Support for pluggable resolvers

---

A resolver maps several kinds of names to addresses, or vice versa. Currently, only DNS host lookups are supported (but this can be extended if needed).

The plugin mechanism allows one to change the name resovler Ocamlnet uses. Resolvers can be both synchronous or asynchronous. Note however, that the default resolver is synchronous and simply bases on Unix.gethostbyname.

Asynchronous Interface

The following types are the same as in Uq_engines, here only redefined for systematic reasons

type 'a engine_state = [ `Aborted | `Done of 'a | `Error of exn | `Working of int ] 

class type ['a] engine = object .. end

Exceptions

exception Host_not_found of string

The type of resolvers:

class type resolver = object .. end

Synchronous Interface

val get_host_by_name : ?resolver:resolver -> string -> Unix.host_entry

Plugins

val current_resolver : unit -> resolver

val set_current_resolver : resolver -> unit
