/**
*
* As a GET request, this module answers to activitypub and zot6 item fetches and
* acts as a permalink for local content.
*
* Otherwise this is the POST destination for most all locally posted
* text stuff. This function handles status, wall-to-wall status,
* local comments, and remote coments that are posted on this site
* (as opposed to being delivered in a feed).
* Also processed here are posts and comments coming through the API.
* All of these become an "item" which is our basic unit of
* information.
* Posts that originate externally or do not fall into the above
* posting categories go through item_store() instead of this function.
