New subject: [PATCH 1/3] tests: Add controller-scsi-auto
The "auto" SCSI controller model was introduced for use in the
ESX driver, but the QEMU driver doesn't reject the value.
Add a test case showing the behavior when such a configuration
is encountered.

New subject: [PATCH 2/3] qemu: Handle MODEL_SCSI_{AUTO,DEFAULT} appropriately
The qemuDomainGetSCSIControllerModel() function, which is
responsible for choosing a model for a SCSI controller that
didn't have one provided by the user, considers values >0 to
mean "model has been set".
Since MODEL_SCSI_AUTO == 0, this means that such a value is
considered the same as MODEL_SCSI_DEFAULT (-1). This makes
sense, as not specifying a model name or explicitly asking for
one to be automatically chosen intuitively should result in
the same behavior.
Specifically, there is no case in which a value of
MODEL_SCSI_AUTO or MODEL_SCSI_DEFAULT is encountered after the
initial controller creation: it is either replaced with an
actual model, or an error is raised.
Despite this, there are a few places in the QEMU driver where
we incorrectly treat these values as if they were actual
model names. To reduce confusion, make sure that no longer
happens.
