testsuite: Prepare for -std=gnu23 default

Browse Source 
Now that C23 support is essentially feature-complete, I'd like to
switch the default language version for C compilation to -std=gnu23.

This requires updating a large number of testcases that fail with the
new language version if left unchanged.  In this patch, update most of
the tests for which there is a safe change that works both before and
after the update to default language version - typically adding the
option -std=gnu17 or -Wno-old-style-definition to the tests.  (There
are also a few tests where I'd like to investigate further why they
fail with -std=gnu23, or where I think such failures show an actual
bug to fix before changing the default language version, or where it
seems more appropriate to make a testcase change that would result in
failures in the absence of the language version change rather than
just adding an option that does nothing with the gnu17 default.)

The libffi test fixes have also been submitted upstream:
<https://github.com/libffi/libffi/pull/861>.

Most of the failures requiring such changes are for one of two
reasons:

* Unprototyped function declarations with () (meaning the same as
  (void) in C23 mode) for a function then called with arguments.

* Old-style function definitions, which warn by default in C23 mode,
  so resulting in test failures for the unexpected warnings.

Other reasons for failures include:

* Tests with their own definitions of bool, true and false.

* Tests of diagnostics (often with -pedantic) in cases where C23 has
  changed semantics, such as:

  - tag compatibility for structs;
  - enum values out of range of int;
  - handing of qualified array types;
  - decimal floating types formerly needing -pedantic diagnostics, but
    being standard in C23.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.
