rra-c-util 3.6

Both of the fixes in this release are minor, but releases are cheap, so I may as well put a version number on it. Error handling in network_accept_any now handles the (usually impossible) case of select returning without an error but without adding anything to the fd sets. And pam_getenvlist in the fakepam testing library now returns an empty environment rather than NULL if no environment variables have been set.

You can get the latest version from the rra-c-util distribution page.
