Rename sandbox_getaddrinfo() functions.
From my branch for legacy/trac#26524 (moved):
+// XXXX rename these. They are named as though they were sandbox-only, +// XXXX but in fact they're the only allowed entry point to getaddrinfo. +// XXXX They don't invoke the sandbox code; they only have an internal cache.
These functions should be called something like tor_getaddrinfo...(), or tor_getaddrinfo_cache...()
