qapi: untangle next_list

Right now, the semantics of next_list are complicated. The caller must:

  • call start_list
  • call next_list for each element including the first
  • on the first call to next_list, the second argument should point to
    NULL and the result is the head of the list. On subsequent calls,...

qapi: allow freeing partially-allocated objects

Objects going through the dealloc visitor can be only partially allocated.
Detect the situation and avoid a segfault. This also helps with the
input visitor, when there are errors.

qapi: shortcut visits on errors

We can exit very soon if we enter a visitor with a preexisting error.
This simplifies some cases because we will not have to deal with
obj being non-NULL while *obj is NULL.

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...

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...

qapi: modify visitor code generation for list iteration

Modify logic such that we never assign values to the list head argument
to progress through the list on subsequent iterations, instead rely only
on having our return value passed back in as an argument on the next...

qapi: add qapi-visit.py code generator

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...
