	win32ole: separate global variable declarations and definitions

	https://gcc.gnu.org/gcc-10/changes.html#c

	> * GCC now defaults to `-fno-common`.  As a result, global
	>   variable accesses are more efficient on various targets.  In
	>   C, global variables with multiple tentative definitions now
	>   result in linker errors.  With `-fcommon` such definitions are
	>   silently merged during linking.

	fix imemo entry description.

	* ext/objspace/objspace.c (count_imemo_objects): `imemo_type_ids`
	  should be match with `enum imemo_type` in internal.h and this
	  patch fix mismatch.

	Switch to download libffi source package to github releases from
	 sourceware.org


	Use osuosl instead of GitHub releases

	  Because the package provided by GitHub releases is different from sourceware.

	Guard static variable first

	* ext/openssl/ossl_asn1.c (Init_ossl_asn1): register the static
	  variable to grab an internal object, before creating the object.
	  otherwise the just-created object could get collected during the
	  global variable list allocation.  [Bug #16196]

	Slimed down test runtime by stressing openssl.so only [Bug #16196]


	Prefer rb_gc_register_mark_object

	* ext/openssl/ossl_asn1.c (Init_ossl_asn1): prefer
	  `rb_gc_register_mark_object`, which is better for constant
	  objects, over `rb_gc_register_address` for global/static
	  variables which can be re-assigned at runtime.  [Bug #16196]

	Skip very time consuming test [Bug #16196]
