[PATCH v3 00/26] block: fix coroutine_fn annotations

[Paolo Bonzini]

As discussed at KVM Forum 2022, I am reposting this series to
add more coroutine_fn annotations.  Fixing the annotations
enables static analysis of which functions are coroutine-only
and which are mixed (coroutine/non-coroutine).

A lot of the patches are similar to the ones that Marc-André Lureau
wrote back in 2017 (posted at [1]) but due to the changes in the code
it was easier to redo them.

This is a simple rebase of v2 (posted at [2]) with the following changes:
- patch 1 is new
- create_file_fallback_zero_first_sector is now marked as coroutine_fn
- blk_pwrite_zeroes is not a coroutine_fn anymore
- blk_pwrite is not a coroutine_fn anymore
- tracked_request_end is already a coroutine_fn in master
- some changes in commit messages
