. to a more generic name i.e. libxlDomainStartCallback,
since it will now cover another case other than the console.

Before pushing, I wanted to change the 'aop_console_how' variable to something
more generic too, but realized it is the 'const libxl_asyncprogress_how
*aop_console_how' parameter to libxl_domain_create_{new,restore}. AFAICT, this
callback is invoked when a console becomes available for the domain. It might be
possible that network devices have not been created (devid = -1) when the
callback is invoked. I thought about adding a separate libxlDomainStartCallback
and registering it with the 'const libxl_asyncop_how *ao_how' parameter, but
this would change the synchronous behavior of libxlDomainStart and be quite a
bit more intrusive.
In the end, I think it is best to explicitly call a function that creates the
ifnames after a successful libxl_domain_create_{new,restore}. See my reply to
2/2 for an example of this idea.
