Léo Lam 2f02cc2996 IOS/SSL: Make sure we are using a correct cert/key
This adds a check to the SSL code to make sure we are using the correct
client certificate and key (and root CA).

Now, instead of silently failing, the user will be notified whenever a
file is missing or when it is invalid, i.e. when the hash does not
match; this is likely to happen for existing users as the program
linked in the network guide extracted the wrong certs :(
