Eduardo Habkost 30b5707c26 qom: Remove module_obj_name parameter from OBJECT_DECLARE* macros
One of the goals of having less boilerplate on QOM declarations
is to avoid human error.  Requiring an extra argument that is
never used is an opportunity for mistakes.

Remove the unused argument from OBJECT_DECLARE_TYPE and
OBJECT_DECLARE_SIMPLE_TYPE.

Coccinelle patch used to convert all users of the macros:

  @@
  declarer name OBJECT_DECLARE_TYPE;
  identifier InstanceType, ClassType, lowercase, UPPERCASE;
  @@
   OBJECT_DECLARE_TYPE(InstanceType, ClassType,
  -                    lowercase,
                       UPPERCASE);

  @@
  declarer name OBJECT_DECLARE_SIMPLE_TYPE;
  identifier InstanceType, lowercase, UPPERCASE;
  @@
   OBJECT_DECLARE_SIMPLE_TYPE(InstanceType,
  -                    lowercase,
                       UPPERCASE);

Eduardo Habkost db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Paolo Bonzini b58deb344d qemu/queue.h: leave head structs anonymous unless necessary
Most list head structs need not be given a name.  In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed.  In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct.  So clean up everything, not giving a
name except in the rare case where it is necessary.

Ladi Prosek 60253ed1e6 rng: add request queue support to rng-random
Requests are now created in the RngBackend parent class and the
code path is shared by both rng-egd and rng-random.

This commit fixes the rng-random implementation which processed
only one request at a time and simply discarded all but the most
recent one. In the guest this manifested as delayed completion
of reads from virtio-rng, i.e. a read was completed only after
another read was issued.

By switching rng-random to use the same request queue as rng-egd,
the unsafe stack-based allocation of the entropy buffer is
eliminated and replaced with g_malloc.

which it implies are not included manually.

This commit was created with scripts/clean-includes.

NB: If this commit breaks compilation for your out-of-tree
patchseries or fork, then you need to make sure you add
#include "qemu/osdep.h" to any new .c files that you have.
