940 *  for a complete explanation.
941 *
942 *  This extension already exists in some browsers (namely, Firefox 3), but
943 *  we provide it to support those that don't.
944 *
945 *  Parameters:
946 *    (Object) obj - The object that will become 'this' in the bound function.
947 *    (Object) argN - An option argument that will be prepended to the
948 *      arguments given for the function call

2611 *  XML DOM builder.
2612 *
2613 *  This object provides an interface similar to JQuery but for building
2614 *  DOM elements easily and rapidly.  All the functions except for toString()
2615 *  and tree() return the object, so calls can be chained.  Here's an
2616 *  example using the $iq() builder helper.
2617 *  > $iq({to: 'you', from: 'me', type: 'get', id: '1'})
2618 *  >     .c('query', {xmlns: 'strophe:example'})
2619 *  >     .c('example')
2620 *  >     .toString()
2621 *
2622 *  The above generates this XML fragment
2623 *  > <iq to='you' from='me' type='get' id='1'>
2624 *  >   <query xmlns='strophe:example'>
2625 *  >     <example/>
2626 *  >   </query>
2627 *  > </iq>
2628 *  The corresponding DOM manipulations to get a similar fragment would be
2629 *  a lot more tedious and probably involve several helper variables.
2630 *
2631 *  Since adding children makes new operations operate on the child, up()
2632 *  is provided to traverse up the tree.  To add two children, do
2633 *  > builder.c('child1', ...).up().c('child2', ...)
2634 *  The next operation on the Builder will be relative to the second child.

3109 *
3110 *  The *cookies* option allows you to pass in cookies to be added to the
3111 *  document. These cookies will then be included in the BOSH XMLHttpRequest
3112 *  or in the websocket connection.
3113 *
3114 *  The passed in value must be a map of cookie names and string values.
3115 *
3116 *  > { "myCookie": {
3117 *  >     "value": "1234",
3118 *  >     "domain": ".example.org",
3119 *  >     "path": "/",
3120 *  >     "expires": expirationDate
3121 *  >     }
3122 *  > }
3123 *
3124 *  Note that cookies can't be set in this way for other domains (i.e. cross-domain).
3125 *  Those cookies need to be set under those domains, for example they can be
3126 *  set server-side by making a XHR call to that domain to ask it to set any
3127 *  necessary cookies.
3128 *
3129 *  mechanisms:
3130 *
3131 *  The *mechanisms* option allows you to specify the SASL mechanisms that this
3132 *  instance of Strophe.Connection (and therefore your XMPP client) will
3133 *  support.
3134 *
3135 *  The value must be an array of objects with Strophe.SASLMechanism
3136 *  prototypes.
3137 *
3138 *  If nothing is specified, then the following mechanisms (and their
3139 *  priorities) are registered:
3140 *
3141 *      SCRAM-SHA1 - 70
3142 *      DIGEST-MD5 - 60
3143 *      PLAIN - 50
3144 *      OAUTH-BEARER - 40
3145 *      OAUTH-2 - 30
3146 *      ANONYMOUS - 20
3147 *      EXTERNAL - 10
3148 *
3149 *  WebSocket options:
3150 *  ------------------
3151 *
3152 *  If you want to connect to the current host with a WebSocket connection you
3153 *  can tell Strophe to use WebSockets through a "protocol" attribute in the
3154 *  optional options parameter. Valid values are "ws" for WebSocket and "wss"
3155 *  for Secure WebSocket.
3156 *  So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
3157 *
3158 *  > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
3159 *
3160 *  Note that relative URLs _NOT_ starting with a "/" will also include the path
3161 *  of the current site.
3162 *
3163 *  Also because downgrading security is not permitted by browsers, when using
3164 *  relative URLs both BOSH and WebSocket connections will use their secure
3165 *  variants if the current connection to the site is also secure (https).
3166 *
3167 *  BOSH options:
3168 *  -------------
3169 *
3170 *  By adding "sync" to the options, you can control if requests will
3171 *  be made synchronously or not. The default behaviour is asynchronous.
3172 *  If you want to make requests synchronous, make "sync" evaluate to true.
3173 *  > var conn = new Strophe.Connection("/http-bind/", {sync: true});
3174 *
3175 *  You can also toggle this on an already established connection.
3176 *  > conn.options.sync = true;
3177 *
3178 *  The *customHeaders* option can be used to provide custom HTTP headers to be
3179 *  included in the XMLHttpRequests made.
3180 *
3181 *  The *keepalive* option can be used to instruct Strophe to maintain the
3182 *  current BOSH session across interruptions such as webpage reloads.
3183 *
3184 *  It will do this by caching the sessions tokens in sessionStorage, and when
3185 *  "restore" is called it will check whether there are cached tokens with
3186 *  which it can resume an existing session.
3187 *
3188 *  The *withCredentials* option should receive a Boolean value and is used to
3189 *  indicate wether cookies should be included in ajax requests (by default
3190 *  they're not).
3191 *  Set this value to true if you are connecting to a BOSH service
3192 *  and for some reason need to send cookies to it.
3193 *  In order for this to work cross-domain, the server must also enable
3194 *  credentials by setting the Access-Control-Allow-Credentials response header
3195 *  to "true". For most usecases however this setting should be false (which
3196 *  is the default).
3197 *  Additionally, when using Access-Control-Allow-Credentials, the
3198 *  Access-Control-Allow-Origin header can't be set to the wildcard "*", but
3199 *  instead must be restricted to actual domains.
3200 *
3201 *  The *contentType* option can be set to change the default Content-Type
3202 *  of "text/xml; charset=utf-8", which can be useful to reduce the amount of
3203 *  CORS preflight requests that are sent to the server.
3204 *
3205 *  Parameters:
3206 *    (String) service - The BOSH or WebSocket service URL.
3207 *    (Object) options - A hash of configuration options
3208 *
3209 *  Returns:
3210 *    A new Strophe.Connection object.

