Fold fastlib into vespalib and gc some unused code.

Also move some code only used by juniper up into juniper test module.

+ * Author: Bård Kvalheim
+ *
+ * The test class of the testsuite. Written by Chuck Allison.
+ * http://www.cuj.com/archive/1809/feature.html
+ *
+ * Apart for a trick the usage of the test class is very simple:
+ *
+ * mytest.h:
+ * ----
+ * #include <iosfwd>
+ * #include <vespa/fastlib/testsuite/test.h>
+ *
+ * class MyTest : public Test
+ * {
+ * public:
+ *   virtual void Run() {
+ *     // do the tests _test is ok if the argument are true
+ *     _test(expr);
+ *   }
+ *
+ * };
+ *
+ * class MyTestApp
+ * {
+ * public:
+ *   int Main();
+ * };
+ *
+ *
+ * ----
+ *
+ *
+ * mytest.cpp:
+ * ----
+ * #include "mytest.h"
+ *
+ * int MyTestApp::Main()
+ * {
+ *   MyTest mt;
+ *   mt.SetStream(&std::cout);
+ *   mt.Run();
+ *   mt.Report();
+ *
+ *   return 0;
+ * }
+ *
+ *
+ * ----
+ *
+ * The trick is that the all the code except the main function is in
+ * the .h file. The reason for this is that it is simpler to integerate
+ * the single test into a suite of tests.
