dtc: Add valgrind support to testsuite This patch adds some options to the run_tests.sh script allowing it to run all the testcases under valgrind to check for pointer corruption bugs and memory leaks. Invoking "make checkm" will run the testsuite with valgrind. It include a mechanism for specifying valgrind errors to be suppressed on a per-testcase basis, and adds a couple of such suppression files for the mangle-layout and open_pack testcases which dump for use by other testcases a buffer which may contain uninitialized sections. We use suppressions rather than initializing the buffer so that valgrind will catch any internal access s to the uninitialized data, which would be a bug. The patch also fixes one genuine bug caught by valgrind - _packblocks() in fdt_rw.c was using memcpy() where it should have been using memmove(). At present the valgrinding won't do anything useful for testcases invoked via a shell script - which includes all the dtc testcases. I plan to fix that later.

dtc: Assorted improvements to test harness This patch makes several small improvements to the test harness. * An altered way of invoking shell script testcases from run_tests.sh means scripts no longer need to me marked executable in the repository to work properly. * dtc.sh never did anything that was really dtc specific - with the exception of messages, it would work equally well for any binary that returns 0 in the successful case. Therefore, generalise dtc.sh and fold it into run_tests.sh so we don't need a separate script any more. * Tweak various things so that the valgrind options are properly propagated down to invoke dtc under valgrind when called via wrapper scripts. * Tweak the valgrind suppressions to work properly on a wider range of systems (this was necessary on my machine running Ubuntu Hardy).
