[PATCH 00/18] Make block-backend-io.h API more consistent

[Alberto Faria]

Adjust existing pairs of non-coroutine and coroutine functions to share
the same calling convention, and add non-coroutine/coroutine
counterparts where they don't exist.

Also make the non-coroutine versions generated_co_wrappers.

This series sits on top of "[PATCH v2 00/10] Implement bdrv_{pread,
pwrite, pwrite_sync, pwrite_zeroes}() using generated_co_wrapper":
