Rewrote documentation

Rewrote some copy to provide more context and link to more GL-related repos, including GL JS. Put the various SDKs in a table so we can show the various CI bot status images.

Integrated target list into the relevant documents. Rewrote large portions of iOS and OS X setup documentation to guide normal developers to more friendly places. Combined some Android documentation.

Moved SDK-specific documentation into platform/. Added a temporary readme in ios/ that points to the one in platform/ios/.

 # Mapbox GL Native
 
-[![Travis](https://api.travis-ci.org/mapbox/mapbox-gl-native.svg?branch=master)](https://travis-ci.org/mapbox/mapbox-gl-native/builds) [![Bitrise](https://www.bitrise.io/app/7514e4cf3da2cc57.svg?token=OwqZE5rSBR9MVWNr_lf4sA&branch=master)](https://www.bitrise.io/app/7514e4cf3da2cc57)
+A library for embedding interactive vector maps into native applications on multiple platforms. It takes stylesheets that conform to the [Mapbox GL Style Specification](https://github.com/mapbox/mapbox-gl-style-spec/), applies them to vector tiles that conform to the [Mapbox Vector Tile Specification](https://github.com/mapbox/vector-tile-spec), and renders them using OpenGL. [Mapbox GL JS](https://github.com/mapbox/mapbox-gl-js) is the WebGL-based counterpart, designed for use on the Web.
 
-An OpenGL-based renderer for [Mapbox Vector Tiles](https://www.mapbox.com/blog/vector-tiles), consisting of a C++ library for Linux and SDK bindings for iOS, Android, Node.js, and OS X.
+## The Mapbox GL ecosystem
 
-**This repository is for development on Mapbox GL Native itself.**
+This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a [GLFW](https://github.com/glfw/glfw)-based demo application for Ubuntu Linux and OS X. The SDKs target the usual languages on their respective platforms:
