Markus Armbruster 2ae16a6aa4 Include generated QAPI headers less
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
