domiftune: Add API virDomain{S,G}etInterfaceParameters

The APIs are used to set/get domain's network interface's parameters.
Currently supported parameters are bandwidth settings.

* include/libvirt/libvirt.h.in: new API and parameters definition
* python/generator.py: skip the Python API generation
* src/driver.h: add new entry to the driver structure
* src/libvirt_public.syms: export symbols
