Bump version to 4.56.4

This is not an illegal state, as the remote side could have hung-up
a microsecond before the local side tries to deny the call.

-Building Signal
-===============
-
-Basics
-------
-
-Signal uses [Gradle](http://gradle.org) to build the project and to maintain
-dependencies.  However, you needn't install it yourself; the
-"gradle wrapper" `gradlew`, mentioned below, will do that for you.
-
-Building Signal
----------------
-
-The following steps should help you (re)build Signal from the command line.
-
-1. Checkout the Signal-Android project source with the command:
-
-        git clone https://github.com/signalapp/Signal-Android.git
-
-2. Make sure you have the [Android SDK](https://developer.android.com/sdk/index.html) installed.
-3. Ensure that the following packages are installed from the Android SDK manager:
-    * Android SDK Build Tools (see buildToolsVersion in build.gradle)
-    * SDK Platform (All API levels)
-    * Android Support Repository
-    * Google Repository
-4. Create a local.properties file at the root of your source checkout and add an sdk.dir entry to it.  For example:
-
-        sdk.dir=/Application/android-sdk-macosx
-
-5. Using Java 8 
-
-6. Execute Gradle:
-
-        ./gradlew build
-
-Visual assets
-----------------------
-
-Source assets tend to be large binary blobs, which are best stored outside of git repositories. Some source files are SVGs that can be auto-colored and sized using a tool like [android-res-utils](https://github.com/sebkur/android-res-utils).
-
-Sample command for generating our audio placeholder image:
-
-```bash
-pngs_from_svg.py ic_audio.svg /path/to/Signal/res/ 150 --color #000 --opacity 0.54 --suffix _light
-pngs_from_svg.py ic_audio.svg /path/to/Signal/res/ 150 --color #fff --opacity 1.00 --suffix _light
-```
-
-Setting up a development environment
-------------------------------------
-
-[Android Studio](https://developer.android.com/sdk/installing/studio.html) is the recommended development environment.
-
-1. Install Android Studio.
-2. Open Android Studio. On a new installation, the Quickstart panel will appear. If you have open projects, close them using "File > Close Project" to see the Quickstart panel.
-3. From the Quickstart panel, choose "Configure" then "SDK Manager".
-4. In the SDK Tools tab of the SDK Manager, make sure that the "Android Support Repository" is installed, and that the latest "Android SDK build-tools" are installed. Click "OK" to return to the Quickstart panel.
-5. From the Quickstart panel, choose "Checkout from Version Control" then "git".
-6. Paste the URL for the Signal-Android project when prompted (https://github.com/signalapp/Signal-Android.git).
-7. Android studio should detect the presence of a project file and ask you whether to open it. Click "yes".
-9. Default config options should be good enough.
-9. Project initialisation and build should proceed.
-
-Contributing code
------------------
-
-Code contributions should be sent via github as pull requests, from feature branches [as explained here](https://help.github.com/articles/using-pull-requests).
-
-Mailing list
-------------
-
-Development discussion happens on the whispersystems mailing list.
-[To join](https://lists.riseup.net/www/info/whispersystems)
-Send emails to whispersystems@lists.riseup.net
