- Made the gnutls code path not even try to get the server cert if no peer 

verification is requested. Previously it would even return failure if gnutls
  failed to get the server cert even though no verification was asked for.

- Fix my Curl_timeleft() leftover mistake in the gnutls code

- Made the gnutls code path not even try to get the server cert if no peer
verification is requested. Previously it would even return failure if gnutls
failed to get the server cert even though no verification was asked for.
Public server showing the problem: https://www.net222.caisse-epargne.fr
- Fix my Curl_timeleft() leftover mistake in the gnutls code
- Pooyan McSporran found and fixed a flaw where you first would do a normal
http request and then you'd reuse the handle and replace the Accept: header,
as then libcurl would send two Accept: headers!
