[esan] Intercept calloc to avoid deadlocks with tcmalloc
Summary:
When tcmalloc initializes before esan, esan's initialization ends up
calling back into tcmalloc due to the calloc done by dlsym. This results
in a deadlock. We avoid this by special-casing this single allocation.
Intercepting calloc also gives us the opportunity to act on its zeroing as
stores by the application.
