[Meta] Convert configurable data to ConfigEntity system

Updated issue summary.

ECK makes entity types into configuration, which would make them ConfigEntity objects in 8.x. We'd need to sort out the dependencies between content and config entities to do that (a config entity can't be a config entity and there's no real need to dynamically define config entities either, or at least not as much), but it'd be cool to have the capability in core.

Updated issue summary.

Added #1799600: Add test of sorting for configuration entities

Added #1757566: Convert user account e-mail templates to configuration system

Updated issue summary.

Suppose we need to extend a list with
#916388: Convert menu links into entities
#1497380: Convert shortcut sets to ConfigEntity

@andypost just update the issue summary, and stop editing your comment :)

Removed #916388: Convert menu links into entities because menu links will be content entities, not config.

#2 injected into summary

Added menu conversion issue

Updated issue summary.

One remark :

Unless I'm very mistaken, the CMI files created by both the "convert image styles to ConfigEntities" & "convert contact categories to ConfigEntities" do not hold any uuid entry.

The CMI files created there bypass ConfigStorageController and use raw config() calls directly - which seems reasonable, but also skips uuid creation.
Similarly, it seems we skip the creation of the manifest files.

Since it seems that's a very easy mistake to make (we made it ourselves in #1852966: Rework entity display settings around EntityDisplay config entity so far), this kind of calls for a _config_update_create_structure() helper function of some kind ?

Menu links is realted

Why aren't date formats a ConfigEntity? Looking at admin/config/regional/date-time, it really looks like they should be.

That was #1571632: Convert regional settings to configuration system - did that go in before config entities?

That started way before ConfigEntity, but went in after. I think it was good that it went in as is, but it shouldn't be too hard to convert over now, and it fits the pattern perfectly.

Bumping this so it's independently critical from #1775842: [meta] Convert all variables to state and/or config systems. It'd be good to close the variables issue when we remove variable_*() but CMI's not really done until core configuration is either deployable (or explicitly marked as content/in limbo like path aliases might end up being).

Updated issue summary.

Would converting actions make sense? (I think it would, not signing up for it :). Currently these are very custom DB stored thingies. In fact they are stored with their params as serialised blobs. Pretty scary. A side effect for this for D8MI is you can set a dsm() to go to the user or set an email action with a subject and body, but never translate it ever in any way. If only actions would be config entities, we could get rid of one more one-off core db stored thingie and get translation support for freeeeee!

Actions seem like a simple thing with aid, type (node, user, etc), callback, parameters (blob, AKA arbitrary data structure) and label. Currently action module has such code as:

function action_load($aid) {
  return db_query("SELECT aid, type, callback, parameters, label FROM {actions} WHERE aid = :aid", array(':aid' => $aid))->fetchObject();
}

Yeah. Could this just be an oversight that actions are not currently being worked on to become configurables? Is there some reason for them not to be ones?

BTW two relevant issues for actions: #1788104: Convert actions to plugin sub-system and #1846172: Replace the actions API neither of which have been progressing lately. :/

Updated issue summary.

I've added both those issues to the summary

A set of issues hangs on list controllers and forms
primary #1855402: Add generic weighting (tabledrag) support for config entities (DraggableListController) - holds configurables with weight
#1872870: Implement a RoleListController and RoleFormController
#1788542: Use EntityFormController and EntityListController for image styles
#1809376: Use EntityListController for image styles
#1891690: Use EntityListController for vocabularies

#1882552: Deprecate menu_list_system_menus() and menu_ui_get_menus()
#1882218: Remove static menu link creation for menus in menu_enable() and elsewhere

#1978112: Convert taxonomy admin path to follow other core entity patterns

Updated issue summary.

Removing myself from the author field so I can unfollow. --xjm

Action has an issue and is already in the list, added reference to related rdf mapping issue

Add date formats

#2042807: Convert search plugins to use a ConfigEntity and a PluginBag and #1778410: Throw exception when RDF namespaces collide are the only remaining issues, demoting this meta.

Fix url

Let's close this because only 1 left #1751274: Do not query user_roles directly
