Avi Kivity 19bf7c8708 Fix qapi code generation fix
The fixes to qapi code generation had multiple bugs:
- the Null class used to drop output was missing some methods
- in some scripts it was never instantiated, leading to a None return,
  which is missing even more methods
- the --source and --header options were swapped

Luckily, all those bugs were hidden by a makefile bug which caused the
old behaviour (with the race) to be invoked.

Avi Kivity 8d3bc5178f Fix qapi code generation wrt parallel build
Make's multiple output syntax

  x.c x.h: x.template
       gen < x.template

actually invokes the command once for x.c and once for x.h (with differing $@
in each invocation).  During a parallel build, the two commands may be invoked
in parallel; this opens up a race, where the second invocation trashes a file
supposedly produced during the first, and now in use by a dependent command.

The various qapi code generators are susceptible to this; fix by making them
generate just one file per invocation.

Luiz Capitulino 303b54b1a2 qapi: Automatically generate a _MAX value for enums
It's the last value in the enum and is very useful for the C
implementation.

Luiz Capitulino d2a80d6bb3 qapi: Don't use c_var() on enum strings
Otherwise if we have something like 'foo-bar' in the schema,
it will be generated as 'foo_bar' in the string lookup table.

c_var() is good for C variables, but not for enum strings.

Anthony Liguori 776574d641 qapi: add code generation support for middle mode
To get the ball rolling merging QAPI, this patch introduces a "middle mode" to
the code generator.  In middle mode, the code generator generates marshalling
functions that are compatible with the current QMP server.  We absolutely need
to replace the current QMP server in order to support proper asynchronous
commands but using a middle mode provides a middle-ground that lets us start
converting commands in tree.

Note that all of the commands have been converted already in my glib branch.
Middle mode only exists until we finish merging them from my branch into the
main tree.

Michael Roth fb3182ce6e qapi: add qapi-types.py code generator
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.
