This also fixes the Unix part of bug 678369, and fixes bug 147659 as a convenient side-effect of using LaunchApp (which has the desired fd-closing behavior already) rather than directly using fork/exec. The main goal is to work around bug 227246, where PR_CreateProcess on Unix interferes with anything else that tries to use child processes. This does not fix that bug -- NSPR will still cause problems if used in that way -- but it's an adequate workaround for that bug in Gecko in almost all cases (the one known exception is nsAuthSambaNTLM, which uses NSPR directly and needs to be fixed separately). Waiting for the child process uses waitpid() directly, sharing the existing code used for OS X.
