[libvirt PATCH 05/10] conf: add new PCI_CONNECT flag AUTOASSIGN

[Laine Stump]

This new flag will be set for any controller that we decide can have
devices assigned to it automatically during PCI device assignment. In
the past PCI_CONNECT_TYPE_HOTPLUGGABLE was used for this purpose, but
that is overloading that flag, and no longer technically correct; what
we *really* want is to auto-assign devices to any pcie-root-port or
pcie-switch-downstream-port regardless of whether or not that
controller happens to have hotplug enabled.

This patch just adds the flag, but doesn't use it at all. Note that
the numbering of all the other flags was changed in order to insert
the new flag near the beginning of the list; that doesn't cause any
problem because the connect flags aren't stored anywhere between runs
of libvirtd.
