Subject: [PATCH] package/ci: build for iOS on Travis CI.

What's done:
 * The build matrix now has four targets -- Linux desktop, OSX desktop,
   iOS GLES2 and iOS GLES3.
 * Putting the commands into separate bash scripts, which are called
   based on what's the actual build matrix item.
 * Displaying *all* test output (colored) for visual verification.
