This series adds VIR_ENUM_IMPL_LABEL and a demo conversion.
VIR_ENUM_IMPL_LABEL allows passing in a string that briefly describes the value the enum represents, which we use to generate error messages for FromString and ToString function failures.
This will allow us to drop a lot of code and unique strings that need translating.
Patch 2 is an example usage, converting virDomainVirtType enum. It's not a full conversion for this particular enum, just a demo. The enum creation now looks like
VIR_ENUM_IMPL_LABEL(virDomainVirt, "domain type", VIR_DOMAIN_VIRT_LAST, ...
FromString failure reports this error for value 'zzzz'
invalid argument: Unknown 'domain type' value 'zzzz'
ToString failure reports this error for unknown type=83
internal error: Unknown 'domain type' internal value '83'
Seems like a win to me but I'm interested in other opinions. This could also be a good BiteSizedTask for converting existing enums
Agreed.

I like this. You can count on my ACK. But we should probably let others chime in and express their preference. Michal
