			Some of the generated qapi-types-MODULE.h are included all over the
place.  Changing a QAPI type can trigger massive recompiling.  Top
scorers recompile more than 1000 out of some 6600 objects (not
counting tests and objects that don't depend on qemu/osdep.h):
    6300 qapi/qapi-builtin-types.h
    5700 qapi/qapi-types-run-state.h
    3900 qapi/qapi-types-common.h
    3300 qapi/qapi-types-sockets.h
    3000 qapi/qapi-types-misc.h
    3000 qapi/qapi-types-crypto.h
    3000 qapi/qapi-types-job.h
    3000 qapi/qapi-types-block-core.h
    2800 qapi/qapi-types-block.h
    1300 qapi/qapi-types-net.h
Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.
This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h.  They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO().  Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles.  This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.
Improves things for some of the top scorers:
    3600 qapi/qapi-types-common.h
    2800 qapi/qapi-types-sockets.h
     900 qapi/qapi-types-misc.h
    2200 qapi/qapi-types-crypto.h
    2100 qapi/qapi-types-job.h
    2100 qapi/qapi-types-block-core.h
     270 qapi/qapi-types-block.h

| /**
 | |
|  * 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
