This is the code generator for qapi command marshaling/dispatch.
Currently only generators for synchronous qapi/qmp functions are
supported. This script generates the following files:

  $(prefix)qmp-marshal.c: command marshal/dispatch functions for each
                          QMP command defined in the schema. Functions
                          generated by qapi-visit.py are used to
                          convert qobjects recieved from the wire into
                          function parameters, and uses the same
                          visiter functions to convert native C return
                          values to qobjects from transmission back
                          over the wire.

  $(prefix)qmp-commands.h: Function prototypes for the QMP commands
                           specified in the schema.

$(prefix) is used in the same manner as with qapi-types.py

This is the code generator for qapi visiter functions used to
marshal/unmarshal/dealloc qapi types. It generates the following 2
files:

  $(prefix)qapi-visit.c: visiter function for a particular c type, used
                         to automagically convert qobjects into the
                         corresponding C type and vice-versa, and well
                         as for deallocation memory for an existing C
                         type

  $(prefix)qapi-visit.h: declarations for previously mentioned visiter
                         functions

$(prefix) is used as decribed for qapi-types.py

This is the code generator for qapi types. It will generation the
following files:

  $(prefix)qapi-types.h - C types corresponding to types defined in
                          the schema you pass in
  $(prefix)qapi-types.c - Cleanup functions for the above C types

The $(prefix) is used to as a namespace to keep the generated code from
one schema/code-generation separated from others so code and be
generated from multiple schemas with clobbering previously created code.

Given an object recieved via QMP, this code uses the dispatch table
provided by qmp_registry.c to call the corresponding marshalling/dispatch
function and format return values/errors for delivery to the QMP.
Currently only synchronous QMP functions are supported, but this will
also be used for async QMP functions and QMP guest proxy dispatch as
well.

Type of Visiter class that serves as the inverse of the input visitor:
it takes a series of native C types and uses their values to construct a
corresponding QObject. The command marshaling/dispatcher functions will
use this to convert the output of QMP functions into a QObject that can
be sent over the wire.

Base definitions/includes for Visiter interface used by generated
visiter/marshalling code.

Includes a GenericList type. Our lists require an embedded element.
Since these types are generated, if you want to use them in a different
type of data structure, there's no easy way to add another embedded
element. The solution is to have non-embedded lists and that what this is.

GLib is an extremely common library that has a portable thread implementation
along with tons of other goodies.

GLib and GObject have a fantastic amount of infrastructure we can leverage in
QEMU including an object oriented programming infrastructure.

Short term, it has a very nice thread pool implementation that we could leverage
in something like virtio-9p.  It also has a test harness implementation that
this series will use.

Commit e4ea5e2d added the use of
the macro GCC_FMT_ATTR to error.h, however compiler.h is not
included by error.h

This will cause a build error when files including error.h
don't include qemu-common.h (or compiler.h). Not an issue today
because the only file including it is json-parser.h and it does
include qemu-common.h, but let's get it fixed.

This moves compiler related macros from qemu-common.h to compiler.h.

The reason for this change is that there are simple header files that
depend only on the compiler macros, so including qemu-common.h is overkill.

Besides, qemu-common.h is bloated and will benefit from some splitting.

Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to
not use double underscores as a prefix and the license text was added
by Vassili Karpov (malc), who is one of the authors of the new file.

Add QMP bits for snapshot_blkdev command. This is the same as
snapshot_blkdev in the human monitor. The command is synchronous.

In the future async commands and or a break down of the functionality
into multiple commands might be added.

Also change the 'snapshot_file' argument to 'snapshot-file' in
the human monitor, so that it matches QMP.

A host chardev could close just before the guest sends some data to be
written.  This will cause an -EPIPE error.  This shouldn't be propagated
to virtio-serial-bus.

Ideally we should close the port once -EPIPE is received, but since the
chardev interface doesn't return such meaningful values to its users,
all we get is -1 for any kind of error.  Just return 0 for now and wait
for chardevs to return better error messages to act better on the return
messages.
