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.
