[Qemu-devel] [PATCH 55/56] json: Clean up headers

[Markus Armbruster <armbru@redhat.com>]

The JSON parser has three public headers, json-lexer.h, json-parser.h,
json-streamer.h.  They all contain stuff that is of no interest
outside qobject/json-*.c.

Collect the public interface in include/qapi/qmp/json-parser.h, and
everything else in qobject/json-parser-int.h.
