Subject: stun: Use dynamic array instead of stack allocated array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dynamic on-stack arrays are not supported in Visual Studio.

This has the downside of introducing an extra memory allocation into
libstun, but it’s on a debug path so should be harmless.