3430     *    (Function) callback - The connect callback function.
3431     *    (Integer) wait - The optional HTTPBIND wait value.  This is the

3919     *  Add a stanza handler for the connection.
3920     *
3921     *  This function adds a stanza handler to the connection.  The
3922     *  handler callback will be called for any stanza that matches
3923     *  the parameters.  Note that if multiple parameters are supplied,
3924     *  they must all match for the handler to be invoked.
3925     *
3926     *  The handler will receive the stanza that triggered it as its argument.
3927     *  *The handler should return true if it is to be invoked again;
3928     *  returning false will remove the handler after it returns.*
3929     *
3930     *  As a convenience, the ns parameters applies to the top level element
3931     *  and also any of its immediate children.  This is primarily to make
3932     *  matching /iq/query elements easy.
3933     *
3934     *  Options
3935     *  ~~~~~~~
3936     *  With the options argument, you can specify boolean flags that affect how
3937     *  matches are being done.
3938     *
3939     *  Currently two flags exist:
3940     *
3941     *  - matchBareFromJid:
3942     *      When set to true, the from parameter and the
3943     *      from attribute on the stanza will be matched as bare JIDs instead
3944     *      of full JIDs. To use this, pass {matchBareFromJid: true} as the
3945     *      value of options. The default value for matchBareFromJid is false.
3946     *
3947     *  - ignoreNamespaceFragment:
3948     *      When set to true, a fragment specified on the stanza's namespace
3949     *      URL will be ignored when it's matched with the one configured for
3950     *      the handler.
3951     *
3952     *      This means that if you register like this:
3953     *      >   connection.addHandler(
3954     *      >       handler,
3955     *      >       'http://jabber.org/protocol/muc',
3956     *      >       null, null, null, null,
3957     *      >       {'ignoreNamespaceFragment': true}
3958     *      >   );
3959     *
3960     *      Then a stanza with XML namespace of
3961     *      'http://jabber.org/protocol/muc#user' will also be matched. If
3962     *      'ignoreNamespaceFragment' is false, then only stanzas with
3963     *      'http://jabber.org/protocol/muc' will be matched.
3964     *
3965     *  Deleting the handler
3966     *  ~~~~~~~~~~~~~~~~~~~~
3967     *  The return value should be saved if you wish to remove the handler
3968     *  with deleteHandler().
3969     *
3970     *  Parameters:
3971     *    (Function) handler - The user callback.
3972     *    (String) ns - The namespace to match.
3973     *    (String) name - The stanza name to match.

3977     *    (String) options - The handler options
3978     *
