build: adapt qom/Makefile and move it to Makefile.objs

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.

build: move rules for nesting to Makefile.objs

At this point we will start adding nesting behavior to other files
than Makefile.target.  Because Makefile.objs is included by
Makefile.target, it is simpler to move the processing of
subdirectories there.

To enable this, only add per-target files to obj-y.  Use a separate
variable for the linker dependencies, all-obj-y.  This variable includes
obj-y and also all objects that are taken from other directories.

dump: remove dumping stuff from cpu-all.h

This simplifies things, because they will only be included for softmmu
targets and because the stubs are taken out-of-line in separate files,
which in the future could even be compiled only once.

This adds the 'magic' rules that take care of subdirectories.
The subdirectory makefiles in the source tree are not complete; they
only define some variables (listed in nested-vars) according to the
configuration.

The magic rules descend into subdirectory makefiles and gather the
evaluated values of those variables.  The values from all subdirectories
are joined together, each prefixed with the subdirectory name, and used
by the "real" makefiles.

Kill off cpu_state_reset()

In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.

All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

Add 'query-events' command to QMP to query async events

Sometimes it is neccessary for an application to determine

qapi: convert netdev_add

This is not a full QAPI conversion, but an intermediate step.

In essence, do_netdev_add() is split into three functions:

 1. netdev_add(): performs the actual work. This function is fully
    converted to Error (thus, it's "qapi-friendly")

 2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is
    coded by hand and not auto-generated (gen=no in the schema). The
    reason for this it's a lot easier and simpler to with QemuOpts
    this way

 3. hmp_netdev_add(): HMP front-end.

This design was suggested by Paolo Bonzini.
