This reverts commit efd641ffab.
This changeset seems to be needed to suppress a warning on Ubuntu 20.04

I guess there was a reason why the commit was reverted (maybe some CIs
failed?), so try it again.
* Use ffi_closure_free unconditionally.
The current conditionals reflect historic heritage of FFI. Usage of
ffi_closure_free should be better default nowadays, because libffi 3.0.5
fixing issues of ffi_closure_free should be widely available.
* RUBY_LIBFFI_MODVERSION is not used anymore.
Because `ffi_closure_free()` is not used unconditionally, there is no
other use for RUBY_LIBFFI_MODVERSION define, so drop its usage.
* Use more meaningful variable name.
`ver` variable used to be used to pupulate RUBY_LIBFFI_MODVERSION
define. Since the define was removed, the `libffi_dir` variable name
should better describe the remaining usage of the variable.

* ext/fiddle/extconf.rb: It supports to build libffi with standalone gem.

$(LIBFFI_DIR) instead of $(@D), since $(LIBFFI_A) is not
underneath libffi but under .libs.

Some external functions I wish to call may take a long time
and unnecessarily block other threads. This may lead to performance
regressions for fast functions as releasing/acquiring the GVL is not
cheap, but can improve performance for long-running functions
in multi-threaded applications.
This also means we must reacquire the GVL when calling Ruby-defined
callbacks for Fiddle::Closure, meaning we must detect whether the
current thread has the GVL by exporting ruby_thread_has_gvl_p
in internal.h
* ext/fiddle/function.c (struct nogvl_ffi_call_args):
new struct for GVL release
(nogvl_ffi_call): new function
(function_call): adjust for GVL release
[ruby-core:71642] [Feature #11607]
* ext/fiddle/closure.c (struct callback_args):
new struct for GVL acquire
(with_gvl_callback): adjusted original callback function
(callback): wrapper for conditional GVL acquire
* ext/fiddle/depend: add dependencies
* ext/fiddle/extconf.rb: include top_srcdir for internal.h
* internal.h (ruby_thread_has_gvl_p): expose for fiddle
* vm_core.h (ruby_thread_has_gvl_p): moved to internal.h
* test/fiddle/test_function.rb (test_nogvl_poll): new test

longer link extensions to ruby program with --enable-shared, the
