Remove IOCP socket engine

IOCP has been experimental since its introduction, and has not worked
correctly for some time. Since we have no windows developer, remove the
dead code.

Most of the advantages of IOCP are not used by an ircd process regardless:
we do not use threads for our client processing, and we add an extra copy
operation that eliminates any gain from OS-level buffer reuse.
