Bug #705273 - Leaked sockets after failed authentication
Updated Galician translations
Bug 705206 - Stale "Retrieving message xxx" in preview panel

A client application cancelling an operation should not terminate the
parser thread.  The parser thread completes the operation even if the
client is no longer interested in the result.  The parser thread loop
must only be broken out of on an I/O error, parsing error, the server
hanging up, or application shutdown.
Bug 704885 - "Unknown background operation" when syncing spamassassin

The "spamassassin" Evolution module makes use of CamelJunkFilter's
synchronize() method, during which time we didn't have a status message
pushed on the CamelOperation (other than the default "Unknown background
operation", which users should never see).  This commit pushes a message.
Bug 704871 - Fails to manage subscription on an NNTP account
Updated Traditional Chinese translation(Hong Kong and Taiwan)
Add camel_imapx_parse_mailbox().

Parses a "mailbox" token, with the special case for "INBOX".
Add CamelIMAPXListResponse.

Represents an IMAP LIST response, including LIST-EXTENDED information.

Replaces the "list_info" struct and associated functions.

New functions:

  camel_imapx_list_response_new()
  camel_imapx_list_response_hash()
  camel_imapx_list_response_equal()
  camel_imapx_list_response_compare()
  camel_imapx_list_response_get_mailbox()
  camel_imapx_list_response_get_separator()
  camel_imapx_list_response_add_flag()
  camel_imapx_list_response_has_flag()
  camel_imapx_list_response_get_childinfo()
  camel_imapx_list_response_get_summary_flags()

Removed functions:

  imapx_parse_list()
  imapx_list_get_path()
  imapx_free_list()
CamelIMAPXStore: Remove NOINFERIORS -> NOCHILDREN hack.

CamelFolderListResponse already takes care of adding the implicit
/HasNoChildren attribute when /NoInferiors is seen.
Bug 705493 - Wrong default in configure help for --enable-largefile
CamelDiscoStore: Fix CamelServiceConnectionStatus tracking.

Do not set CAMEL_DISCO_STORE_OFFLINE when the CamelService reports
something other than CAMEL_SERVICE_CONNECTED.  That would lock the
store into offline mode such that further connection attempts will
simply invoke connect_offline() and never actually establish a new
server connection.
Add camel_imapx_mailbox_is_inbox().

Returns whether a mailbox name is the special mailbox INBOX.  The
function just performs a case-insensitive string comparison; it's
more for readability.

Missing mutex initialization in EDataBook/CalFactory
Bug #705444 - Can not create contact lists in LDAP address book
CamelIMAPXStore: Folder rename refactoring.

Break some logic out so it can be reused for unsolicited LIST responses.
CamelIMAPXListResponse: Parse extended items.

Parse extended items in LIST responses.  The extended item grammer is
rather open-ended, so rather than try to parse all possible extended
items, just parse the items with tags we understand and try to skip
the rest.  Currently those tags are CHILDINFO and OLDNAME.
Add camel_imapx_list_response_ref_extended_item().

Returns the extended item value for the given tag as a GVariant.
The type of the GVariant depends on the extended item.  If no value
for the given tag exists, the function returns NULL.
imapx_update_store_summary() cleanups.
