Consolidate most repository types into a repo module.

Having them contained in the individual endpoint groups conveyed an unintended sense that their intended scope was _only_ that endpoint group. It also made most repo-related import paths _quite_ long. This splits up the repos as follows:

* "General applicability" repos - those that are only loosely connected to a single task, and are likely to be shared between tasks - go in crate::repo.

* Specialized repos - those tightly connected to a specific task - go in the module for that task, under crate::PATH::repo.

In both cases, each repo goes in its own submodule, to make it easier to use the module name as a namespace.

Which category a repo goes in is a judgment call. `crate::channel::repo::broadcast` (formerly `channel::repo::messages`) is used outside of `crate::channel`, for example, but its main purpose is to support channel message broadcasts. It could arguably live under `crate::event::repo::channel`, but the resulting namespace is less legible to me.
