Fix GH-13727: macro generating invalid call test prototypes fixes.

autoconf/libtool generating code to test features missed `void` for
C calls prototypes w/o arguments.
Note that specific changes related to libtool have to be upstreamed.

*/*.m4: update main() signatures.

One warning that will soon become an error is -Wstrict-prototypes.
This is relatively easy to catch in most code (it will fail to
compile), but inside of autoconf tests it can go unnoticed because
many feature-test compilations fail by design. For example,

$ export CFLAGS="$CFLAGS -Werror=strict-prototypes"
$ ./configure
...
checking if iconv supports errno... no
configure: error: iconv does not support errno

(this is on a system where iconv *does* support errno). If errno
support were optional, that test would have "silently" disabled
it. The underlying issue here, from config.log, is

conftest.c:211:5: error: function declaration isn't a prototype
[-Werror=strict-prototypes]
211 | int main() {

This commit goes through all of our autoconf tests, replacing main()
with main(void). Up to equivalent types and variable renamings, that's
one of the two valid signatures, and satisfies the compiler (gcc-12 in
this case).

Fixes GH-10751

Remove PTHREADS_ASSIGN_VARS

This simplifies TSRM build steps a bit and avoids doing unnecessary
steps:
- The `PTHREADS_CHECK_COMPILE` can called inside the for loops only
since this is only where the `$pthreads_checked` variable is used.
- Assigning variables can be then done only in the configure.ac
once.
- use `m4_include()` instead of the `sinclude()` in the middle of
the build steps.
- The `$threads_result` variable is not used in the code or in
extensions.

Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns

- Macro definitions include similar pattern header comments now
