From: Lev Stipakov <lev@openvpn.net>

With register_ring_buffers() being declared as "static" in header file,
all translation units, which include that header, got a copy of that function.
This causes GCC warning

  warning: "register_ring_buffers" defined but not used [-Wunused-function]

when compiling C files which include header, but don't use function.

Add "inline" keyword to silence this warning.

Thanks.  (Found while looking at the compiler warnings reviewing
the OpenSSL config loading patch).  Test built on MinGW, warnings gone.

Your patch has been applied to the master branch.
