions with try/catch block can't be optimized, so we can
move the try/catch block into a tiny fn and make it possible for the
complex nodeLinkFn to get optimized.
This even is fired purely within jqLite/jQuery so it doesn't make sense to register DOM listener here.
6% improvement in large table benchmark for both creation and destruction
We no longer have a need for this feature that was added to primarily support
$watchGroup (see previous commit).
BREAKING CHANGE: deregisterNotifier callback for $watch is no longer available
This api was available only in the last few 1.3 beta versions and is not
very useful for applications, so we don't expect that anyone will be affected
by this change.
Instead of using a counter and an extra watch, just schedule the reaction function via .
This gives us the same/similar ordering and coalecsing of updates as counter without the extra
overhead. Also the code is easier to read.
Since interpolation uses watchGroup, this change additionally improves performance of interpolation.
In large table benchmark digest cost went down by 15-20% for interpolation.
Closes#8396
Some libraries (like jQuery UI) patch jQuery.cleanData as well. This commit
makes Angular work correctly even if such external patching was done after
the Angular one.
Fixes#8471
Add a $route#updateParams method for changing the current route
parameters without having to build a URL and call $location#path.
Useful for apps with a structure involving programmatically moving
between pages on the current route, but with different :param
values.
Properties in the object passed to $route.updateParams() will be
added to the location as queryParams if not contained within the
route's path definition.
