This patch adds a new script -
`//browser_patches/firefox/repack-juggler.mjs`
This script lets you test Firefox changes if they are Juggler-specific
without firefox checkout / compilation.
The `repack-juggler.mjs` script does the following:
- downloads the latest build of Firefox-with-juggler
- finds an `omni.ja` file with Juggler files inside
- replaces juggler in omni.ja with the current juggler files in the index
The new message is much more prominent in the logs:
```

Before that it actually didn't install all needed dependencies and failed after that when starting the compiler suite. WebKit also installs dependencies with apt, so it should be fine to install them on OS level.
- to read post data of requests, we have to read stream
- to restore the stream later on, we have to rewind it back
- however, if the stream is large enough, it cannot be rewound back
This patch starts cloning post data streams if possible to avoid
back-rewinding them later on.
