Add basic support for CI test execution

Add basic support for executing continuous integration (CI) tests on
RHEL6, RHEL7, Fedora 20, Fedora Rawhide and Debian Testing.

This adds two front-end scripts which can be executed either locally by
developers, or on a CI server: contrib/ci/run and contrib/ci/clean.
The first one will run the tests and the second will wipe out the
artifacts.

See contrib/ci/README.md for further details.

+Usage: `basename "$0"` ERROR_EXITCODE [PATH_PATTERN...] [-- VALGRIND_ARG...]
+Run Valgrind, condensing logged reports into an exit code.
+
+Arguments:
+    ERROR_EXITCODE  An exit code to return if at least one error is found in
+                    Valgrind log files.
+    PATH_PATTERN    An extended glob pattern matching (original) paths to
+                    programs to execute under Valgrind. Execution is skipped
+                    and success is returned for non-matching programs. Without
+                    patterns, all programs match.
+    VALGRIND_ARG    An argument to pass to Valgrind after the arguments
+                    specified by `basename "$0"`.
+
+The first non-option VALGRIND_ARG will be considered the path to the program
+to execute under Valgrind and will be used in naming Valgrind log files as
+such:
+
+    PROGRAM_NAME.PID.valgrind.log
+
+where PROGRAM_NAME is the filename portion of the program path and PID is the
+executed process ID. If the last directory of the program path is ".libs" and
+the filename begins with "lt-", both are removed to match the name of libtool
+frontend script. All files matching PROGRAM_NAME.*.valgrind.log are removed
+before invoking Valgrind.
+
+If an error is found in Valgrind log files, ERROR_EXITCODE is returned,
+otherwise Valgrind exit code is returned.
