[PATCH v2] core-util: Make pa_make_secure_dir() act like mkdir -p

[arun.raghavan@xxxxxxxxxxxxxxx (Arun Raghavan)]

(Sorry, that was the wrong patch. This is the correct v2, amended for working
with win32).

This makes pa_make_secure_dir() create any missing parent directories in
the given path as well. This is useful, for example, on a pristine
system with a clean $HOME that needs ~/.config/pulse/ to be created when
~/.config does not exist.
