Alfred Perlstein 34b94e8b82 Accept filter maintainance
Update copyrights.

Introduce a new sysctl node:
  net.inet.accf

Although acceptfilters need refcounting to be properly (safely) unloaded
as a temporary hack allow them to be unloaded if the sysctl
net.inet.accf.unloadable is set, this is really for developers who want
to work on thier own filters.

A near complete re-write of the accf_http filter:
  1) Parse check if the request is HTTP/1.0 or HTTP/1.1 if not dump
     to the application.
     Because of the performance implications of this there is a sysctl
     'net.inet.accf.http.parsehttpversion' that when set to non-zero
     parses the HTTP version.
     The default is to parse the version.
  2) Check if a socket has filled and dump to the listener
  3) optimize the way that mbuf boundries are handled using some voodoo
  4) even though you'd expect accept filters to only be used on TCP
     connections that don't use m_nextpkt I've fixed the accept filter
     for socket connections that use this.

This rewrite of accf_http should allow someone to use them and maintain
full HTTP compliance as long as net.inet.accf.http.parsehttpversion is
set.
