Daniel P. Berrangé 90e33dfec6 util: add helper APIs for dealing with inotify in portable manner
The inotify userspace API for reading events is quite horrible, so it is
useful to wrap it in a more friendly API to avoid duplicating code
across many users in QEMU. Wrapping it also allows introduction of a
platform portability layer, so that we can add impls for non-Linux based
equivalents in future.
