1ea70a302b ignore protocol minor version 0 
The change from 0 -> 1 included incompatible changes
to CMD_BEACON and several others.

Ignore any UDP messages (beacon or search),
and disconnect any TCP peers, with version==0.

0084b6e60a de-virt Transport::getRevision() 
Makes clear that this is/was only for TCP,
and eliminate redundant storage.  Also apply
locking to this storage.

Use header version directly in search handler.
Correct as only UDP search is actually used atm.

on auth timeout.  Make sure it isn't success.

fa484a883a redo security (aka. access control) 
Break up monolithic SecurityPlugin API into three parts.

1. Authentication.
2. Authorization.
3. Access Control decision.  Left to ChannelProviders

d424202323 client: exception propagation from callbacks 
Swallowing exceptions here hides some of our errors.
Particularly unrecoverable introspectionRegistry misses.
Instead, propagate up to Thread and close connection.

fe5780521b Context::getSecurityPlugins() no return of non-const ref. 
Return of map as non-const ref. allows callers to modify.

da85d39c0c codec: const-ify socket 
Avoid possible data race of changing _channel

Was just using this as a boolean flag for a method
which is already guarded in BlockingTCPTransportCodec::close()
from being called twice.
