Previously these arguments were initialized in places which would be inconvenient to use geckoargs with. This patch changes them to both be initialized during SandboxLaunch::Configure in the parent process, and then be passed down to the process launching code either within the LaunchOptions object, or in the ChildProcessArgs object. Unfortunately, we need to read the command line arguments within XRE_InitChildProcess, rather than SandboxEarlyInit, as the sandbox code is not linked directly to libxul, where the file handle GeckoArgs methods are defined. One of the more significant functional changes here is that when using the fork server, the chroot pipe will be created within the parent process, with the server end of the pipe passed over IPC to the fork server to be used to create the chroot server. This is a bit unnecessary, but keeps things simpler for the fork server, as geckoargs are transferred directly from the parent process to the forked child processes over the forkserver exec pipe.
