Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer. The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert. Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer". It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().
The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

Since commit 83ee768d6247b, we now have two places that define the
QJSON type:
$ git grep 'typedef struct QJSON QJSON'
include/migration/vmstate.h:typedef struct QJSON QJSON;
migration/qjson.h:typedef struct QJSON QJSON;
This breaks docker-test-build@centos6:
In file included from /tmp/qemu-test/src/migration/savevm.c:59:
/tmp/qemu-test/src/migration/qjson.h:16: error: redefinition of typedef
'QJSON'
/tmp/qemu-test/src/include/migration/vmstate.h:30: note: previous
declaration of 'QJSON' was here
make: *** [migration/savevm.o] Error 1
This happens because CentOS 6 has an old GCC 4.4.7. Even if redefining
a typedef with the same type is permitted since GCC 4.6, unless -pedantic
is passed, we don't really need to do that on purpose. Let's have a
single definition in <qemu/typedefs.h> instead.
