Enable running the daemon under valgrind.
This commit allows you to run the daemon under valgrind. You have to
enable it at configure time:
./configure --enable-valgrind-daemon
This should *not* be done for production builds.
When this feature is enabled, valgrind is added to the appliance and
the daemon is run under valgrind. Log messages from valgrind are
passed back over a virtio-serial channel into a file called
'valgrind.log.$PID' in the top build directory.
Running 'make check', 'make extra-tests' etc causes many
valgrind.log.* files to be created which must be examined by hand.
