VFIO allows multiple MSI-X vector, others doesn't, but maybe will
allow it in the future.
Device drivers need to be aware of the capability.
It's better to avoid condition check on interrupt type (VFIO) everywhere,
instead a capability api is more flexible for the condition change.

The patch exposes intr event fd create and release for PMD.
The device driver can assign the number of event associated with interrupt vector.
It also provides misc functions to check 1) allows other slowpath intr(e.g. lsc);
2) intr event on fastpath is enabled or not.

This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].
