Add support to XMLRPC to handle enclosure from editPost/newPost - Patch for Wordpress 2.5 included

[amandato]

Attached code adds enclosure support to the XMLRPC functions. Enclosures are stored in wordpress in the postmeta table. Enclosure is a special struct within the content struct passed to the editPost/newPost functions. Adding this functionality will allow podcasters to post their media from another blogging application or service.

The code attached uses the styling of the attach_uploads() function and relies on the set_custom_fields() function. Through tests I've performed, the enclosure information is inserted correctly and displayed within the RSS 2.0 feed.

Please refer to Dave Winer's documentation for a reference how the enclosure struct is immpemented within the content struct of the addPost/editPost MetaWeblogAPI functions.

Attached patch was applied to the development version of Wordpress 2.5, last checked out revision 7524 from the Subversion repository.

Ticket #3405 was recently committed to -trunk [7847] to support enclosures for metaWeblog.newPost/editPost.

This includes a few updates to #6392 that fixes the test failures in that PR. See ​https://github.com/WordPress/wordpress-develop/pull/6392#discussion_r1622969056.

Note that commit ​76435fc cherry-picks the PR changes from #6696 so this should not be merged until that PR is approved.

The changes to ​https://github.com/WordPress/wordpress-develop/pull/6696 are now committed to trunk, so this should be good to merge.

The changes here have now been applied to the main PR in ​2083f0b, so am closing this as no longer necessary.
