Subject: [PATCH] Add extensibility point for passing additional args to
 packager
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend `react-native-xcode.sh` to allow passing of additional args to
bundle command. This is useful if you want to generate source maps for
example.

Here is an example that modifies the “Bundle React Native code and
images” script phase:

```sh
export NODE_BINARY=node
export EXTRA_PACKAGER_ARGS="--sourcemap-output ${SRCROOT}/build/main.jsbundle.map"

./react-native-xcode.sh

```

Android’s `build.gradle` already have this extensibility point in the name
of:
```gradle
project.ext.react = [
    extraPackagerArgs: [
    ]
]
```
