Documentation: virtual: Convert paravirt_ops.txt to .rst
Convert paravirt_opts.txt to .rst format to be able to be parsed by sphinx. Made some minor spacing and formatting corrections to make defintions much more clear and easy to read. Added default kernel license to the document. Signed-off-by: Luke Nowakowski-Krijger <lnowakow@eng.ucsd.edu> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
