Hi all!

The aim of the series is to reduce code-duplication and writing
parameters structure-packing by hand around coroutine function wrappers.

Benefits:
 - no code duplication
 - less indirection

v7: apply Eric's suggestions
02: fix grammar in commit msg, add Eric's r-b
04: - don't create separate header for generated_co_wrapper thing
    - inline aio_wait_kick() call
    - use json.dumps to make style for clang-format
05: - drop "#include "block/generated-co-wrapper.h" (since the header is removed)
    - add Eric's r-b

Vladimir Sementsov-Ogievskiy (7):
  block: return error-code from bdrv_invalidate_cache
  block/io: refactor coroutine wrappers
  block: declare some coroutine functions in block/coroutines.h
  scripts: add coroutine-wrapper.py
  block: generate coroutine-wrapper code
  block: drop bdrv_prwv
  block/io: refactor save/load vmstate
