I line wrapped this and fixed a merge conflict in qemu_domain.c that got
introduced in the meantime.  Also, I shortened the subject line to fit
in 60 columns (for that matter, 'enum structure' doesn't make sense;
'enum type' or 'enum declaration' is closer to the C standard naming).

util: use typedefs for enums in "src/util/" directory

Most of your patch is mechanical changes of types that are now typedef'd...

...the remainder is the change to use typedefs.

It may have been cleaner to do one type per header file converted, but
the overall diffstat was still manageable for the types you converted.

Huh - that one was already a typedef, with the enum name used twice.

Once the conversions are all complete, I can help you write a syntax
check to ensure we use the same consistent style in new code.

ACK and pushed.  Congrats on your first libvirt patch.
