Libvirt assumes that a SCSI bus can fit up to 8 devices
(including controller itself), except for so called wide bus
which can accommodate up to 16 devices (again, including
controller). This plays important role when computing 'drive'
address in virDomainDiskDefAssignAddress(). So far, the only
driver that enables wide SCSI bus is VMX. But with newer
releases, ESX is capable of "super wide" bus (64 devices).
We can blindly bump the limit in our code because then we would
compute address that's invalid for older ESX versions that we
still want to support.
Unfortunately, I haven't found a better place where to store this
than virDomainDef.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

Unfortunately g_date_time_new_from_iso8601 isn't available until
glib 2.56, and backporting it requires alot of code copying and
poking at private glib structs.
This reverts domain_conf.c back to its original parsing logic prior
to 810613a60efe3924c536b3663246900bc08910a5, but using g_date_time_new()
instead of gmtime(). The other files are then adapted to follow a
