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.

Remove obsolescent AC_C_INLINE Autoconf macro (#13429)

This macro defines the inline keyword to be `__inline__`, `__inline`,
or empty, based on the compiler inline support. Since PHP requires C99,
which has the inline keyword definition and all current compilers
support it, this check is redundant and not needed anymore.

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

The next generation of C compilers is going to enforce the C standard
more strictly:

https://wiki.gentoo.org/wiki/Modern_C_porting

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).
