[PATCH] compat/mingw: stubs for getpgid() and tcgetpgrp()

Windows does not have process groups. It is, therefore, the simplest to pretend that each process is in its own process group.

While here, move the getppid() stub from its old location (between two sync related functions) next to the two new functions.
