[PATCH liburing v2 0/8] Ensure we mark non-exported functions and variables as static

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

Hi Jens,

This is a v2 revision.

This series is a -Wmissing-prototypes enforcement. -Wmissing-prototypes
is a clang C compiler flag that warns us if we have functions or
variables that are not used outisde the translation unit, but not marked
as static.

There are 8 patches in this series:

- Patch #1, is just a typo cleanup.
- Patch #2, core library change, mark __io_uring_flush_sq() as static.
- Patch #3 to patch #7 are the cleanup preparation for
  -Wmissing-prototypes enforcement.
- Patch #8 is to enforce -Wmissing-prototypes on the GitHub CI robot.

This series has been build-tested each patch with the GitHub CI robot
and no breakage is found.

## Changelog

v2:
  - Add a new patch #1, fix typo.
  - Don't export __io_uring_flush_sq(). Instead, make a copy of this
    function in test/helpers.c.
  - Massage the commit message.
