REORG: include: split mini-clist into haproxy/list and list-t.h

Half of the users of this include only need the type definitions and
not the manipulation macros nor the inline functions. Moves the various
types into mini-clist-t.h makes the files cleaner. The other one had all
its includes grouped at the top. A few files continued to reference it
without using it and were cleaned.

In addition it was about time that we'd rename that file, it's not
"mini" anymore and contains a bit more than just circular lists.
