[PATCH 1/4] libxl: populate build_info vfb in separate function

[PATCH 1/4] libxl: populate build_info vfb in separate function

[Jim Fehlig]

For HVM domains, vfb info must be populated in the libxl_domain_build_info
stuct.  Currently this is done in the libxlMakeVfbList function, but IMO
it would be cleaner to populate the build_info vfb in a separate
libxlMakeBuildInfoVfb function.  libxlMakeVfbList would then handle only
vfb devices, simiar to the other libxlMake<device>List functions.

A future patch will extend libxlMakeBuildInfoVfb to support SPICE.

Thanks.  I've fixed the typo in my local branch but will wait for
additional comments before posting a V2 (if necessary).

This seems really awkward to me. So you're using for() loop just to
check if the first graphics card (assuming there can't be more than one
anyway) is SPICE. If not, you could use 'continue' to continue with VNC.
I think this obfucates the code. Just move this into a separate function
and call it from here.

That's actually a bug, it should be def->graphics[i].  The idea is to prefer SPICE, but fall back to the first graphics device if no SPICE device is found. I mentioned this in the function comment. Perhaps that part of the comment should be moved to the for loop?

Thanks for the review and finding the bug in 3/4!  I changed it as we discussed 
and pushed the series.
