rra-c-util 8.0

This is a roll-up of a lot of changes to my utility package for C (and increasingly for Perl). It's been more than a year since the last release, so it's long-overdue.

Most of the changes in this release are to the Perl test libraries and accompanying tests. Test::RRA now must be imported before Test::More so that it can handle the absence of Test::More (such as on Red Hat systems with perl but not perl-core installed). The is_file_contents function in Test::RRA now handles Windows and other systems without a diff program. And there are more minor improvements to the various tests written in Perl.

The Autoconf probe RRA_LIB_KRB5_OPTIONAL now correctly handles the case where Kerberos libraries are not available but libcom_err is, rather than incorrectly believing that Kerberos libraries were present.

As of this release, rra-c-util now tests the Perl test programs that it includes, which requires it to build and test a dummy Perl module. This means the build system now requires Perl 5.6.2 and the Module::Build module.

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