bjorn3 386a63df42 pcid: Replace get_capabilities with get_vendor_capabilities 
While this stops returning raw MSI/MSI-X capabilities from
get_capabilities, the same info can be obtained using
fetch_all_features and feature_info.

bjorn3 588bbfe6a3 pcid: Stop returning feature enable status from fetch_all_features 
For the same reason the feature_status method was removed.

bjorn3 67d3015e2e Add helper for allocating a single MSI/MSI-X interrupt vector 
It doesn't actually configure the device to emit it though, but does
make this easier to do.

bjorn3 9b809312c2 Ignore MSI-X PBA in all drivers 
It isn't used in any driver and even on Linux no driver seems to use it
at all. The only times it seems to be useful are if you were to mask an
interrupt and want to check if the interrupt fired without unmasking or
if you want to make the device itself trigger an interrupt.

bjorn3 d0e90f5ded Remove fetch_header from pcid_interface 
Most things are already stored in SubdriverArguments and the couple of
things that aren't may change over time and thus should be read again
each time they are accessed, while fetch_header would receive a fixed
copy from pcid.

bjorn3 fcc55507ea Move the notify_multiplier field into a separate PciCapabilityNotify type 
It only exists for VIRTIO_PCI_CAP_NOTIFY_CFG and could conflict with
fields of other capability types.
