Hi,

Update to take account of MPLS-RT reviews.

Many thanks to them for their input.

> Abstract:
>    The MPLS Generic Associated Channel (G-ACh) is a generalization of
>    the applicability of the Pseudowire (PW) Associated Channel Header
>    (ACH).  RFC 5586 defines the concept of TLV constructs that can be
>    carried in messages on the G-ACh by placing them in the ACH between
>    the fixed header fields and the G-ACh message.  These TLVs are called
>    ACH TLVs
> 
>    No Associated Channel Type yet defined uses an ACH TLV.  Furthermore,
>    it is believed that handling TLVs in hardware introduces significant
>    problems to the fast-path, and since G-ACh messages are intended to
>    be processed substantially in hardware, the use of TLVs in
>    undesirable.
> 
>    This document updates RFC 5586 by retiring ACH TLVs and removing the
>    associated registry.
