[libvirt] [PATCH] libxl config file convertion: correct `type=netfront' to 'type=vif'
According to current xl.cfg docs and xl codes, it uses type=vif
instead of type=netfront.
Currently after domxml-to-native, libvirt xml model=netfront will be
converted to xl type=netfront. This has no problem before, xen codes
for a long time just check type=ioemu, if not, set type to _VIF.
Since libxl uses parse_nic_config to avoid duplicate codes, it
compares 'type=vif' and 'type=ioemu' for valid parameters, others
are considered as invalid, thus we have problem with type=netfront
in xl config file.
#xl create sles12gm-hvm.orig
Parsing config from sles12gm-hvm.orig
Invalid parameter `type'.
Correct the convertion in libvirt, so that it matchs libxl codes
and also xl.cfg.

Since type=netfront config has been used for a very long time, at
lease for xm/xend, it has no problem. I'm not sure if we need to
split into xenParseXLVif vs xenParseXMVif, and xenFormatXLVif vs
xenFormatXMVif for this change?
