[PATCH v3 5/6] pacat: Replace read(), write() with pa_* equivalent.

[kugel@xxxxxxxxxxx (Thomas Martitz)]

From: Thomas Martitz <kuge@xxxxxxxxxxx>

Calling pa_read() and pa_write() seems more appropriate since they deal better
with platform specific issues. This doesn't actually fix any open issue since
only stdio is affected but it seems more future proof.
