This file doesn’t contain any real implementation, it just call the
`impl` functions from the platform-specific files
`gspawn-{posix,win32}.c`.
It serves as a location for the doc comments, introspection annotations
and API preconditions, and will be built on every platform. In
particular, this means that we get consistent GIR output for the
`g_spawn_*()` APIs regardless of whether GLib was built on Linux or
Windows.
