/**
* QAuthZListFile:
*
* This authorization driver provides a file mechanism
* for granting access by matching user names against a
* file of globs. Each match rule has an associated policy
* and a catch all policy applies if no rule matches
*
* To create an instance of this class via QMP:
*
* {
* "execute": "object-add",
* "arguments": {
* "qom-type": "authz-list-file",
* "id": "authz0",
* "props": {
* "filename": "/etc/qemu/myvm-vnc.acl",
* "refresh": true
* }
* }
* }
*
* If 'refresh' is 'yes', inotify is used to monitor for changes
* to the file and auto-reload the rules.
*
* The myvm-vnc.acl file should contain the parameters for
* the QAuthZList object in JSON format:
*
* {
* "rules": [
* { "match": "fred", "policy": "allow", "format": "exact" },
* { "match": "bob", "policy": "allow", "format": "exact" },
* { "match": "danb", "policy": "deny", "format": "exact" },
* { "match": "dan*", "policy": "allow", "format": "glob" }
* ],
* "policy": "deny"
* }
*
* The object can be created on the command line using
*
* -object authz-list-file,id=authz0,\
* filename=/etc/qemu/myvm-vnc.acl,refresh=yes
*
