[DCCP]: Convert Reset code into socket error number
This adds support for converting the 11 currently defined Reset codes into system error numbers, which are stored in sk_err for further interpretation. This makes the externally visible API behaviour similar to TCP, since a client connecting to a non-existing port will experience ECONNREFUSED. * Code 0, Unspecified, is interpreted as non-error (0); * Code 1, Closed (normal termination), also maps into 0; * Code 2, Aborted, maps into "Connection reset by peer" (ECONNRESET); * Code 3, No Connection and Code 7, Connection Refused, map into "Connection refused" (ECONNREFUSED); * Code 4, Packet Error, maps into "No message of desired type" (ENOMSG); * Code 5, Option Error, maps into "Illegal byte sequence" (EILSEQ); * Code 6, Mandatory Error, maps into "Operation not supported on transport endpoint" (EOPNOTSUPP); * Code 8, Bad Service Code, maps into "Invalid request code" (EBADRQC); * Code 9, Too Busy, maps into "Too many users" (EUSERS); * Code 10, Bad Init Cookie, maps into "Invalid request descriptor" (EBADR); * Code 11, Aggression Penalty, maps into "Quota exceeded" (EDQUOT) which makes sense in terms of using more than the `fair share' of bandwidth.
