[PATCH v3] Cygwin: Add spawn family of functions to docs

[Mark Geisert]

In the doc tree, add a new section "Other system interfaces[...]" that
lists the spawn family of functions, most of the exposed cygwin internal
functions that a user might have use for, and some other functions
duplicating Windows or DOS interfaces that might have some utility.
