Update to rra-c-util 4.8 and C TAP Harness 1.12

Update to rra-c-util 4.8:

* Look for krb5-config in /usr/kerberos/bin after the user's PATH.
* Kerberos library probing fixes without transitive shared libraries.
* Fix Autoconf warnings when probing for AIX's bundled Kerberos.
* Avoid using krb5-config if --with-{krb5,gssapi}-{include,lib} given.
* Correctly remove -I/usr/include from Kerberos and GSS-API flags.
* Build on systems where krb5/krb5.h exists but krb5.h does not.
* Pass --deps to krb5-config unless --enable-reduced-depends was used.
* Do not use krb5-config results unless gssapi is supported.
* Fix probing for Heimdal's libroken to work with older versions.
* Update warning flags for GCC 4.6.1.
* Update utility library and test suite for newer GCC warnings.
* Fix broken GCC attribute markers causing compilation problems.
* Suppress warnings on compilers that support gcc's __attribute__.
* Add notices to all files copied over from rra-c-util.
* Fix warnings when reporting memory allocation failure in messages.c.
* Fix message utility library compiler warnings on 64-bit systems.
* Include strings.h for additional POSIX functions where found.
* Use an atexit handler to clean up after Kerberos tests.
* Kerberos test configuration now goes in tests/config.
* The principal of the test keytab is determined automatically.
* Simplify the test suite calls for Kerberos and remctl tests.
* Check for a missing ssize_t.
* Improve the xstrndup utility function.
* Checked asprintf variants are now void functions and cannot fail.
* Fix use of long long in portable/mkstemp.c.
* Fix test suite portability to Solaris.
* Substantial improvements to the POD syntax and spelling checks.

Update to C TAP Harness 1.12:

* Fix compliation of runtests with more aggressive warnings.
* Add a more complete usage message and a -h command-line flag.
* Flush stderr before printing output from tests.
* Better handle running shell tests without BUILD and SOURCE set.
* Fix runtests to honor -s even if BUILD and -b aren't given.
* runtests now frees all allocated resources on exit.
* Only use feature-test macros when requested or built with gcc -ansi.
* Drop is_double from the C TAP library to avoid requiring -lm.
* Avoid using local in the shell libtap.sh library.
* Suppress warnings on compilers that support gcc's __attribute__.
