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.
