build: remove universal-obj-y

All of universal-obj-y, user-obj-y (right now unused) and common-obj-y can
be unified into common-obj-y if we take care of defining CONFIG_SOFTMMU
and CONFIG_USER_ONLY in the toplevel makefile. This is similar to how
we define symbols for hardware components.

build: consolidate multiple variables into universal-obj-y

The directory descent mechanism, and a less-flat tree both helped
in making some *-obj-y definitions very short. Many of these
often end up in universal-obj-y, and used to be separate only
because of libuser (which is now part of history...).

Consolidate these variables in a single one.

Make all static TypeInfos const

Make all static TypeInfos const

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.

Fix the documented QOM examples:

sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h

Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:

sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c

This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

qom: make object_delete usable for statically-allocated objects

Store in the object the freeing function that will be used at deletion
time. This makes it possible to use object_delete on statically-allocated
(embedded) objects. Dually, it makes it possible to use object_unparent
and object_unref without leaking memory, when the lifetime of object
might extend until after the call to object_delete.

qom: fix refcount of non-heap-allocated objects

The reference count for embedded objects is always one too low, because
object_initialize_with_type returns with zero references to the object.
This causes premature finalization of the object (or an assertion failure)
after calling object_ref to add an extra reference and object_unref to
remove it.

The fix is to move the initial object_ref call from object_new_with_type
to object_initialize_with_type.
