Re-arrange python generator to make it clear what's auto-generated
* README: New file describing what each file is used for * livvirt-override.c, libvirt-override.py, libvirt-override-api.xml, libvirt-override-virConnect.py: Manually written code overriding the generator * typewrappers.c, typewrappers.h: Data type wrappers * generator.py: Automatically pre-prend contents of libvirt-override.py to generated libvirt.py. Output into libvirt.py directly instead of libvirtclass.py. Don't generate libvirtclass.txt at all. Write C files into libvirt.c/.h directly * Makefile.am: Remove rule for creating libvirt.py from libvirt-override.py and libvirtclass.py, since generator.py does it directly
