[libvirt] [PATCH v2 3/3] tests: Add test program for APIs which changes domain conf on the fly



The test driver free()s the test domain conf each time when
the connection is closed, so it's not able to test the APIs
which change the domain conf on the fly with virsh.

This patch is to add a new test program domapitest.c, which
tests the APIs by directly invoking the C APIs. Currently there
is only one test in it for setNumaParameters testing, but similiar
APIs testing can be added there.
