ejabberd 15.10: HTTP upload, metrics and performance

This release includes a brand new module to help with file transfer. In XMPP transferring files between users required users to be online at the same time. It all changed with XEP-0363 and it is now possible to share file using HTTP protocol while doing the signaling over XMPP. Thanks to Holger and Evgeny, we are now pleases to include this feature in ejabberd core, with mod_http_upload.

ejabberd now also include a module to export metrics information about ejabberd behaviour to Grapherl, a tool that was developed during the Google Summer of Code by Vanshdeep Singh. This is only the beginning, as we are planning to both increase the number of metrics and available backends in upcoming releases. As a start, you can now track the traffic (both from clients and between servers), the offline messages and the user registration and account deletion.

We improved the overall performance of ejabberd, thanks to optimisation in the XML parser.

We also improved the documentation to help you set up mod_xmlrpc with OAuth for those who were already using it prior to 15.09 release.

Finally, as usual, we fixed bugs and improved many features across the whole server.

Here is the full list of changes.
