rra-c-util 5.7

This release has a somewhat random collection of accumulated fixes.

A couple of them are for the PAM libraries: new support for the Mac OS X PAM implementation, which doesn't use the same options and error codes as the rest of the world. It also uses a different pattern of const declaration, which required some additional Autoconf probing for the fake PAM library for testing.

There are also a few fixes for the systemd probe framework: libsystemd-daemon has been rolled into libsystemd in current versions, and the probe was using $(), which doesn't work on Solaris 10.

The Kerberos Autoconf macros should now hopefully work with the version of Kerberos bundled with Solaris 10.

Finally, this release supports checking for Clang as a compiler and choosing compiler warning flags accordingly, although rra-c-util isn't warning-free with Clang -Weverything yet.
