[PATCH 26/49] list: Expose virConnectListAllNetworks to Python binding

[Osier Yang <jyang@xxxxxxxxxx>]

The implementation is done manually as the generator does not support
wrapping lists of C pointers into Python objects.

python/libvirt-override-api.xml: Document

python/libvirt-override-virConnect.py: Implement listAllNetworks.

python/libvirt-override.c: Implementation for the wrapper.
