 /**
  * Sets mailbox metadata.
  *
  * Provides support for the IMAP METADATA extension; both the
  * final RFC version
  * (<a href="https://tools.ietf.org/html/rfc5464">RFC 5464</a>)
  * and the older, incompatible draft version (known as ANNOTATEMORE)
  * (<a
  * href="https://tools.ietf.org/html/draft-daboo-imap-annotatemore-07"
  * >draft-daboo-imap-annotatemore-07</a>).  See setServerCompatibility().
  *
  * Note that in Annotatemore mode, this job can only operate on
  * one metadata entry at once.
  *
  * This job can only be run when the session is in the
  * authenticated (or selected) state.
  *
  * If the server supports ACLs, the user will need the
  * Acl::Lookup right on the mailbox, as well as one of
  * - Acl::Read
  * - Acl::KeepSeen
  * - Acl::Write
  * - Acl::Insert
  * - Acl::Post
  * Otherwise, the user must be able to list the mailbox
  * and either read or write the message content.
  *
  * Note that even if the user has these permissions, the
  * server may refuse to allow the user to write metadata
  * based on some other criteria.
  *
  * Note also that on servers that implement the Annotatemore
  * version of the extension, only Acl::Lookup rights are
  * required (ie: the user must be able to list the mailbox).

      *
      * When in Metadata mode, this method adds a metadata
      * entry to the list of metadata additions and updates that
      * will be performed when the job is run.
      *
      * @p name must be a valid ASCII string and may not contain two
      * consecutive forward slashes ('/'), must not end with '/' and
      * must not contain '*', '%', non-ASCII characters or characters
      * in the ASCII range 0x00 to 0x19 (in practice, all control
      * characters should be avoided).  The name is case-insensitive.
      *
      * The first part of the entry name should be "/private" or
      * "/shared", indicating the scope of the entry.  Note that
      * private metadata may not be supported by all servers.
      *
      * Server metadata entry names include:
      * - /shared/comment
      * - /shared/admin - a URI for contacting the server administrator
      *                   (eg: a mailto: or tel: URI)
      * - /shared/vendor/<vendor-token>/something
      * - /private/vendor/<vendor-token>/something
      *
      * Mailbox metadata entry names include:
      * - /shared/comment
      * - /private/comment
      * - /shared/vendor/<vendor-token>/something
      * - /private/vendor/<vendor-token>/something
      *
      * @p value can be any data, although if it is a multi-line string
      * value, CRLF line-endings must be used.
      *
      * In Annotatemore mode it is possible to prefix the entry name with a /shared or /private prefix, that is automatically translated
      * to an appropriate value.shared|priv attribute.
      *
      * Annotatemore legacy mode:
      * When in Annotatemore mode, this method adds an attribute
      * entry to the list of additions and updates that will be
      * performed on the metadata entry when the job is run.
      *
      * @p name must be a valid UTF-8 string, and may not contain the
      * '%' or '*' characters, or NUL.  Use of non-visible UTF-8 characters
      * is strongly discouraged.
      *
      * Possible attribute name prefixes are:
      * - value - the data value of the attribute
      * - content-type - a MIME content type and subtype
      * - content-language - a RFC 3282 language code
      * - vendor.<vendor-token> - a vendor-specific attribute
      *
      * Attribute names an attribute name prefix followed by ".priv" for
      * private attributes or ".shared" for shared attributes.  Note that
      * the attributes "size.priv" and "size.shared" are read-only
      * attributes set by the server, and so cannot be used with
      * SetMetaDataJob.

      * @param name   the metadata entry name (Metadata or Annotatemore mode) in ASCII or
      *               attribute name (Annotatemore mode, if used without /shared or /private prefix) in UTF-8
