196076 - add support for more DNS error codes

Status: NEW

(NSPR :: NSPR, defect)

Description

[benc]

As I understand it, NSPR only has only one error code right now (Bug 164715 #7)

Ideally, NSPR would add support for a couple more error codes:

> gethostbyname() has four error codes:
>
> #define HOST_NOT_FOUND  1 /* Authoritive Answer Host not found */
> #define TRY_AGAIN       2 /* Non-Authoritive Host not found, or
> SERVERFAIL */
> #define NO_RECOVERY     3 /* Non recoverable errors, FORMERR, REFUSED,
> NOTIMP */
> #define NO_DATA         4 /* Valid name, no data record of requested
> type */

This might need platform specific attention.

Right now, we can't do things like error saying that we could not contact the
DNS server. This is a distinct problem from requesting a hostname that is not in
DNS (for example, the root cause if often connectivity problems).
