posix_spawn is less error-prone than vfork + exec, and can make use of system-specific optimizations like `clone' on Linux. Import Gnulib replacement so that we can use recent additions like `posix_spawn_file_actions_addchdir'. The only manual change are to admin/merge-gnulib and .gitignore. All other changes are due to rerunning merge-gnulib. * admin/merge-gnulib (GNULIB_MODULES): Add posix_spawn-related modules. * .gitignore: Add new generated files.
