Summary:
We had a classic integer underflow problem here. Before we would let you type endlessly when the text already exceeded the TextInput maxLength, now we only let you erase characters.
There is still a small problem with the TextInput: how do you handle when the value (set from JS) exceeds the maxLength? This could happen pragmatically, just by passing in a very large value or when changing maxLength (e.g. when changing from 4 to 3 digits in the case of a AMEX security code -> VISA security code).
Me and achen1 discussed firing onChange in these cases and truncating the number manually (to ensure JS's data model) was aware of the change but it seemed fraught with bugs and general weirdness in what the caller would expect to happen.

Summary:
This adds support for a controlled `selection` prop on `TextInput` on iOS (Android PR coming soon). This is based on the work by ehd in #2668 which hasn't been updated for a while, kept the original commit and worked on fixing what was missing based on the feedback in the original PR.
What I changed is:
- Make the prop properly controlled by JS
- Add a RCTTextSelection class to map the JS object into and the corresponding RCTConvert category
- Make sure the selection change event is properly triggered when the input is focused
- Cleanup setSelection
- Changed TextInput to use function refs to appease the linter
** Test plan **
Tested using the TextInput selection example in UIExplorer on iOS.
Also tested that it doesn't break Android.

This adds support to set the highlight color on TextInput on Android. See https://github.com/facebook/react-native/pull/5678 for the iOS implementation.
Note : We will merge these two properties with one name 'selectionColor' in a follow on diff, and may move it to a style.

Summary: The default value (to retain current behavior) is set to `true`. Setting the value to `false` will prevent the textField from blurring but still fire the `onSubmitEditing` callback. However, the `onEndEditing` callback will not be fired.

Summary:
This introduces event counts to make sure JS doesn't set out of date values on
native text inputs, which can cause dropped characters and can mess with
autocomplete, and obviates the need for the input buffering which added lag and
complexity to the component. Made sure to test simulated super-slow JS text
event processing to make sure characters aren't dropped, as well as typing
obviously correctable words and making sure autocomplete works as expected.
TextInput is now a controlled input by default without causing any issues for
most cases, so I removed the `controlled` prop.
Fixes selection state jumping by restoring it after setting new text values, so
highlighting the middle of some text in the new ReWrite example and hitting
space will replace that selection with an underscore and keep the cursor at a
sensible position as expected, instead of jumping to the end.
Ads `maxLength` prop to support the most commonly needed syncronous behavior:
preventing the user from typing too many characters. It can also be used to
prevent users from continuing to type after entering special characters by
changing it to the current length after a regex match. Made sure to verify it
works well with pasted input (including in the middle of existing text),
truncating it and collapsing the selection the same way it does on the web.
Fixes bug in TextEventsExample where it wouldn't show the submit and end events,
even though there were firing correctly.
