Hi all,

could you please review this small patch which puts all tests for testlibrary classes into one location under /test/lib-test?

besides moving tests from test/jdk/lib/testlibrary and test/hotspot/jtreg/testlibrary_tests to test/lib-test the patch also
 - problem lists HexPrinterTest.java on windows due to JDK-8247521
 - introduces make targets to build native parts for the tests in test/lib-test (needed b/c one test has a native part)
 - adds randomness k/w to test/lib-test (as it's used by RandomGeneratorTest.java)
 - makes Test class used by TestNativeProcessBuilder a static nested class of TestNativeProcessBuilder
 - updates LingeredAppTest to use @build instead of @compile and adds necessary @library tag
 - removes AssertsTest.java, OutputAnalyzerTest.java from test/hotspot/jtreg/testlibrary_tests as they are either identical or lesser that the same tests from test/jdk/lib/testlibrary/
 - merges test/hotspot/jtreg/testlibrary_tests/OutputAnalyzerTest.java and  test/jdk/lib/testlibrary/OutputAnalyzerTest.java (effectively adds test cases for `firstMatch` to the superier copy from test/jdk/lib/testlibrary)

testing: test/lib-test on {windows,linux,macosx}-x64

Thanks,
