The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.
