Brooks Davis b0d29bc47d Import the kyua test framework.
Having kyua in the base system will simplify automated testing in CI and
eliminates bootstrapping issues on new platforms.

The build of kyua is controlled by WITH(OUT)_TESTS_SUPPORT.

/// \file store/layout.hpp
/// File system layout definition for the Kyua data files.
///
/// Tests results files are all stored in a centralized directory by default.
/// In the general case, we do not want the user to have to worry about files:
/// we expose an identifier-based interface where each tests results file has a
/// unique identifier. However, we also want to give full freedom to the user
/// to store such files wherever he likes so we have to deal with paths as well.
///
/// When creating a new results file, the inputs to resolve the path can be:
/// - NEW: Automatic generation of a new results file, so we want to return its
/// public identifier and the path for internal consumption.
/// - A path: The user provided the specific location where he wants the file
/// stored, so we just obey that. There is no public identifier in this case
/// because there is no naming scheme imposed on the generated files.
///
/// When opening an existing results file, the inputs to resolve the path can
/// be:
/// - LATEST: Given the current directory, we derive the corresponding test
/// suite name and find the latest timestamped file in the centralized
/// location.
/// - A path: If the file exists, we just open that. If it doesn't exist or if
/// it is a directory, we try to resolve that as a test suite name and locate
/// the latest matching timestamped file.
/// - Everything else: Treated as a test suite identifier, so we try to locate
/// the latest matchin timestamped file.
