[PATCH v3 0/8] Still more coroutine and various fixes in block layer

[Emanuele Giuseppe Esposito]

This is a dump of all minor coroutine-related fixes found while looking
around and testing various things in the QEMU block layer.

Patches aim to:
- add missing coroutine_fn annotation to the functions
- simplify to avoid the typical "if in coroutine: fn()
  // else create_coroutine(fn)" already present in generated_co_wraper
  functions.
- make sure that if a BlockDriver callback is defined as coroutine_fn, then
  it is always running in a coroutine.

This serie is based on Kevin Wolf's series "block: Simplify drain".

v2:
* clarified commit message in patches 2/3/6 on why we add coroutine_fn

Emanuele Giuseppe Esposito (8):
  block-copy: add missing coroutine_fn annotations
  nbd/server.c: add missing coroutine_fn annotations
  block-backend: replace bdrv_*_above with blk_*_above
  block: distinguish between bdrv_create running in coroutine and not
  block/vmdk: add missing coroutine_fn annotations
  block: bdrv_create_file is a coroutine_fn
  block: bdrv_create is never called in coroutine context
  block/dirty-bitmap: remove unnecessary qemu_in_coroutine() case
