This series add support for tag/keyword 'event' in qapi-schema. A new file was created to store some helper functions in patch 2, patch 4 is the test case, patch 5 is a convert example.
The implemention is done by generate API and a batch of parameters for each event define, it doesn't generate a struture and visit function in the background for every event, so it doesn't support nested structure in the define to avoid trouble. A callback layer is added to control the behavior. More detail can be found in patch 3's message and incode comments. v2: Address Luiz's comments: patch 3: rename *err to *local_err, do not initialize *qmp = NULL, create a new function qmp_build_evet_dict(). Other change: reorgnized script in patch 3, it have a clear three steps, see patch 3's incode comments. v3: Address Luiz's comments: 2/5: use -1 when fail to get host timestamp. 3/5: typo fix and better incode comments. all unchanged functions are moved into qmp-event.c, from generated file. To do so without include issue, 'int' was used intead of 'enum' in function prototype declaration, since the 'enum' define is a generated type. Address Eric's comments: 2/5: use -1 when fail to get host timestamp. 3/5: typo fix, add docs/qapi-code-gen.txt. 4/5: typo fix, verify no other fields in member 'timestamp'. 5/5: add doc in qapi-schema.json. fix license, all script using GPL2, all C code use LGPL, just as other similar files in upstream.
