Introduces USER_CREATABLE interface that must be implemented by
objects which are designed to created with -object CLI option or
object-add QMP command.
Interface provides an ability to do an optional second stage
initialization of the object created with -object/object-add
commands. By providing complete() callback, which is called
after the object properties were set.
It allows to:
* prevents misusing of -object/object-add by filtering out
objects that are not designed for it.
* generalize second stage backend initialization instead of
adding custom APIs to perform it
* early error detection of backend initialization at -object/
object-add time rather than through a proxy DEVICE object
that tries to use backend.

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.

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.

qom/ already used a separate makefile. Convert it to use relative
paths, and make it declare both common-obj-y and user-obj-y. This
way, the upper makefiles do not need to know that some QOM files
are compiled twice.
