Add ssl:getstat/1 and ssl:getstat/2
These functions call getstat on the underlying TCP socket. The only way to do this before now was to use a hack, either by looking inside the #sslsocket{} record directly, or by not using the SSL listen/accept functions and upgrading from a TCP socket that is kept around for the purpose of calling getstat later on.
