Comment (by nickm):

 QUick review:
   * In prot_strings, you say: "strlen((char*) el->param)".  Why the cast?
 If we don't know it's a char*, we shouldn't be taking strlen() of it.
 (Are some of these an intptr? The type seems to be an intptr_t ... how do
 we know which ones are strings?)
   * In prot_strings, string lengths should really be size_t.
   * Use tor_malloc() and tor_free() instead of malloc and free.
   * Use tor_strdup(), not strdup().
   * Every function should have documentation.
   * The hints argument to getaddrinfo is "const struct addrinfo hints *",
 not "struct addrinfo hints".  Shouldn't sandbox_getaddrinfo look the same
 way?
