This version leverages a flexible, cleaner key-value strategy
reducing the need to design entire new headers for every feature
addition, change, etc.
* A friendly declaration for the module authors, with minimal
requirements to fill in, and explicit labels of what the fields are.
* Repetition of keys, removing references to (and the requirement to
build) a clist, hlist and hfnlist and caplist and whatever the future
holds.
* Safe deterministic loading and unloading. Keys are evaluated in
order, errors can be recognized, and unloading occurs in reverse
order.
ircd: Refactor internal half of modules.c, with some V3 additions.
Provides better delegation for versions, a cleaner stack with better
error handling, and some functionality deduping. V1 and V2 handlers
are still somewhat unaltered, just factored in.
There's no reason to really have these in the main ircd anymore, static
modules are dead and aren't coming back.
To ensure people don't do something hopelessly retarded, this is a core
module.
MAPI V1 is still supported for legacy modules, but it is highly
recommended to update to MAPI V2. It includes support for capability
tables, module descriptions, and implicit versions.
