module_k/xcap_server: Added support HTTP 1.1 pre-conditions (If-Match: and If-None-Match:)

- Also fixed the ETag: header send by xcap_server as it should be a
  quoted-string (RFC 2616 section 3.11 and 14.19).
- If-Match (RFC 2616 section 14.24) and If-None-Match (RFC 2616
  section 14.26) are supported for the DELETE, GET, and PUT HTTP
  requests.

  This feature is useful as it enables clients to cache large XML
  documents (user-profiles/avatars/resource-lists) and only have to
  download them when they have actually changed (using If-None-Match:)

  If-Match: can help with the race conditions present when you have
  multiple simultaneous logins by helping to prevent clients from
  overwriting changes made by other clients.
