Refactor DevFS so that it's easier to add new types of content such as kernel code * add tests for DevFS package scanning * add tests for DevFS over VMService protocol * which covers _DevFSHttpWriter and ServiceProtocolDevFSOperations * replace AssetBundleEntry and DevFSEntry with DevFSContent * refactor to cleanup common code and replace some fields with locals * rework .package file generation refactor away DevFSOperations.writeSource * only update .package file if it has changed * only write/delete/evict assets that have been changed/removed
