usage: allow pluggable die-recursion checks
When any git code calls die or die_errno, we use a counter to detect recursion into the die functions from any of the helper functions. However, such a simple counter is not good enough for threaded programs, which may call die from a sub-thread, killing only the sub-thread (but incrementing the counter for everyone). Rather than try to deal with threads ourselves here, let's just allow callers to plug in their own recursion-detection function. This is similar to how we handle the die routine (the caller plugs in a die routine which may kill only the sub-thread).
