[PATCH 00/13] remove some types from typedefs.h

[PATCH 00/13] remove some types from typedefs.h

[Paolo Bonzini]

The main reason for typedefs.h to exist is to avoid the need for
"struct Foo;" forward declarations of types that are needed in function
prototypes.  It avoids the infamous "struct declared inside parameter list
will not be visible outside of this definition or declaration" warning.
Another less common use is when the struct is used as a pointer in
another struct (when the struct is embedded by value, the typedef is
obviously not enough).

This series is a first pass removing unnecessary typedefs.  In most
cases, the users are actually already including it.  In a few patches
towards the end, new includes are introduced but not in files that
already "rebuild the world" when changed.

Personally, I think that in many cases the uses are so limited
(often they only appear only in the few non-qdev boards that are
left) that they could use forward declarations of structs.  I did
that for patch 12 (tcg) because there are already a couple of
forward declataions in include/hw/core/cpu.h, but that's more as
food for thought than anything else.

[PATCH 01/13] fw_cfg: remove useless declarations from typedefs.h

[Paolo Bonzini]

Only FWCfgState is used as part of APIs such as acpi_ghes_add_fw_cfg.
Everything else need not be in typedefs.h.

[PATCH 07/13] lockable: remove QemuLockable from typedefs.h

[Paolo Bonzini]

Using QemuLockable almost always requires going through QEMU_MAKE_LOCKABLE().
Therefore, there is little point in having the typedef always present.  Move
it to lockable.h, with only a small adjustment to coroutine.h (which has
a tricky co-dependency with lockable.h due to defining CoMutex *and*
using QemuLockable as a part of the CoQueue API).

[PATCH 09/13] monitor: remove MonitorDef from typedefs.h

[Paolo Bonzini]

MonitorDef is defined by hmp-target.h, and all users except one already
include it; the reason why the stubs do not include it, is because
hmp-target.h currently can only be used in files that are compiled
per target.  However, that is easily fixed.  Because the benefit of
having MonitorDef in typedefs.h is very small, do it and remove the
type from typedefs.h.

[PATCH 13/13] pci: remove some types from typedefs.h

[Paolo Bonzini]

For types that are embedded in structs defined by pci.h, the definition
is pretty much required to be available.  Remove them from typedefs.h.

I'd rather move from "hw/isa/i8259_internal.h" to here:

#define TYPE_PIC_COMMON "pic-common"
OBJECT_DECLARE_TYPE(PICCommonState, PICCommonClass, PIC_COMMON)

struct PICCommonState {
    ...
};

Can be done later, so meanwhile:
