[libvirt] [dbus PATCH v2 2/9] Abandon usage of all *TypeToString functions in connect.c

[Katerina Koukiou]

Converting ENUMS to str can be user friendly though
it can be problematic in matters of backward compatibility.

In particular when some ENUM in libvirt API will introduce a
new constant, libvirt-dbus will fail with:

size of array ‘_GStaticAssertCompileTimeAssertion_5’ is negative

So using ints is preferable to avoid the previous issue.
