Import posix_spawn from Gnulib.
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.
