[libvirt] PATCH: Fix many many win32 bugs

Latest GCC changed the meaning of 'printf' attribute annotation to refer
to the host platform's native format specifiers. On Win32/mingw32 this
means it is now validating against Microsoft's useless format specifiers.
We replace all the printf like functions on Win32 thanks to GNULIB and
thus should always validate against the GNU format specifiers.
This means we have to use the 'gnu_printf' annotation everywhere, but
only for GCC >= 4.4.
This also disables the 'pwd' and 'cd' commands in virsh because neither
of those build successfully on Win32.
Finally, disables the OpenNebula driver on Win32

the one for virAsprintf, in util.h:

+ ATTRIBUTE_FMT_PRINTF(2, 3);
This makes it so gcc's -Wformat and -Wformat-security options can do
their jobs and cross-check format strings with the number and types
