PROTON-844: police handle-max in proton-j
* when receiving an attach with a handle > handle-max, the connection
should be closed
* when attempting to allocate a new local handle when handle-max are
already in-use should throw an Exception
* the default of 1024 handle-max is quite small when proton-c appears to
default to 4294967295 - increase it more modestly to 65536
Closes #16

> proton-j: ArrayIndexOutOfBounds exception if remote peer sends a handle >1024
> -----------------------------------------------------------------------------
>
> Key: PROTON-844
> URL: https://issues.apache.org/jira/browse/PROTON-844
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: 0.9
> Reporter: Dominic Evans
>
> If a remote peer attempts to attach with a handle >1024, its advertised
> handle-max, a proton-j service will hit an ArrayIndexOutOfBoundsException in
> the call to getLinkFromRemoteHandle
> Similarly, if a proton-j client attempts to allocate a local handle when all
> 1024 are used up, it chooses UnsignedInteger.MAX_VALUE rather than throwing
> an Exception locally.
