Based on gnutls_record_send/recv man pages, we should use the return value of the functions as indicator what happened in the function and do not look into errno at all. Checking the errno value caused infinity loop in cupsd on busy servers if there were enough connection errors when cupsd wrote the response. The patch is provided by Paul Zirnik from SUSE - thank you for the patch! Fixes OpenPrinting#827

i see there is error - Looking into it. |
Per GNUTLS manual, `gnutls_record_recv()` can get GNUTLS_E_REHANDSHAKE and if it is HTTP client, we should not close the connection and ignore the error. The server can terminate the connection as before.

(follows #1507 )
During the review of #1507 I was told there is gnutls error which would be great to handle it separately - GNUTLS_E_REHANDSHAKE - when receiving data.
There are several ways how to handle this based on which side the HTTP library is used on:
The MR ignores the error on client side and terminates connection on server side.
